So is it only in 6th between 75/85? I had similar and it was my gearbox giving up. That was in 1-4th though and 5th and 6th were fine.

If its a quattro its your rear prop bush happened to me changed that now perfect

I had a similar problem, replaced my rear prop bush but still have the same noise, been told to check my wheel bearings next.

no its just more noticeable at them speeds. hard acceleration will do it aswell

hi yes been thinking it was the rear damper myself aswel as the front coupler don't get much luck with this car

 

[bigal23]

Its its between them speeds its 100% I put life on it that its the rubber doughnut at the rear

was also told to have rear wheels balanced for the vibration

 

[bigal23]

Highly doubt its the wheels causing vibration like that. I tested mine before buying a new doughnut by lubing the old one up loads and working it back and forth with a screwdriver then going for a drive stopped the vibrations for a while but came back just as bad so changed it and been sorted ever since but there not cheap

 

[jessie123]

Hi thanks bigal23
How much is the doughnut or damper as some people call them
Ps thanks for the replies butt

 

[bigal23]

Around 180 for rear 60 for front but doubt you would need a front one. I got mine off a guy on here who had a spare new one for 80 well it was a pair front and rear but only fitted the front.

 

[jessie123]

thanks I was quoted £264 by tps start to look around I think

My friend has a new one which he never fitted. I'll check if he still has it and post back here.
