Ford E8TZ-6038-F Insulator Assembly

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage to driveline components. During the check, the engine must be raised slightly to remove the weight from the mounts. Begin by raising the vehicle and supporting it securely on jackstands, then position a jack under the engine oil pan with a large block of wood between the jack head and the oil pan, carefully raising the engine just enough to relieve the weight on the mounts. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine, transmission, or frame/body using a large screwdriver or prybar; if excess movement is observed, new mount isolators will be necessary. For front mount replacement, raise the vehicle and secure it on jackstands, then place a wood block and a jack under the engine. Remove the upper and lower nut and washer assemblies from the insulator assembly, and raise the engine just enough to allow clearance for the removal of the mount insulator and heat shield if equipped, with installation being the reverse of removal. For the rear transmission mount replacement procedure, additional guidance is available.

To check the transmission mount, raise the vehicle and support it securely on jackstands. Insert a large screwdriver or prybar between the transmission extension housing and the frame crossmember and pry up to check for excessive looseness. The transmission should not move significantly away from the insulator. If it does, the mount should be replaced. If the mount is okay, remove the jackstands and lower the vehicle. For early 4WO models, remove the lower insulator retainers and insulators, then remove the insulator bolts. Place a jack under the transmission and raise it enough to remove the upper insulators between the transmission bracket and crossmember. Install new upper insulators with the protruding shoulder facing down through the crossmember. Lower the transmission and install the insulator bolts, tightening the lower insulator retainer assemblies to the specified torque. Remove the jackstands and lower the vehicle, then test drive to confirm proper operation. For all other models, remove the mount-to-cross-member nuts and mount-to-transmission bolts. Place a jack under the transmission and raise it enough to remove the mount. Install a new mount and lower the transmission enough to start all fasteners hand tight. Remove the jack and tighten the mount fasteners to the specified torque. Remove the jackstands and lower the vehicle.

If the mount is okay, remove the jackstands and lower the vehicle.
