I may of slightly exaggerated. I posted a few weeks ago about unwanted steering vibration at high speed. After lots more rigorous high speed testing 80-100+ (in germany/private runway/track/isle of man/moon). The problem seems to of got worse and seems to be linked to acceleration. At said speeds anything more than light acceleration in top seems to cause the steering to judder which then subsides on a constant throttle. It also seems to be coming from the engine/drivetrain rather than the wheels/suspension etc.

Any ideas? Or things i can do to try narrow down the problem?

Any help is much appreciated. Thanks in advance for your help.

I would suggest to check the balancing on the wheels, maybe a wheel weight has fallen off. I had a similar sensation once, only getting a vibration under hard acceleration. Turned out a wheel weight had gone. HTH

yeah i agree, have the wheel alignment checked and adjusted in necessary. may only be out by a mm or so but could be enough at those high speeds

imminent dmf failure......

Hmm i had the wheels balanced and the tracking done just after i bought it as i thought that might be the problem. It obviously hasn't solved or possibly the job wasnt done right.

If it was engine drivetrain connected would i be able to feel this thro the steering? As thats what it feels like. And what do u mean by imment dmf failure? It sounds expensive

DMF is dual mass flywheel and yes its £££.

Maybe also a bent driveshaft??? just maybe a thought

check the rear tyres for a bulge, had this on a previous car and the first thing the AA guy did was check the rear tyres for a bulge. asked him why the rear, he replied that low speed it be the front, high speed it be the rear.

Hope that helps/.

MDF failure usually makes itself felt at lower revs. I had a small vibration developing in my steering wheel at motorway speeds, which wasn't down to the balancing as it happened both before and after I had four new tyres fitted. The car was in for new console bushes, and the vibration has gone - in which case it was either the old, knackered bushes, or the alignment they did once they were fitted. New bushes are getting on for the sort of money a new DMF will cost you, once labour's factored in, but an alignment check might help if all else has failed?

(Not entirely sure why, but it worked for me! )
