can anyone tell me the what is wrong, wheel wobble never the same speed. It;s up and down the speed range.

Wheel out of balance

Tyre out of shape

Driveshaft out of balance

Poor fitting wheels

Gearbox

Cheers for that wondered if it could be struts

I would think to cause wheel wobble it will have to be something reciprocating,

Check the wheel bolts and the tyre profile. I have had tyres go off and it caused me some concern :(

My first thoughts would be wheel bolts, then tyre out of round, or a balance problem caused by getting some liquid inside the tyre.
