Loose inner CV's and steering wheel wobble

[Neil VR6 0]

Went out yesterday in the Rado and there was a weird vibration coming thorugh the steering wheel when you accelerate hard in 3rd and 4th. (New inner CV joint worked loose the other day and required a tow from the AA) I slowed down the pace a little and pulled into a nearbye garden centre. I had a look at the CV joint on the gearbox side (the only one you can see from the engine bay) and one of the feckin' bolts had worked it's way loose. When we got back from shopping, I went round to M&D's house and jacked it up and every single bolt which holds on the CV joints, both sides, we either loose or not done up very tightly at all. I don’t know if this would have caused the wobbling though? I reckon not. I also went to Kwik Fit (the only place open on a Sunday) to see if they could tighten up the bolts but they're not allowed to touch anything that isn't tyres and brakes. However, the unexpectedly helpful bloke there said that he doubts if its wheel balancing. Needless to say that in the difficult conditions of working under a car in cramped conditions I have rounded off about 4 bolts whilst tightening them up. Any ideas on the source of this wobble and why my CV joint insist on working loose? :( Corrado patience is wearing very thin at the moment :(

im sure the inner cv bolts are stretch bolts and would need changing

[Neil VR6 0]

Mmm, that would make sense if they were. I'll have to get back onto the garage that apparently "fixed" it.

You've not had a clutch change by Mr Clutch have you?

[Neil VR6 0]

Nope, clutch is old though. Don't know when it was last replaced? Could that be the problem?

[Supercharged 2]

Nah, it won't be the problem...

Neal - give your very helpful, more than accomodating specialist John Mitchell a call and he'll put your mind at ease. If anyone will know.......

 

Was the garage that did the CV work non VW and just around the corner - i've been there to.

Yeah, it's just such a way to go for what should be something very simple and easy.

 

"Was the garage that did the CV work non VW and just around the corner - i've been there to." ?? The garage that put the CV's on was a local to where I work place. (That I will never go to again)

I've still got this problem and it's now worse than ever. It's now present from about 30mph and seems to be road speed related rather than engine speed related.

 

What is there in the gearbox that tuns at "road speed" that could be out of balance? I'm at a real loss here.

 

The car's in a local garage and so far they've drawn a blank; although they haven't taken anything apart yet.

output shaft ...?

[Neil VR6 0]

I assume that's the bit that the CV's locate into in the gearbox? How would this become "unbalanced"?

Neil, I know you said its in another garage now but before you start worrying about gearbox internals I'd check the basic mechanicals are ok ie wheel bolts (especially if garage left your cv bolts loose!), engine mounts, all suspension related bolts. Might also be the balance weight on one drive shaft has come loose.

Keep us posted on findings

[Neil VR6 0]

Well I had it down at G Werks and they tightened up everything you said. Might try the balance weight thing though. cheers

Have you recently fitted aftermarket alloys to the car?

 

If so be wary as some require spacers, if you do not fit the spacers, the front steering can go bonkers as if the CV joint has packed up.

 

I have two sets of rims that I run mine on TSW Stealth's and BBS RM splits, the Stealths require spacers and the BBS RM's don't.

How's the diagnosis Neil, you getting anywhere?

[Neil VR6 0]

It's a nightmare. The car has been trailered back to the place where I originally had the CV's fitted. My local place said I should really take it back to them which is fair enough.

 

My local garage (Joe's- a VW specialist) said that there's usually a small amount of "play" in the driveshafts and there isn't it mine. The garage it's been trailered to (PTA) are talking about machining a small amount of the CV off to afford this play. But it was fine with the old CV joint, granted they were worn and clunking, but they didn't need to be machined. To me, this isn't the answer and something is wrong. Also the vibration coming through the steering suggestst to me that something is majorly out of balance.

 

This is one of those very boring and unglamarous threads! My Corrado patience is wearing very thin as the car's been off the road for weeks now. :(

 

I tried calling John (16VG60) but he's really busy at the moment so I'm a little short on expert advice.

 

Garry: Wheels are std 15 inch BBS G60 wheels, recently balanced too.

[Supercharged 2]

Sounds like they've fitted either faulty CV joints or the wrong ones completly!

[Neil VR6 0]

They've double checked this with EuroCarParts and apparently there's only one inner CV for all Corrados. It's also common to some Mk3 Golfs and also Ford Granada's he said.

[Neil VR6 0]

The cars still in the garage now and they're trying some H&R camber bolts I bought but never got round to fitting. They reckon that the driveshaft is in compression owing to the car being lowered and (according to them) running too much negative camber. Why this would manifest itself to this extent only when some new inner CV joints are fitted I don't know. I haven't driven the C for about a month now. :(

[2cc 0]

Bummer mate, but I agree with supercharged thinking they're the wrong parts. You don't have to disturb the hub position to change the inner CVs so if the new ones are now 'tight' then I'd deffo suspect them.

I'm surprised if ALL Cs have the same inner CV as I thought there was a difference in drive shaft diameters - but I don't really know. Can someone with ETKA confirm part numbers? Might throw something up. Sorry, doesn't help at all.

[W3RKD 0]

All corrado's do run the same inner cv's along with alot of other vag models.

I'm now having it trailered down to John's so he can fix it properly. They wanted to machine down the CV joints. It was at this point that I said I'd just take it away! Hopefully this will mark the beginning of the end of the saga!

It's a diff support bearing. I need a new or reconditioned or rebuilt gearbox. :(

i would recomend that you have your own box rebuilt then you know exactly what you are getting pm me if you want details of very good gearbox builder
