Has anyone experienced any steering failures on this year(2002) Z-71. Mine has a real slight thump in the steering wheel when you cross a RR crossing/small pot holes. Steering on the highway is fine and the suspension is smooth on any other terrain. Seems to show up on small bumps in the road and at lower speeds.
Help please!! <img border="0" src=smileys/smiley11.gif border="0">

 

do you have high mileage? ever been in an accident?

 

Milage is 85,000. It's never been in a wreck, and I've owned it since it was new.
