National 711064 Drive Axle Shaft Seal - Rear

Drive Axle Shaft Seal for Rear Differential Service

The National 711064 drive axle shaft seal is a metric oil seal built for rear driveline applications that require a precise seal at the axle shaft. It uses a bi-directional lip design and fluoro-elastomer material to help maintain sealing performance in demanding differential environments.

Compatible with rear applications on Cadillac ATS, Cadillac CTS, Buick Enclave, Buick Envision, Chevrolet Equinox, Chevrolet Traverse, GMC Terrain, GMC Acadia, Chevrolet Captiva Sport, Saturn Outlook, Saturn Vue, and Pontiac Torrent where the listed differential and axle specifications match. National 711064 is a direct-fit style seal for vehicles using a 35 mm shaft and 49 mm housing bore dimensions.

Key Features

• Drive axle shaft seal for rear differential service
• Bi-directional lip design for sealing in either rotational direction
• Fluoro-elastomer construction for durability in oil-seal applications
• Metric dimensions: 35.000 mm shaft, 49.000 mm housing bore
• Outside diameter: 49.200 mm; width: 15.500 mm
• Oil seal design for driveline and axle sealing systems
• National 711064 and 711064 are the part number references for this application

Detailed Description

National 711064 is part of the 711000 series and is engineered as a rear drive axle shaft oil seal for vehicles equipped with the specified ring gear and differential setups. The seal’s bi-directional lip design helps maintain contact at the shaft interface, while the fluoro-elastomer material is selected for sealing performance in oil-exposed driveline service. This makes it a practical replacement for rear axle sealing on GM and related crossover platforms, including Chevrolet Equinox, GMC Terrain, and Buick Enclave applications listed in the fitment data.

This part cross-references SKF 13544A for the same application.

What It Helps Fix

• Rear differential oil seepage at the axle shaft
• Fluid loss around the axle seal area
• Contamination entering the differential through a worn seal
• Noise or driveline concerns caused by low differential fluid level
• Seal wear from age, heat, and fluid exposure

Installation Notes and Tips

• Verify the housing bore, shaft diameter, and seal width before installation.
• Inspect the axle shaft surface for grooves or corrosion that can affect sealing.
• Clean the bore and sealing surface thoroughly before pressing in the new seal.
• Confirm rear differential configuration, including the listed ring gear and axle type, before ordering.
• Use the vehicle-specific fitment data for 2018-2007 applications to match the correct rear axle setup.

Quality Assurance

National has supplied sealing solutions for more than 75 years and continues to develop designs for modern vehicle service needs. The 711064 reflects that focus with a metric oil seal construction intended for consistent driveline sealing performance.
