Detailed Description
National 710649 is a metric wheel seal in the 710600 series, engineered for rear inner positions on Toyota Tundra, Tacoma, and 4Runner applications listed above.

What This Seal Helps Address
- Gear oil leakage at the rear inner wheel seal area
- Contamination entering the hub or axle sealing surface
- Seal wear from heat, rotation, and age
- Moisture intrusion around the axle seal interface
- Loss of sealing integrity on Toyota rear axle service work
Installation Notes and Tips
Verify shaft diameter, housing bore, and seal orientation before installation. Clean the sealing surface and inspect the axle or hub for grooves, corrosion, or damage that can affect seal life. Confirm the rear inner position on the vehicle and match the seal dimensions to the service specification before assembly.
