REAR MAIN OIL SEAL | REPLACEMENT

1. Remove the transaxle (see Chapter 7).
2. Remove the driveplate (see Section 15).
3. Inspect the oil seal, as well as the oil pan and engine block surface for signs of wear. Sometimes an oil pan gasket leak can appear to be a rear oil seal leak.
4. Pry the oil seal from the block with a screwdriver. Be careful not to nick or scratch the crankshaft or the seal bore. Thoroughly clean the seal bore in the block with a shop towel. Remove all traces of oil and dirt.
5. Lubricate the lips of the new seal with engine oil or multi[purpose grease. Install the seal over the end of the crankshaft (make sure the lips of the seal point toward the engine) and carefully tap it into place. A special aftermarket tool may be available at your auto parts store. The tool just fits the diameter of the seal and, used with a hammer, drives the seal in. NOTE: Do not drive it in any farther than the original seal was installed.
6. Install the drive plate.
7. Install the transaxle.

POWERTRAIN MOUNTS | CHECK AND REPLACEMENT

1. Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately or the added strain placed on the driveline components may cause damage or wear.
2. During the check, the engine must be raised slightly to remove the weight from the mounts.
3. Raise the vehicle and support it securely on jackstands. Place a large block of wood between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts.
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 mounts and the engine or frame (use a large screwdriver or pry bar to attempt to move the mounts).
6. If movement is noted, lower the engine and tighten the mount fasteners.
REPLACEMENT
7. Disconnect the cable from the negative terminal of the battery (see Chapter 5), then raise the vehicle and support it securely on jackstands.
8. Remove the right front wheel and the inner fender splash shield (see Chapter 11).
9. Place a large block of wood between the jack head and the oil pan, then carefully raise the engine just enough to take the weight off the mounts. NOTE: Do not disconnect more than one mount at a time unless the engine will be removed from the vehicle.
10. Remove the engine nuts and detach the mount from the chassis bracket.
11. Remove the nuts holding the mount to the engine bracket.
12. Installation is the reverse of removal. Use thread-locking compound on the mount bolts and be sure to tighten them securely.
13. Reconnect the battery.
