Known Problems

A fluid leak may develop from the transmission output shaft seal. This leak may cause the transmission mount to become oil soaked and require replacement of the mount along with the leak repair.

The outside door handles are prone to breaking—all doors are affected by this condition.

Timing gears may wear causing a mild to severe knocking noise from the front of the engine. Replacement of the timing gears is necessary.

The idler arm, pitman arm, or center steering link may wear and cause excess play in the steering. If any of these components are replaced, the front end alignment should be checked.
