I'd actually do a visual inspection of the suspension and steering components and look for broken, loose, or worn parts... even a cracked frame. Then I'd wiggle, crimp, jostle the parts. Maybe even jack up the front end to cycle the suspension and steering. I'd probably even verify the the motor mounts are still in one piece.

I must be crazy.

2 or 4wd? Solid axle and you could have a death wobble going on.

If I had that going on in my truck, I think I'd have BOTH hands on the wheel!
