You can Select Your Vehicle to check if 11320-ZZ50B fits your vehicle.

Installation follows the reverse order of removal. Ensure the metal heat shield is in place between the insulator and the engine bracket, apply thread locking compound to the mount nuts before installation, and tighten them to the specified torque.

Insert a large screwdriver or prybar into the space between the transmission extension housing and the crossmember. Attempt to pry the transmission up slightly; it should not move much at all, indicating that the mount is intact.

To check the mounts, the engine must be raised slightly to remove the weight from them. The vehicle should be securely supported on jackstands, with the engine/transmission supported from above using a hoist or three-bar support fixture. Inspect the mounts for any cracks, hardening, or separation of the rubber from the bushing, and check for relative movement between the mounts and the engine or frame using a large screwdriver or prybar. If movement is detected, lower the engine and tighten the mount fasteners.
