Diagnosis And Testing: Vibration

WARNING: This page is about a different car, the 2004 Dodge Dakota and 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

Vibration at the rear of the vehicle is usually caused by:

Damaged drive shaft.
Missing drive shaft balance weight(s).
Worn or out of balance wheels.
Loose wheel lug nuts.
Worn U-joints or C/V joints.
Loose/broken springs.
Damaged axle shaft bearing(s).
Loose pinion gear nut.
Excessive pinion yoke run out.
Bent axle shaft(s).

Check for loose or damaged front end components or engine/transmission mounts. These components can contribute to what appears to be a rear end vibration. Do not overlook engine accessories, brackets and drive belts.
