advice needed snapped bolt when doing wishbone

[viewsonic]

changed the front wishbones of my 2.0 tdi golf yesterday

first one easy 2nd one for some strange reason the bolt snapped first time it had been took of too

was moving the bolt back and forward and spraying wd40 on it and it snapped right at the head end aint a clue why it was so tight like

it one of the 3 long bolts which hold the main bush in

so just driving on 2 bolts till i get this fixed

only about 5 mm of the bolt showing and the bolts are around 3, somethink inchs long

what is the best way to go

i was thinking of drilling the bolt then put a slighter longest bolt through and the a washed a nut of other side of steel plate as there is room to do this

any advice would be great

Ive had quite a few snap before.  I drill them out and fit a timesert.  Then use a new bolt.  Its not fun drilling through 70mm of steel.

I buggered my drill bits with one disc retaining screw

dont suppose it will make any difference just putting a bolt through and bolting the other side as makes it hard anywise getting the right bolt etc


what drill bits do u use and what sort of time to drill it

Had one car snap three bolts.  Took around 3 hours extra to drill and timesert. Using cobalt drill bits that are around 100 quid a box.

I had one snap when changing console bushes, but thankfully it was one of the 2 smaller diameter bolts. The bolt on my car hadn't turned much before it galled, then with surprisingly little torque the head snapped off.

To get the bolt out on my car, I removed the longitudinal subframe part, turned the bolt back into the subframe (as if doing the bolt up) using a stud extractor, and then when sufficient bolt was showing through the subframe I welded a nut to the bolt. I then cut off the section of bolt I'd damaged with the stud extractor and used the newly welded nut to turn the bolt and extract it from the subframe.

Thankfully the bolt on my car had galled due to corrosion / dirt on the upper face of the subframe, so the thread damage was very very limited and probably only about 1/10th had visible marking. I ran a tap through to clean up the threads, then fitted the console bush with new bolts.

off to do it in 30 mins wish me luck just going to drill and bolt it

the 10.9 tensile bolt was too hard

so just drilled a hole next to it as was on the side where the 2 bolts go  and bolted it

job done

Were you using a wood drill bit?  A quality set of metal bits sail through.

na metal drill bits not a 100 quid set tho

you should be able to drill through a snapped bolt if you use plenty of cutting compound, small pilot drill then the final size just smaller than the bolt, center punch it first and then run a tap down to clear the threads that should work done it a few times myself
