Re: ed XR6 car shake!!!!!
Can you give more information?
Is it a thump, or is it a drumming sound. Is it worse when you apply the brakes?
Low frequency thumpimg could be tyres, or anything rotating at wheel speed. If it shakes when you apply the brakes, it could be warped discs. Out of balance tryes will make that noise, and if it's the front tyres, you'll feel it through the steering wheel. Same too with brake disc troubles.
A higher frequency drumming sound could be tailshaft out of balance.
Both of these types of sounds change when car speed changes.
Over to you!
