To replace the axle seals in your Volkswagen, start with gathering tools like a socket wrench set and torque wrench to handle bolts with precision. Lift and secure the vehicle using a hydraulic jack and jack stands, referring to the Volkswagen Service Manual for correct jack points. With the axle exposed, carefully loosen lug nuts and axle nuts, supporting the axle during removal. For seal installation, ensure the surface is clean, apply sealant if needed, and press the new seals flush with the housing.
