1996 Yukon Power Steering

[vesthj]

I have a 1996 Yukon with 4wd. When I turn the truck to the right, the power steering gets extremely tight. Meaning that I can turn the steering wheel just a little , the truck wants to turn alot, and the steering get very, very easy. This does not happen all the time. I can turn the truck off and it seems to reset itself. All will be fine for a while.

Any Ideas?

I had a similar problem w/my 97. GMC developed a variable power steeering pressure system to limit pressure a high speeds to reduce the lickelyhood of rollovers. Unfortunately, the system is seriously flawed. The vary the pressure of the system with a valve in the power steeeeering pump which is controlled electrically. What is probably happening is the control or the valve is screwed up. I got sick of it and disconnected the wires to the pump and installed a good old steering stabilizer shock and I love it. No more problems, smooth predictable steering. This is a classic example of GM messing with a good thing and causing problems.
Good Luck
