Engine Mount Inspection

Caution

Broken or deteriorated mounts can cause misalignment and destruction of certain drive train components. When a single mount breaks, the remaining mounts are subjected to abnormally high stresses.

1. Observe the engine movement at the engine mount in order to check for excessive movement of the mount. 1.1. Apply the parking brake. 1.2. Start the engine. 1.3. Firmly apply and hold the primary brakes. 1.4. Have an assistant stand to the side of the vehicle in order to observe for engine movement. 1.5. Slightly load the engine, shifting from drive to reverse a few times.
2. If the engine appears to have excessive movement from the rest position in any direction, check for loose, or missing engine mount bolts in the following locations: Engine mount to engine Engine mount bracket to frame Engine mount to engine mount bracket
