Powertrain mounts — check and replacement
1. Powertrain mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately or the added strain placed on driveline components may cause damage or wear.
Check
2. During the check, the engine (or transaxle) must be raised slightly to remove the weight from the mounts.
3. Raise the vehicle and support it securely on jack stands, then remove the splash shields under the engine and position a jack under the engine oil pan. Place a large block of wood between the jack and the oil pan, then carefully raise the engine just enough to take the weight off the mounts. Do not position the wood block under the oil drain plug.
Warning: DO NOT place any part of your body under the engine when it is supported only by a jack!
4. Check the mounts to see if the rubber is cracked, hardened or separated from the bushing in the center of the mount.
5. Check for relative movement between the mount plates and the engine or frame (use a large screwdriver or pry bar to attempt to move the mounts). If movement is noted, lower the engine and tighten the mount fasteners.
6. Rubber preservative should be applied to the mounts to slow deterioration.
Replacement
7. Disconnect the cable from the negative battery terminal (see Engine electrical systems), then raise the vehicle and support it securely on jack stands, if not already done. Support the engine as described in Step 3. Note: If several mounts need replacement, only replace one at a time and tighten them as you go. Do not remove all the mounts at once.

9. Remove the bolts securing the mount to the frame, then raise the transaxle enough to allow removal of the mount.
10. Installation is the reverse of the removal. Use thread-locking compound on the bolts and be sure to tighten them securely.
