Steering wheel shake/shudder at different speeds
Can someone help with diagnosing this problem.
2001 BMW 540i
My steering wheel shakes/shudders at speeds of 75-80kph then again at 110kph and 160kph.
If I slowly accelerate up to to 70-80kph I feel the vibration, If I quick accelerate up to 70-80kph I dont feel the vibration.
Sometimes I get no vibration, and sometimes I get alot. If im declerating from say 120-130kph down to about 70kph I get the shudder and vibration while braking.
Below 70kph I feel no vibration.
Got the wheels balanced, upper control arms and ball joints replaced. Tie Rod assembly replaced. And got an allignment, but nothing worked.
I still have the vibration.
Please advise. Thanks
