Title: Wheel hop crazy - front left
Post by: SteveS on October 25, 2010, 06:33:38 pm
Ok, so as the title... I get crazy amounts of wheel hop from the front left wheel.
Now, i do not believe there is any upgrades on this car in relation to engine mounts so im going to sort out a VWR lower one. Other two maybe in future..

Just wondered if anyone had any ideas really... I have the VWR LSD which i would have thought would be helping this issue but seems not to be.

when was the diff fitted ? i would go round and check bolts , vwr left my shocks loose and denyed all knowedge

Christ, that doesn't sound good.
I believe Paulk had it fitted around march.
Wouldnt know what bolts to check?

i have just checked and it looks like i have the vwr lower mount fitted already!

lol, If i knew where to start. i had a look today and saw nothing but i dont really know what to look for..

only thing i noticed today when i looked today was the tire pressure was 2.6 on FL, other 3 were like 2.4.
Title: Re: Wheel hop crazy - front left
Post by: rich83 on October 30, 2010, 05:10:18 pm
Tyres should be 2.6 all round according to the handbook!

I changed the side mounts yesterday, and the gearbox side mount was very sloppy, I wonder if this would cause your condition????

Post by: Saint Steve on October 30, 2010, 05:45:17 pm
Put the car back to stock steve, see if it still bounces. At least that will tell you if its too much power or a mechanical /suspention etc/ issue with your car.

no not at all, didn't have an issue, but I wondered if the amount of play in the gearbox mount could cause something like this????

I would suspect the console bushes if they are still the original.
Title: Re: Wheel hop crazy - front left
Post by: john_o on October 30, 2010, 08:55:59 pm
usually a good sign somethings loose. either bushings or fixings

can you move engine by hand back and forth?
subframebolts could be loose
balljoints etc
how much does the engine move when taking up drive against the handbrake ? (try it with bonnet up)

if you can prove nothings loose , and its the side mounts then get them changed. even going to OE would help , but id advice going to THS or even to VWR as a better long term option

Im assuming the shocks arent past their best (ie no oil?)

Title: Re: Wheel hop crazy - front left
Post by: SteveS on October 30, 2010, 09:13:40 pm
if i knew where the subframe and balljoints were i would look :p
how do i check suspension oil??

i have tried contacting matt at VWR but he never replys to the emails i have sent, during the week its very difficult to get time to call. rather annoying.
Title: Re: Wheel hop crazy - front left
Post by: john_o on October 30, 2010, 10:12:53 pm
you dont check shock absorber oil per se, more look for leaks and confirm it rebounds correctly on that side. (push on strut tower on that side , it should be firm)
shocks (as well as mounts/tyres etc) are all interlinked in terms of getting wheel hop dynamics.

the other thing to look for are 'shiney seating areas' where theres a loose bolt and the item moves around.

i all honesty, youre stuck getting VWR or another competent garage to look at it  :happy2:

Post by: Teutonic_Tamer on October 31, 2010, 10:52:41 pm
If the wheel hop is only on the left side - then this strongly points to suspension issues.  Worn mounts will affect both sides nigh-on equally (even if say just the gearbox mount is fooked).

Steve, do you hear any cluncking or knocking?  Does a front seat passenger feel any banging through the carpet/floor?  Are you able to jack up the car and remove the front left wheel?  If you can, look at the suspension strut - the central tube between the coils of the spring - check the outer 'paint' of this tube - it should be dry and completely oil free.  If there is any evidence of oil weepage - then your shock absorber is knackered, and this will be your cause.  (If the shock is toast, you must replace both front shocks as a pair).
Title: Re: Wheel hop crazy - front left
Post by: john_o on November 01, 2010, 08:13:47 am
would slightly disagree there TT. Mine always used to hop with a 90/10 preference to one wheel
unequal driveshafts, tyre pressures , camber of road (nearside cambers to gutter) etc all bias.
But yes SteveS issus sounds like somethings loose  :happy2:
Title: Re: Wheel hop crazy - front left
Post by: SteveS on November 01, 2010, 09:17:22 am
i do hear a knocking "though the floor" when turning (tightish) i.e. into drive, round small roundabouts...  :scared:

