I've had problems with a clunk in my steering wheel over bumps. Can't hear it, but I can feel it. I've had it for the past few months, and it was progressively getting worse. Checked the front end out, and all 4 ball joints were showing some wear, the passenger side inner and outer tierod ends were shot, and so was my track bar. Replaced everything but the track bar a couple months ago, and still had the clunk. Just put a 3rd gen. adjustable trackbar on last week, and it seemed to get better, but could still feel it once in awhile. Well the past few days its really gotten bad... I feel it over every little bump, when the weight of the truck shifts back after coming to a stop, and when I'm accelerating, shift gears, and get back on the throttle. I kinda doubt that the control arm bushings are shot at 80,000miles, but I'm kinda leaning towards it being the steering shaft or the lower bushing in the steering columb? Any ideas? if it does turn out to be my steering shaft, who has the Borgeson shaft the cheapest?
