Hello,
I have been trying in vain for nearly 18 months now to resolve a steering wheel wobble problem on a 2002 A6 2.7T Quattro. The wheel never wobbles below 45 MPH or above 55 MPH. At 50 MPH the wheel will wobble back and forth by as much as a half inch in each direction, then stop and be solid as a rock for 30 seconds then start wobbling again. There seems to be no consistent correlation with road surface either. What has been tried so far:
1) Brand New tires (3 different sets) 2) Brand New wheels (2 different sets) 3) Alignment (10+ times) 4) Wheel balancing (20+ times by 5 different shops) 5) New tie rod ends, ball joints and wheel bearings 6) New steering rackNone of these things has made the slightest bit of difference and every mechanic agrees that they can see the problem, but cannot for the life of themselves figure out what is causing it.
Someone please HELP!
