'97 Sierra 1500 4x4, 90K miles, good, new tires. The lugnuts are tight. When I start a gradual right turn, at slow speed, I suddenly get a slight softness in the steering wheel, and a little more vehicle turn than should happen - requiring a slight correction to the left. Doesn't happen every time, but often. I think it might be getting worse
- beginning to happen with left turns also, and at higher speeds. Does anybody recognize the symptom, and what to do about it? Thanks, Cal