Post by: tmagnet on November 28, 2010, 08:20:42 pm
I've started to get a bit of wheel hop on the NSF- hoping it's due to the worn out gearbox/engine mount. May be worth checking yours
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 23, 2010, 04:07:25 pm
OK, so i got these engine mounts fitted, hefty price tag of £540? or just under... and the wheel hop is just the same, i got to test it on the day but i confirmed it was gone! why... because somehow my REVO got reset to 000!!!!! no wonder it was fine!!!! shear lack of power!

So now i have put the settings to REVO stock not even proper settings the hop and banging is back... the banging isn't AS bad, maybe because the exhaust isn't banging around underneath, but wheel hop still present...

im extremely disappointed after being recommended to fit these to resolve it... i have emailed Matt @ VWR so waiting reply.

any other ideas welcome...
Title: Re: Wheel hop crazy - front left
Post by: john_o on December 23, 2010, 05:22:47 pm
Steve, why have the mounts fitted when it wasnt even confirmed that they were the problem?

Sounds like the same thing that was a problem before still is...
worn joints/bushes/suspension components/top mounts to name but a few.

on the plus side its a good mod anyway  :signLOL:
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 23, 2010, 06:17:12 pm
I went to VWR for them to check it out, Simon said engine mounts would solve it... so i had them done... they said everything else was fine
Title: Re: Wheel hop crazy - front left
Post by: RedRobin on December 23, 2010, 06:22:32 pm
.
On the face of it, engine mounts and especially the lower mount, would solve wheel hop or at the very least dramatically reduce it. So I think that Simon is right to think that it would.

I'm confident that VWR will sort it for you and expect that there's another factor in the equation such as john_o suggests.

Am I right in thinking that immediately after you drove out of VWR's workshop with the mounts installed, you didn't have the problem?

If you did have the problem why didn't you return to them immediately?

If you didn't have the problem how much later did it start happening?
Title: Re: Wheel hop crazy - front left
Post by: Janner_Sy on December 23, 2010, 07:18:42 pm
it wasnt as pronounced as before RR as for some reason his REVO had reverted to stock output. 
Title: Re: Wheel hop crazy - front left
Post by: MAT ED30 on December 23, 2010, 07:20:58 pm
bloody miles away  :sad1: is it defo wheel hop or is the noise coming from your dm flywheel ? ie what clutch is in your car as its got a diff as my clutch started to bang once i had the diff done as the car suddenly had all this grip it never had before as it would just spin the wheels before the diff was done  :driver: oh and the battery has to be taken out to do the mounts hence y revo was at 0000
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 23, 2010, 07:21:15 pm
exactly, i checked the revo when i got home on the laptop and it was 000
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 23, 2010, 07:24:25 pm
im pretty sure its hop, can feel the car bouncing around.. but then i dont know what the flywheel would sound/feel like to compare.

They knew it has REVO map and if they took the battery out they know/or should have known it would reset and so they should have put it back, so that in itself upsets me, say i didnt have a select switch, i may NEVER have known and thought the car had other issues... not acceptable really

....VWR aren't a Revo dealer AFAIK and the reset back to your Revo map would have been your, not their, responsibility to do with your Select switch. I would have expected them to at least ask you about resetting the Revo but that assumes they know about what disconnecting the battery does on Revo, which I'm pretty sure they do know.

But either way, something is clearly wrong with your particular car. I'm on Revo2 with VWR's 'Fast Road' mounts and Quaife diff and I can't induce wheel hop!

Could it be a suspension component failure? Broken bush? < I've now just read other folks suggesting suspension too. I have KW-V3.
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 23, 2010, 07:44:33 pm
I have to say i dont totally agree with you.
They do suppy REVO now, they put it on in the first place!!.. and even if they didnt, it should have at least been mentioned if they were unsure.

They said they checked these things out, i took the car there to be investigated for such issues and told there were none! so if there is an issue with one of these obvious parts i wont be a happy bunny..

