Fluid leaks frequently occur due to wear of the driveaxle oil seals or the speed sensor O-rings. Replacement of these seals is relatively easy, since the repairs can usually be performed without removing the transaxle from the vehicle. The driveaxle oil seals are located on either side of the transaxle, where the drive-axle shaft is splined into the differential. If leakage at the seal is suspected, raise the vehicle and support it securely on jackstands. If the seal is leaking, fluid will be found on the side of the transaxle. To replace the driveaxle seal, remove the driveaxle and carefully pry out the old seal using a screwdriver or prybar. If necessary, a special oil seal removal tool can be used. Install the new oil seal using a seal driver or a large deep socket as a drift, making sure it is completely seated and lubricating the lip with multi-purpose grease. For speed sensors on 5-speed transaxles, look for lubricant around the sensor housings to determine if an O-ring is leaking. Disconnect the electrical connector and remove the sensor from the transaxle. Remove the old O-ring and install a new one on the driven gear housing before reinstalling the speedometer driven gear and vehicle speed sensor housing, tightening the hold-down bolt securely.

Leaks may happen because of wear of the wheel seals; replacing the seals is rather simple and does not require transaxle removal from a vehicle. These seals are mounted on the sides of the transaxle that is on the driveaxle shaft end connected to the differential. If the seal is leaking, fluid will be on the side of the transaxle for checking leakage, raise the vehicle and support it on jack stands securely. Starting with, strip the driveaxle, and if mending the right side driveaxle seal, then you need to also release the intermediate and the driveaxle assembly. Delicately remove the wheel seal off the transaxle bore using a screwdriver or prybar so you do not harm the surface of the seal bore. If it is challenging to get rid of the seal, then it is recommended that an oil seal removal tool is useful. When placing a new wheel seal, it can be punched into place with a seal driver or a large deep socket as a drift making sure that it is square and sets fully into the bore, while the lip of the new seal can be lubed with multi-purpose grease. Last not least, reinstall the driveaxle assembly but being very careful not to cause damage to the lip of the new seal you just installed.
