Hey, I just bought a 2009 XR6 with 190xxx kms. I’m getting a vibration through the steering wheel above 70km/h, which increases with speed.
Still vibrates when cruising above this speed in neutral.
Got a wheel balance and alignment after finding out the LF was toe’d out by 5mm. Still have the vibration.
What could be the cause? I’m thinking if it’s not a bent rim or cooked tyre then maybe the control arm bushes or maybe rotors?
Any suggestions would be great - no time to fix it myself so I have to present this issue to a mechanic also.
