Installation Notes and Tips

Inspect the sealing surface, shaft condition, and housing bore before installation. Clean the area thoroughly and verify the old seal is fully removed before pressing in the new Timken 710535 seal. Use proper installation tools to avoid distorting the seal case or lip. Confirm the transmission application and year match the vehicle before service, including Ford Explorer Sport Trac, Ford Thunderbird, Lincoln Aviator, Mazda B2500, and Mercury Mountaineer listings where applicable.
