Buick 24288437 Axle Seal

This procedure does not apply to the transfer case seals on the right side of AWD models. Oil leaks frequently occur due to wear of the wheel seals, and replacement of these seals is relatively easy since the repairs can be performed without removing the transaxle from the vehicle. The seals are located on the sides of the transaxle where the driveaxles are attached. If leakage of a 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. Remove the driveaxle, noting how deep the seal is installed, then use a screwdriver to carefully pry the seal from its bore. If it can't be removed with a screwdriver, a special seal removal tool (available at most auto supply stores) will be needed. Compare the old seal to the new one to ensure it's correct, then coat the inside and outside diameters of the new seal with transaxle fluid. Using a seal installation tool or a large socket, install the new seal, driving it into the bore squarely and ensuring it's seated to its original depth. Install the driveaxle, and the installation is the reverse of removal. Check the transaxle fluid level, adding if necessary.
