Hey Ray,
I have a '98 Suburban 1500 and have the same exact issue but it happens when I'm turning right. If you find out what is causing this please post. My steering wheel has also begun to stick when turning left.-- When I turn left, the steering wheel stays in that location, it does not return to it's original postion so I have to steer it back to going straight. Literally, if I turn left and then take my hand off of the wheel, I will just go in circles. Any thoughts or experience with this would be much appreciated.
Thanks,
Enoch
