When a differential pinion seal starts weeping, the culprit is often a grooved, worn sealing surface on the rotating pinion yoke or companion flange — and the SKF Differential Pinion Repair Sleeve 99274 is designed to address exactly that. Rather than replacing the entire yoke, this repair sleeve installs over the damaged sealing surface to provide a fresh, smooth surface for a new pinion seal to ride against. No specific year/make/model applications are listed in our catalog for this part — match it using the interchange numbers below or your old part number.

This part cross-references / interchanges with the following part numbers:
What is a differential pinion repair sleeve?
It is a thin sleeve that installs over a worn or grooved sealing surface on the differential pinion yoke or flange, giving a new pinion seal a smooth surface to ride against instead of replacing the whole yoke.
How is it installed?
Repair sleeves are press-fit, driven squarely over the sealing surface of the pinion yoke or companion flange. Follow the vehicle service procedure and install it along with a new pinion seal.
Does this listing include a new pinion seal?
This listing is for the repair sleeve itself. A new differential pinion seal is normally installed with it, so order the correct seal separately if you need one.
Which vehicles does this fit?
No specific year, make, or model applications are listed in our catalog for this part. Match it using the interchange numbers or your original part number to confirm it fits your application.
What are signs the pinion sealing surface may need this?
A leaking or weeping differential pinion seal and a visibly scored or grooved sealing surface on the yoke may indicate a repair sleeve is needed. Diagnose the cause before ordering.
