I didn't re-read everything here, but in mine I replaced the hub...errr whatever you can non-manual/non-automatic, but still not a wheel-bearing thingy. Either way it was $200 and the noise stopped. My hard pull was not found, but fixed by replaceing my brakes. Did the parking brake in an hour or two, no problems, working nice. I have a vibration over 70mph, steering pulls a little bit right, 4wd still messed up, but it's prolly the shift motor.
GOing to put on BL, do the ball-joints, new tires, and alignment and see where I stand.
The play in my steering, where my vehicle wanders is either ball-joints, The connection of the steering through the firewall, or worse yet, the rack and pinion, yes, I believe we have it.
As described in other posts, most people with those problems felt HARD steering one way and easy or normall the other. I've mentioned rack and pinion everytime I talk to people and it's iqnored, even though I've read it's easy to damage. If it's so easy, then I would think a "good" off-roading trip could mess it up something good, but I don't have that much experience.