Just curious but does it occur when you have the traction control turned off ?
Title: Re: Wheel hop crazy - front left
Post by: SteveP on December 23, 2010, 10:09:23 pm
The battery would have been removed to fit one of the mounts, so the Revo code would have defaulted back to stock mode.

Post by: rich83 on December 23, 2010, 10:13:03 pm
Come on guys... you shouldnt need to spooge 1200quid on KW-V3 to stop wheel hop! There must be something not right with one of the front end components!

sorry to hear you have problems steve....Vw racing fitted all the mods on the car , diff miltek REVO etc ....I never had any banging knocking from any thing , the suspension felt tight no oil spills etc. I always had the car checked and can say nothing was loose...Id take it to another tuner for some else to look it over before you spend any more money.

I will say the diff did kinda skip when it was workin hard tryin to get grip, the rs does the same....

....Installing the two front engine mounts WILL most definitely transfer more sounds from the engine bay to the cabin - I can't believe Simon @ VWR said otherwise.

I guess that weather conditions stopped you from doing a proper test drive by hammering it through a few of those Milton Keynes roundabouts.

I would go back to VWR before approaching any other tuner - VWR will be very keen to make sure your car is as it should be and will in my long experience of them always do all they can to help. Mixing it up with third parties at this stage helps no-one.

VWR open again on January 4th.

Post by: SteveS on December 24, 2010, 10:46:42 am
Yes, the engine sound has transferred, i quite like it, but still... issue not fixed by installing the mounts.

I will go back to vwr, i don't trust any other tuners anyway.

Post by: tony_danza on December 24, 2010, 10:54:53 am
Why are you trying to cure wheel hop with engine mounts?

Wheel hop is the car's wheel being pulled forward under hard accelleration into the wheelwell, it going from toe-in to toe-out, losing traction and snapping back. You replace the lower mount to stop the engine from rocking when this snap occurs, making it feel worse.

Mounts don't cure it. A diff won't cure it. KW Vinfiniti won't cure it - all they do is alter the threshold at which the wheel hop occurs. Short of running solid mounts on the wishbones (rosejointed) you'll never completely eliminate it, but you'll make it a hell of a lot better with poly.

If nothing is worn or loose, shocks/topmounts etc, then first port of call is to poly the wishbones if they aren't already done.

As a slight aside, you have a diff - are both wheel spinning, or just the nearside?? It could be shagged and that could be your problem, it isn't torque biasing??
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 24, 2010, 11:06:20 am
Hmm, im not sure if the wishbones were changed to S3 ones? ill have to find out.
When i was at VWR i did say do we need to change any of these, they said nah, no need...

The hop is coming from the passenger/nearside.

Now you mention it,  i think it was pulling to the left, but then i know they are meant to, Ill check on torque steer tonight and how much it pulls.
Title: Re: Wheel hop crazy - front left
Post by: tony_danza on December 24, 2010, 11:11:29 am
You've got a WALK??

If not, get the Superpro version (much cheaper and arguably better). The front wishbone mount isn't as essential, but it'd be daft not to do it too.

A full set of mounts is overkill, I can't help but feel you've been led down the garden path there if you were sold them on the basis of them being a wheel hop cure. I'd class them as a 'nice to have' and not a 'need'. I certainly never felt the need to have them on mine, and that got some serious abuse on track.

To check the diff, axle stand the car and put it in a forward gear on tickover. Both wheels will rotate in the same direction if it is working ok. For the second part, it being faulty under load, you'd maybe need to seek some expert advice there, but it'd been a really really slim chance of it being the cause, so don't focus on that too much.

Oh, and mine never pulled to the left.  :confused: You've had the rear geo checked, right?? They're way out from the factory, straighten it up and it'll track true.

As a slight aside, you have a diff - are both wheel spinning, or just the nearside?? It could be shagged and that could be your problem, it isn't torque biasing??

