National 711046 Drive Axle Shaft Seal - Front
Drive Axle Shaft Seal for OE-Style Driveline Service
National 711046 is a metric drive axle shaft seal built for driveline and axle sealing applications where a precise housing bore and shaft fit matter. It uses nitrile material and a bi-directional lip design to help maintain a consistent seal at the axle shaft interface.
Compatible With Mopar applications that use the same OE-style dimensions, this seal is sized for a 3.150 in. housing bore, 3.158 in. outside diameter, and 1.969 in. shaft diameter. The National 711046 is a practical choice for axle seal replacement on vehicles such as Dodge Ram and Jeep models when the original seal matches these specifications.

Detailed Product Description
National has supplied sealing solutions for more than 75 years, and the 711046 reflects that focus with a drive axle shaft seal engineered around exact dimensional control. The seal is identified as an oil seal in the 711000 series and uses a Type 40 profile with a 0.689 in. overall width including the side lip. For axle service, the nitrile sealing material and bi-directional lip design help support a stable seal at the shaft and housing interface.
This part cross-references Mopar 68034432AA for the same application. When replacing a leaking axle seal on Dodge Ram or Jeep driveline assemblies, matching the housing bore, shaft size, and seal width is essential for proper service results. National 711046 is built for that kind of exact-match repair.
Common Problems This Seal Can Address
- Gear oil seepage at the drive axle shaft
- Fluid leakage around the axle housing bore
- Seal wear from age, heat, or contamination
- Noise or driveline concerns caused by low lubricant level
- Repeat leaks after an incorrect-size seal installation
Installation Notes and Tips
Verify the housing bore, shaft diameter, and seal width before installation. Clean the bore and shaft sealing surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Use proper installation tools to seat the seal evenly and avoid distorting the lip or outer case.
