Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent damage to driveline components. To check the mounts, the engine must be raised slightly to remove the weight from them. Begin by raising the vehicle and securely supporting it 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, raising the engine just enough to relieve the weight on the mounts without fully supporting the engine. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that rubber may split down the center. Applying rubber preservative or WD-40 can help slow deterioration. Check for any relative movement between the mount plates and the engine or frame using a large screwdriver or pry bar; if movement is detected, verify the tightness of the mount fasteners before deciding to replace the mounts, as broken mounts typically allow noticeable engine movement when pried or under load. To replace the mounts, disconnect the cable from the negative battery terminal, raise the vehicle and support it securely on jackstands, and remove both front wheels. Place a block of wood on a floor jack and position it under the oil pan. If replacing the left-side engine mount, remove the intermediate steering shaft, then raise the engine enough to relieve the weight on the mounts. Remove the engine mount through-bolt, then continue raising the engine until the mount is clear of the frame bracket and remove the mount-to-block bolts. Twist the mount until it comes free, and for installation, reverse the removal process, using non-hardening thread-locking compound on the mount fasteners and ensuring they are tightened to the specified torque.

Remove the bolts or nuts attaching it to the cross member and the transmission.

Installation follows the reverse order of removal, using non-hardening thread-locking compound on the mount bolts and ensuring they are tightened to the specified torque.

1. Disconnect the cable from the negative terminal of the battery. 2. Raise the vehicle and support it securely on jackstands. 3. For 4WD models, remove the interfering driveaxle. 4. If working on the left mount, remove the left inner fender splash shield and the exhaust manifold heat shield on most models. 5. Remove the engine mount-to-frame bracket bolts, noting that there are three bolts on each side securing the mounts to the frame bracket.

Applying rubber preservative or WD-40 can help slow deterioration.

Try to pry the transmission up slightly.
