"only when not under load..ie if you put the clutch in to change gear.. when accelerating theres no vibration... when coasting in gear theres no vibration.. only for a second when u let go of the accel pedal"

Hey phunks.....basic physics may work...but they need to apply to the problem...

The problem occurs when NOT under load...when the clutch is ENGAGED..

Phunks you may be onto something with the wheels...I spose when under load the "vibration zone" would be passed quite quickly and thus the vibration may be less obvious..I spose this could also explain why you may be right about the unis...

But with the unis...I understood you saying the angle is caused by axle wind up???..if this is your theory then I spose it can't be the unis...this time!!!! as the problem occurs under no load..
