Q: How to replace driveaxle oil seals in Automatic transaxle for Chevrolet Cobalt,HHR,Pontiac G5 and Saturn ION?
A: Wheel leaks frequently occur due to wear of the wheel seals. Replacement of these seals is relatively easy since the repairs can be performed without removing the transaxle from the vehicle. The wheel seals are located on 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. If the seal is leaking, fluid will be found on the sides of the transaxle. To remove the left-side seal, remove the snap-ring on the stub shaft and use a screwdriver or seal removal tool to carefully pry the wheel seal out of the transaxle bore. Measure the distance that the stub axle protrudes beyond the sleeve and remove the sleeve from the stub shaft using a special puller. Compare the old seal to the new one to ensure it's the correct one. For installation, coat the new seal with transmission fluid and use a seal installation tool to drive it into the bore. Use a special tool to press the new sleeve onto the stub shaft and install a new snap-ring on the stub shaft before installing the driveaxle.
