Hi Guys:dance:

 

My 91 auto TT is driving absolutely perfectly except........

 

at speeds of over 65mph when the revs are at 2500rpm there is a rumble from what sounds like the rear of the car. If I raise the revs to 3000rpm it disappears, as it does when you drop to 2000rpm.

 

Around town and at low speeds it is perfect but if I stay at 70mph, either manually or in cruise control the car drives at 2500rpm hence the problem.

 

It is quite a worrying noise and will stay there continuously until the revs move 500rpm in either direction.

 

I hope someone can shed some light on this one:)

what happens if you have it in nutral or with clutch in at that speed does the noise go away or stay? if it stays then possibly a prop shaft noise or diff noise (usually prop centre bearing) could also be the gearbox mount sagging.

Its an auto buddy

ok well cancel the bit about the clutch, but have it in nutral?

It could be the propshaft bearing, same thing happened on my NA Auto it's on acceleration it would give a low thrum around 2500rpm

Thanks for the response guys. I will slip it into neutral next time I am out in it. If it is the propshaft bearing is it a big job?? How urgent would it be to do(i.e. is it dangerous)I will let a garage do it but just wondered what to expect.

Thanks again.

I ran mine for a good 6 months before i replaced it and it was fine so no serious rush
