Detailed Description

SKF Speedi-Sleeve 99171 is engineered to restore a scored or worn pinion shaft sealing surface quickly and accurately. Instead of removing the shaft for machining, the sleeve creates a new outer sealing surface that works with the existing seal size. This makes it a practical repair solution for front differential service on 2000-2010 Dodge Dakota, 2000-2009 Dodge Durango, 2007-2009 Chrysler Aspen, 2006-2009 Mitsubishi Raider, and 2011 Ram Dakota applications. This part cross-references Chrysler (e.g., 975999171) for the same application.

What It Helps Fix

• Oil seepage at a worn differential pinion shaft sealing surface
• Grooves or scoring on the shaft where the seal rides
• Repeat seal failure caused by shaft wear
• Time-consuming shaft regrinding or refinishing
• Front differential service issues on Dakota, Durango, Aspen, and Raider models

Installation Notes and Tips

Install the sleeve over the worn sealing area and use the supplied tool to seat it correctly. The design allows installation without removing the shaft and without changing seal size. Verify the shaft diameter is 1.718 in before ordering, and confirm front-position application for your vehicle.
