Why does my 1996 Jeep Grand Cherokee shake severely when I hit a bump?

Answer 1

Have your tires balanced.

Possibly rotate if it has not been done within the last 5000 miles.

Check tires to see if they are choppy. (This will be extremely annoying however it is not a safety issue.)

Check air pressures to see if they are correct. (Manufacture air pressures can be found within the door jam of your (most) vehicle(s).)

Answer 2

The most common problem is a defective steering dampner. You could also have a bad idler or pitman arm, Centerlink or ball joints.