....IIRC, in my case I found that the coilover suspension with WALK and new wishbone bushes setup (all installed in one session) reduced wheel hop. Later on I found that when I only installed the lower engine mount it further helped transfer power to the road smoothly. Surely there is also the factor of driving-style - I have trained my right foot to move progressively and not stamp on the throttle - I don't like wheelspin and feel I'm not driving properly if I induce it.

I'm thinking it can be a combination of components which help reduce wheel hop. There's no doubt that even only fitting a poly torque arm insert reduces the hop, so logically at least, a stiffer lower engine mount will help a lot.
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 24, 2010, 11:17:57 am
I asked about WALK and they said don't bother as you have the S3 version fitted

The mounts came with a hefty price, so quite disappointed, still they do make me feel more "connected", but that i could have lived without, the hop i cant, needs to go!

I didn't ask to have the geo checked, they didn't suggest.. so i don't know the answer to that.

Where you from tony?

Title: Re: Wheel hop crazy - front left
Post by: tony_danza on December 24, 2010, 11:23:56 am
Robin, the WALK cured it. Trust me, I did mine in stages.

All the other mods purely serve to aid traction, so the threshold being moved gives the impression they've improved the problem. The lower mount reduces the movement of the lump, so it doesn't accentuate the hop with it adding it's own bang. 2 different issues there working together.

Steve, the S3 mount is still soft rubber and compliant, even if it isn't as bad as the voided GTI version. Your issue lies here. Poly them, get the car on a 4-wheel laser geo and have it set up properly. It'll be much, much better afterwards.

I'm in Cheshire BTW.

....I agree - Engine mounts are definitely great to have but not needed, but you could say that about most aftermarket modifications. In fact I had to ask VWR to fit them - They didn't hard sell them at all - In fact, VWR never hard sell anything in my experience. Likewise with the S3 wishbones: VWR can supply and fit them but advise me my car doesn't need them and we can do a simple wheel arch mod instead. Don't forget that although they are a business interested in profit they are heavily subsidised and workloaded by their racing activities and don't seem desperate for work.

Polyurethane bushes... http://www.powerflex.co.uk/products/Golf+Mk5+1K+inc.+GTI+%26+R32+%282004-%29-737/1.html

WALK... http://www.awesome-gti.co.uk/product.php?xProd=11788

The WALK comes with poly bushes as standard
Title: Re: Wheel hop crazy - front left

thanks!  :happy2:

So makes sense to buy the walk with the bushes then?
Title: Re: Wheel hop crazy - front left
Post by: tony_danza on December 24, 2010, 11:31:50 am
Sorry,

Poly is the material, WALK is a brand (Whiteline Anti-Lift Kit)

You want:

Superpro front arm control bush ref: SPF3346K
Superpro rear arm control bush with anti-lift ref: SPF3273K

Anti lift basically means an increase in static caster, which generates dynamic camber. It forces the inside wheel down to retain traction and cambers the outside to increase tyre footprint. In tandem with your diff and decent geo, it'll feel a million times better if you add these. I was one of the first to use the more expensive Whiteline version* years back and it's very impressive.

The only difference is Whiteline supply their own metal mount, you press the Superpro one into the OEM one instead.

....That's good to know about the WALK's  :happy2: I should read john_o's excellent review more carefully.

Yes, I'm a great believer in how different components can work together: 2 + 2 = 5  :grin:, or 2 + 2 = 3 if you have a problem. This is also why every single car is different to another.

Not necessary as tony_d pointed out earlier, but you may as well replace the poly bushes on the opposite end of the WALK's on the wishbones while there - It should theoretically better balance the bush stresses across the wishbone.

The walk really does increase traction by quite a margin... well worth it!

Robin.. i thought as a die hard modder you'd have the WALK kit on!  :wink:

This is how the Superpro one looks, see how it is offset to change the wishbone's angle?

I think your going about this all wrong, Your just adding loads of expensive part's trying to cure a fault. I personally would first off swap my front tyres for the back ones, just to see if this cures it. This will discount the tyres from being the problem. Then i would take it to a different reputable garage and get them to go over all your bolts and suspension connection's to see if something is a-miss. VWR are great but they quite often make mistakes.
Then if all check's out ok you need to start looking at wheel alignment and such like. There is obviously a fault  on something as you should not be getting excessive wheel hop, some perhaps occasionally but not all the time.
I am no mechanic, but it's common sense to trace and fix a fault before just buying bits hoping to cure it.  :santa:

Check. If all ok, do what you should have done first of all and do the bushes & geo.

