Detailed Description

SKF has a long history in seal design and manufacturing, and the 18701 reflects that focus with premium materials and application-specific construction. This differential pinion seal is made to maintain proper lubricant retention at the pinion area while helping block dirt, moisture, and other contaminants that can shorten axle life. It is a practical replacement for service work on Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, and Jeep Grand Cherokee rear or front axle assemblies where the listed dimensions and axle notes match.

This part cross-references 1C3Z4L616BA and 5072265AA for the same application. Use SKF 18701 when servicing Dana 60, Dana 70, Spicer 44, and select Spicer 60 axle configurations that call for this seal size and style.

What It Helps Address

• Gear oil seepage at the differential pinion area
• Contamination entering the axle housing through a worn seal
• Noise or wear concerns caused by low lubricant level
• Seal failure during axle service or differential rebuilds
• Maintenance on Dana 60, Dana 70, and Spicer axle assemblies

Installation Notes and Tips

Verify shaft diameter, outside diameter, and width before installation to confirm the seal matches the axle housing and pinion surface. Inspect the pinion yoke or flange sealing surface for grooves, corrosion, or damage before installing the new seal. Clean the bore thoroughly and install the seal squarely to avoid distortion. For best results, confirm the axle type and position against the vehicle listing before service.
