What causes violent wheel wobble when hitting a bump?

I would suspect either a loose wheel, or worn suspension or steering parts. This is very dangerous. Have the steering & suspension inspected.

Answer

I have a 1997 dodge 3/4 ton, my pickup was shaking real bad when I would hit a bump so I replaced the "steering shock" I do not know if that is what it is called but it is the shock on the front of the vehicle. Replace it and that should fix the problem.

Answer

This is a very common problem on 2nd generation 4x4s, Don't use a stock steering shock get a heavy duty after market one. Another good fix is a Luke's Link, check the link at the side for more information it has great diagrams and instructions to fix the track bar.

Get a Bilstein Steering Shock. The problem will most likely go away. I've had 2 RRC's and I did this fix myself on both cars.
