Can running two different offset wheels on the rear be the reason im getting vibration when accelerating above 90? Been chasing this vibration for a while now its starting to do my head in Link to comment Share on other sites More sharing options...

Tailshafts bolt up to the diff 1 way only. Link to comment Share on other sites More sharing options...

Might have a look at the wheel bearings and check the runout. Thanks for your thoughts. Wish me luck Link to comment Share on other sites More sharing options...

The vibration is upon acceleration only. Not deceleration or when coasting. If it was a wheel balance or bearing problem wouldnt throttle position have nothing to do with it?
