Dorman - HELP Differential Crush Sleeve P/N:81057
Help set pinion bearing preload when you rebuild or reseal the axle with the Dorman - HELP Differential Crush Sleeve 81055, a pinion crush sleeve built to fit and work like the original sleeve. It fits many vehicles, among them the 1994-1996 Dodge Ram 1500, 1994-1996 Dodge Ram 2500 and 1987-2003 Dodge Dakota. See the Buyer's Guide tab for the full list and engine details.
A crush sleeve sits on the pinion shaft between the pinion bearings. As the pinion nut is tightened, the sleeve collapses in a controlled way, which helps hold the bearings at the preload the service procedure calls for. This sleeve is cataloged for both front and rear differential applications.
A crush sleeve that has already been compressed is not meant to be reused, so plan on a fresh one each time the differential is serviced. Follow the vehicle service information for the pinion nut torque and bearing preload specification.

What does a differential crush sleeve do?
It sits on the pinion shaft between the pinion bearings and collapses as the pinion nut is tightened. This helps hold the bearing preload set by the service procedure.
Why replace the crush sleeve when servicing the differential?
Dorman lists this sleeve as a required replacement when the differential is serviced. A sleeve that has already been crushed is not meant to be reused.
Does it fit my 1994-1996 Dodge Ram 1500?
Yes. The 1994-1996 Dodge Ram 1500 is one of its listed applications, along with the 1994-1996 Dodge Ram 2500. Check the Buyer's Guide tab to confirm your exact vehicle.
What should I know before installing it?
Install it as directed by the vehicle service information. Tighten the pinion nut gradually until the specified bearing preload is reached, because overtightening can over-crush the sleeve.
What signs may point to differential service?
Whining or howling from the axle, play at the pinion yoke, or a leak at the pinion seal may mean the differential needs service. Diagnose the cause before replacing parts.
