Jeep 68183993AB Engine Mount Insulator

To check the mounts, the engine must be raised slightly to relieve weight from them. Begin by raising the vehicle and securely supporting it on jackstands. Then, remove the front wheels and tires. Position two jacks, one under the crankshaft pulley and the other under the transaxle bellhousing, using a block of wood to protect the components while raising the engine/transaxle just enough to relieve the mounts. Inspect the mounts for any cracks, hardened rubber, or separation from the metal sleeve, and check for any relative movement between the mount bracket and the engine, subframe, or chassis using a large screwdriver or prybar.

For the front mount replacement, support the engine with a block of wood under the oil pan. Remove the splash shield. Take out the front mount through-bolt and crossmember-to-mount bolts before removing the mount itself. If the mount bracket needs replacement, remove the bracket-to-block bolts. Installation follows the reverse order, ensuring all fasteners are tightened to specified torque values.
