On certain sport utility vehicles and pickup trucks equipped with four-wheel drive (4X4), if moisture leaks into the front suspension upper ball joint, evacuation of the lubricant and corrosion of the joint may cause the joint to wear over an extended period of time. This could cause a clunking noise in the front suspension, which may not always be heard by the vehicle occupants.
Dealers will replace the front suspension upper ball joints. This safety improvement campaign began on December 21, 2004. Owners can contact DaimlerChrysler at 1-800-853-1403.
