Oil leaks frequently occur due to wear of the wheel seals, and replacement of these seals is relatively easy since the repair can be performed without removing the transaxle from the vehicle. Wheel seals are located at the sides of the transaxle, where the driveaxles are attached. If leakage at the seal is suspected, raise the vehicle and support it securely on jackstands; lubricant will be found on the sides of the transaxle, below the seals if the seal is leaking. Begin by removing the driveaxles, then use a screwdriver or prybar to carefully pry the seal out of the transaxle bore. If the seal cannot be removed with these tools, a special seal removal tool, available at auto parts stores, will be required. To install the new seal, use a large section of pipe or a large deep socket, slightly smaller than the outside diameter of the seal, as a drift. Drive it into the bore squarely and ensure it is completely seated, coating the seal lip with transaxle lubricant. Finally, install the driveaxle(s), taking care not to damage the lip of the new seal with the inboard splines of the driveaxle.
