I just pointed a vid camera under my front end. Don't turn on the engine and turn the wheel a little side to side, not so much to move the tires, but just to start moving the steering gear against itself. Any movement you see is too much. Check the tie rod ends, track bar, drag link. Turn on the motor and check the ps pump, too (mine was a little loose because of me). Then jack up the wheels and check the ball joints. Your control arms may be loose too. I think that's about it, except the tire issues. Also, imo the steering stabilizer is to dampen steering feedback from the trail, not from your rig. It seems like half the world thinks they were invented to stop death wobble, although I'll admit I've never had a set of tires that wouldn't balance.
