Renew a worn differential pinion sealing surface instead of scrapping the yoke with the SKF Differential Pinion Repair Sleeve, part number 99171. Once a pinion seal wears a groove into the shaft or yoke it rides on, a fresh seal alone tends to keep weeping — this thin-wall sleeve presses over the damaged area to give the seal a new, smooth surface to run against.
Signs the sealing surface may need this sleeve include gear-oil seepage at the pinion and a visible wear groove where the seal lip contacts the shaft. If a worn shaft surface is the cause of your leak, this sleeve renews it. Because a repair sleeve is sized to a specific sealing surface, match the sleeve dimensions to your pinion seal area before ordering.

Manufacturer part number 99171
This part cross-references / interchanges with the following part numbers:
What does the SKF 99171 pinion repair sleeve do?
It's a thin-wall sleeve that presses over the worn sealing surface on the differential pinion shaft or yoke, giving the pinion oil seal a fresh, smooth surface to ride on.
Do I need a new pinion seal too?
Yes — install the sleeve together with a new differential pinion seal. The sleeve renews the shaft surface, and the new seal rides on it for a proper repair.
How does the sleeve install?
It's press-fit — driven squarely over the shaft or yoke sealing area. No machining is required, and you don't have to replace the entire pinion yoke or flange.
What are the signs I need this sleeve?
Gear-oil seepage at the pinion and a visible groove worn into the shaft where the seal lip contacts it. Diagnose the cause of the leak before replacing parts.
What vehicles does part 99171 fit?
No specific vehicle fitment is listed for this repair sleeve. It is sized to a sealing surface, so match the sleeve's dimensions to your pinion seal area before ordering.
