Hey fellas,
I have the same issue and haven't found a cure yet. Everyone mentions getting a steering damper, however I am quite sure this will only be a temporary fix until I figure out what's going on in the front suspension. Rather than invest in the steering damper and hope the issue resolves, I much rather start swapping the front suspension and correct the issue...then install the steering damper to prevent it.
Not knowing much about cars, does anyone have images that can help me locate all the steering components of the Yukon 01 and what they do. I do know the tie rods, however I am lost when it comes to all others such as the ones below.
Pitman arms
Idle arms
Ball joints
Bearings
U-Joint
Steering box
Control arm bushings
My Yukon does have sever Bump-Steer and it drives me crazy. Never did it before until about a year ago. I constantly check my alignment, balance, rotate, have new tie rods, get the suspension checked with all shops (Midas and Pepe Boys) and yet nothing
seems to work. If I could narrow down the items above while getting it fixed, that would help tremendously.
