National 710101 Drive Axle Shaft Seal - Front Inner

Drive Axle Shaft Seal for Front Inner Applications

National 710101 is a drive axle shaft seal built for front inner axle service on select Chevrolet and GMC 4x4 trucks and SUVs. It uses a nitrile sealing material and a bi-directional lip design to help maintain a consistent seal at the axle shaft interface.

Detailed Description

National 710101 is engineered as a front inner drive axle shaft seal for select 1988-1997 Chevrolet and GMC applications. The seal’s nitrile construction and bi-directional lip profile are specified to support sealing at the axle shaft while matching the listed housing bore, shaft diameter, and width dimensions. This makes it a practical replacement for service work on independent front suspension and AAM axle setups where the correct seal size is critical.

National has supplied sealing solutions for more than 75 years, and this part reflects that focus on dimensional accuracy and modern vehicle coverage. This part cross-references SKF 12320 for the same application. Search terms such as Chevrolet K1500 front inner axle seal, GMC Yukon drive axle shaft seal, and National 710101 oil seal align with this application.

Common Problems This Seal Can Address

• Gear oil leakage at the front inner axle shaft
• Contamination entering the axle housing through a worn seal
• Fluid seepage caused by hardened or damaged sealing lips
• Noise or driveline issues related to low axle lubricant level
• Service replacement for worn OE-style axle seals on 4x4 front axles

Installation Notes and Tips

Verify shaft diameter, housing bore, seal width, and axle design before installation. This seal is listed for front inner positions only, with fitment varying by axle type and ring gear configuration. Clean the bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Confirm the vehicle’s axle setup against the fitment notes for Chevrolet K1500, Chevrolet Tahoe, GMC K2500, and related models before final assembly.
