R32 Gtr, Gearbox Vibration And Rear Clunking

[gtovr4]

Hi Everyone,

I have 2 problems with my R32 GTR, nothing major but any advice as to what the problem is would be appreciated.

Gearbox Vibration: The gearbox seems to be vibrating when under stress (very high revs), I can feel it if I hold the gearknob, it isn't too bad, but vibrates none the less when put through the revs. Any ideas?

Rear clunking: A loud CLUNK CLUNK CLUNK sound coming from the rear, when I make very sharp right turns (usually in full lock.) A friend of mine was driving behind me and he says it appears that the back right tyre is bouncing off the road surface. What could that be?

Thank you.

Does your gearbox vibrate under stress or just high revs? When you go up a big hill without reving it up but put it under load does it do it then?

If your GTR is built up or the clutch is getting old you could be feeling the clutch slip under full power conditions. Remember that your car makes peak power at high revs so could be that your clutch is on the way out. It could also be that you are getting something in the drivetrain or motor transferring through the transmission. If it is a really bad vibration, I'd take it into a good shop or find someone on the boards here that can advise you. You'd hate to have something let go at those high revs.

Not too sure about the clunk sound. Before I changed the suspension on my 33 GTR it would lift a tyre on a violent hard turn - but that isn't bouncing. Could be a combination of worn pinapples, on power and hard turn - the rear diff cradle would bounce due to the pinapples and doing this while on power and hard turning would cause it to bounce as the power / traction works. Again, if you plan to do any performance driving with the car, I'd have a shop look at it.

Hey mate,

It is under high revs only, if I go up a hill, it is fine ??

The vibration isn't very bad, just noticeable if you hold the gear knob.

The clunking is something to do with my suspension, I think you're right.

Will get it sussed out when im getting my tune/service done.

Thanks.

the second ones sounds like a mechanical diff. does it do it most in tight corners (steering wheel on full lock)? left as well as right?

for most mechanical diffs it only clunks when you put the power on, so start rolling then turn to full lock see if it happens. if not it is probably just a tight diff and perfectly normal
