2001, 4X4, I have replaced the ball joints recently, the track bar, added a DSS and it goes down the road pretty good but lately I have been able to feel bumps and variances in the road back through the wheel. Yestrerday I noticed when I am driving slow on a rough road and let go of the steering wheel, I can see the wheel move as it goes over little ruts and ridges. Could this be the steering stabilizer or some other weird second gen thing. I have almost 200,000 on my first gens and the steering is still very tight.
