Fitting Mk7 Front/Rear Alloy hubs to Mk5 TDi

[Stupots]

Hi All, I am looking to replace the bearings on all 4 corners on my TDI 4Motion (It's on 192K), and was wondering if anyone knows if the Mk7 (A3 S3 RS3 8V Quattro) hubs+carriers fit the Mk5? Has anyone done this? A search didn't turn up anything apart from Mk5/Mk6/Passat alloy hubs.

I'm looking at something like this (rear) https://www.ebay.co.uk/itm/143303555855
and this (Front) https://www.ebay.co.uk/itm/143290821617

Maybe @Pudding @Christiank or someone else has an idea?

Cheers

I wouldn't use them personally.  The rears look completely different to a MK5, and the fronts although very similar looking, have a different geometry.  The tie rod arm is considerably shorter than a MK5's, so your steering will be crazy responsive.  Too responsive!  You will find the steering will be very twitchy on anything other than a snooker table smooth road.

Personally I would go with Passat alloy fronts and Scirocco alloy rears, but bear in mind the Scirocco hubs will push the wheels 10mm outboard.  I think Passat rear hubs push the wheels out even further than that!

The Passat front hubs do also improve steering responsiveness, but not excessively.  Quite a good little upgrade.

Mk7 hubs are based from a completely different platform with is the MQB where the Mk5, Mk6, Rocco, jetta, passat etc etc is based on the PQ.

I've personally drive with Passat B6 front hubs, with Passat B6 wishbones and then also Passat B6 rear hubs.

When you look in ETKA same partnumbers is showing for the alloy parts from Cupra, Passat, S3  - the TT is different, can work but then you also would need track rods from TT. which is more work and not much gain.

Passat setup front widens about 6mm each front wheel
Passat setup rear widens about 12mm each rear wheel - I drive 18'' 225/40 on ET48 and rear tyres stick a few mm out from rear wheel fender.


With all that said…..  I've got no clue if the MK7 front or rear hubs will fit the your mk5. Rear calipers are different, but front calipers can be swapped as you like. I've personally drive with 4pot Audi TTS front on 340mm disc with mk6 R 310mm rear.

How rude; I never did reply to this... but thanks both for your input, it did directly affect my buying choices. 

I now have new genuine Passat B6 front hubs and 2nd hand wishbones and, as I have a TDI 4motion, some 2nd hand Mk5 R32 alloy rear hubs... all in my shed waiting to go on. I'm doing all related bushed and top mounts at the same time as well as new FAG bearings all round. I'll also get my H&R ARBs on at the same time... should improve the handling somewhat.

I'll post a few pics when I get around to actually doing the job.

If you really want to go all the way, find a 2005-6 passat AWD rear subframe in Aluminium ;)

[Stupots]

@Tharkhold Weirdly enough, the Mk5 Golf TDI 4Motion has an aluminium rear subframe already, but with steel hub carriers... not sure why the Mk5 R32 is the other way around with steel subframe and alloy hub carriers. I've still not got the front done yet as I want to put 345mm splash shields on when I do it (not important as the standard ones don't interfere with the larger discs, but I may as well while I'm at it) so need to order them first.

[pudding]

Interesting!  In theory the R32 should have the same rear track as the FWD MK5. Could be a better option than the Passat and Scirocco rear alloy hubs as they add too much track width.

[Stupots]

Bits are coming together. Still waiting on 345mm splash shields so I only have to do the job once :)



Both hub carriers are genuine VW AG, one has a FAG bearing (with VW logo) and one has NSK bearing (with VW logo). I kind of got the impression FAG is hard to beat for bearing quality. The top mounts are TTRS OEM and the top mount bearings are FAG. Wishbone/Control arms are cleaned up 2nd hand Passat items.

If you can, think about getting some Superpro adjustable balljoints on at the same time for a bit more camber!

[Stupots]

I think adjustable ball joints would be overkill for my 170bhp Diesel.

I'm mainly doing this to get unsprung weight back to what it was (following the addition of the Mk7 R Brakes) and my steel hub carriers are flakey and rusty. Trying to keep it a little bit VW OEM, but adjustable ball joints would definitely be a good option if I was going to track it. I'm planning on going 220BHP, but I only drive fast in a straight line (Dual Carriageways and Motorways).
