Oil leaks often result from worn seals or sensors. These can be replaced without removing the transaxle. If you spot lubricant puddles under the transaxle, lift the vehicle and place it on jack stands. Identify the leak source. For the extension housing oil seal, remove the driveshaft, heat shield, and seal. Install the new seal with a seal driver or large deep socket. For the Wheel Seal, remove the exhaust manifold and center exhaust pipe, place a drain pan under the transaxle, remove the driveaxles, and pry the Wheel Seal from the transaxle. Install the new seal, lightly oil it, and reinstall the driveaxles. Check and adjust the transaxle or differential lubricant level as needed.
