The steering wheel shakes at highway speeds (at exactly 90kmh) and gets progressively more violent with higher speeds. Anything past 110kmh is undriveable.
The strange thing is that it appears to be intermittent. The wheel will be still at times, and then start shaking again. for a short period (usually after I hit a bump), then "level off" and be still until the next bump.
I have replaced:
1) Inner tie rod ends with Moogs
2) Outer tie rod ends
3) LCA bushings with Prothanes
4) Tires balances and aligned
I have checked ball joints as per the FSM, both sides appear fine.
Any ideas, because I'm all out...