Bad form on being relieved of a £monkey+ for something you didn't need.

Are you sure this problem is this VWR LSD u have installed Steve?? 1st thing I would question, especially as vwr and their spanners have anything to do with it.
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 27, 2010, 01:02:27 pm
I asked th to check it out when it went it. That was the point of my visit. Although don't know if they did. Just said it was all fine

I'd go independent for their advice personally, try a local performance car specialist to you mate and get a non biased opinion.

Post by: john_o on December 28, 2010, 07:50:14 pm
what are your front tyre make/pressures Steve?
maybe also worth having another forum member jump in the car to confirm its wheel hop.

with mounts fitted it should just spin freely without any greate 'hop'
would disagree with tony_d on the engine mounts, but he is the WALK/suspension expert  :happy2:

still think you have something loose/worn tbh
Title: Re: Wheel hop crazy - front left
Post by: SteveS on December 28, 2010, 07:57:23 pm
seems like two opinions here. some saying the mounts will fix and some saying they wont..

The hop is there and with REVO on is clear.

I have just met a guy who works in a tuning garage, power engineering in uxbridge. so ill try see if he can do me a "favour" and check it out.. hopefully he'll have an alignment machine too.

cant remember on presure, ill need to check them.

Tut tut shame on you steve the only thing vwr do is take the gearbox out and put it back In and that's it as it takes a machine shop / special fitting to put the diff In.

It appears JBS are doing an offer on the superpro products until 4th, so i may get the front and rear with anti-lift.
I guess anyone can fit, and then ill have to get aligned.

Found a company right next to my work who will fit and align for £140.
Ill get them to check the susp while there at it

OK, so an independent garage where i work did me a favor and took a look.
Its the exhaust... Miltec 3", where the cat is, its hitting down just behind where that bracked with those two red bits are. Can see the marks on the cat!!

I have contacted VWR, told them, im calling back next wednesday... and then booking it in... im guessing the shape of the bend isnt right...  :fighting:

Although thats the noise, why its moving around makes me think its down to hop, causing it to travel up and down...

....Ah yes! I know this problem (or similar). It's why Milltek included a free torque arm insert in their new systems. They have probably revised the fixings too. However, a lower engine mount should have helped but it may have been on the way out before installation.

It's not so much the exhaust itself but the jolting from the extra power it's being subjected to on a remapped car.

Post by: SteveS on January 13, 2011, 07:37:27 pm
Even worse! its a known issue and VWR still didnt even check it obviously.
Had a good look under it, why its designed so close to the left\bottom side wall is very odd. there is masses of space to the right and up!

Post by: Saint Steve on January 13, 2011, 07:53:13 pm
I'd ask the previous keeper of the vehicle where he got the exhaust from.Doubt it's the shape of the bend.

Was the exhaust a 2nd hander, supplied by vwr? Or do you have a receipt where it came from originally?

As far as im aware and Matt at VWR didnt argue, they supplied and fitted it. He seems silling to help which is great, as long as its efficient.

Has blueflame on my last, did love it, maybe alittle louder than i wanted and wasnt R32 style :)

To be fair with that much power and havin used standard engine mounts besides the lower one,something had to give. i had the same probelm on my car and the engine movement was excessive and caused exhaust knock.maybe it needs readjusting? replacing the engine mounts was a good shout first i think and it would have had to been done sooner or later.

....No links that I'm aware of. I've had detailed discussions with Milltek's boss man about it and also their factory manager. You might find something on Milltek's web site though.

Yes was helpful when we spoke, he wants me to see another garage closer as he thinks its the way its fitted and believes there is a joint which can be turned to situate it differently.
i looked and dont see this joint so im not too hopeful. im waiting for a reply, so we will see
