Audi S2 91 coupe quattro 3B
Hi, just got stuck 200 metres from my front door, on inspection of front wheels grease splatter iside rim with torn cv boot. when putting the car in gear and releasing clutch, whirrring sound coming from the front.
if the cv joint is knackered will the car be able to move if put in gear or is my clutch gone.

Thanks....

I guess it could be the cv or the clutch, the cv clearly needs attention, I would attend to that then see if you still have a problem?

I have not seen a CV joint fail to the point of spinning but not allowing a wheel to turn. Normally they make a cracking knuckle sound when the balls and retainer begin to wear out, usually due to the loss of grease over time due to a cracked boot. The whirring sound could very well be your clutch plate not grabbing due excessive wear. If you have no power to the wheels I would suspect the cluch, but also repair the boot.

If a CV joint is worn the car should still move when the clutch is released. Remember, having quattro you have power available to all wheels thru your transmission/differential via 3 output shafts, not just one.

If the car is not moving when in gear then you have a clutch issue (or worse!).

Thanks for the replies, took off the wheel this afternoon to get a better look,
i put the car in gear, and the front hub does not lock, knuckle sound definitely coming from the CV. from your replies above, I can engage gears easily, without any forcing or grinding, can that still be a clutch issue?

Kind Regards

If one of your cv joints isn't working / has collapsed the car will not move

Agreed, I once had an 80 16v which lost all drive in the middle of the town centre. When I got her towed home I put it up on the ramps to find all the bolts on the inner CV had come undone. I only had the car a few weeks so can only assume some muppet hadn't done them up right.

With the outer joint being a spline fit it's unlikely ifs busted. From memory the fronts aren't held on with a circlip so could have pulled out.

With this being quattro It would also be worth checking the prop at the back of the gearbox.

Actually, I've never know a clutch that wasn't already slipping to suddenly lose all drive. It's usually the opposite and you cant get them into gear. I suppose the centre of the clutch plate could detatch from the friction pads if it had been given some abuse????

But then it would whirr in nuetral as well as in gear. If it's only when in gear it suggests that the clutch is working and engaging drive to the gearbox.

Just read that bit, if the other wheel is still on the ground it won't lock as the diff will allow the wheel off the ground to turn.

Hi guys, took the car to a Mach for a diagnosis and repair of the Cv. Yes, Cv boot is torn but the Cv is still intact and doesn't show any sign of being broken, thus turnimg the the front hub, still slips, and also that slipping grinding sound taking place from the back diff or prop, cant make heads or tales from this.....

Thanks..

Sorry to say, it sounds like a rebuild or replacement rear diff is needed? Try draining the rear diff oil, see if any lumps of metal fall out?

hi, just a update, had car towed again, to a reputable repair centre, guy insist it's the gearbox, even got a second opinion confirming it's the gearbox, not so sure anymore, can a gearbox die silently without any warning and noise....?

thanks...

I was driving my works 61 plate Renault traffic sport van a little while
Back that only had 31000 on it, I pulled away from traffic lights and it jumped
Out of 2nd gear about 3 hrs later the gearbox went!!! Lucky it was under
Warranty!!! Renault fixed it got it back I took it to the bull ring in Birmingham
And reversed it into a post!!! Opps! !! Boss wasn't too pleased.

His location is South Africa which could be a clue.

I'd remove the inner cv joints and check the splines on the driveshafts for wear
