Oil seal
Replacement (On-vehicle)
Jack up the vehicle and support it with safety stands. Drain
the transaxle oil. Next, use the following procedure to replace
the driveshaft oil seal:
1. Remove the front wheel.
2. Remove the splash shield.
3. Separate the front stabilizer from the lower arm.
Caution
l Do not damage the dust boots.
4. Remove the clinch bolt and pull the lower arm downward.
Separate the knuckle from the lower arm ball joint.
5. Loosen the nut and disconnect the tie-rod end with the SST.
Caution
l Do not subject the tripod joint to shock when remov-
ing the driveshaft.
6. Disconnect the driveshaft from the transaxle by prying with
a bar inserted between the outer ring and the transaxle.
7. Suspend the driveshaft with a rope.
