Diagnosis And Testing: Vibration

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. 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 a:

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

All driveline components should be examined before starting any repair.
