Description

Reassemble the pinion in your rear differential with a fresh Dorman - HELP Differential Crush Sleeve, part number 81058. This collapsible spacer compresses as the pinion nut is tightened, which helps set the preload on the pinion bearings. It fits many vehicles, among them the 1976-1985 Chevrolet Impala, 1978-1983 Chevrolet Malibu and 1982-2002 Chevrolet Camaro. See the Buyer's Guide tab for the full list.

Dorman lists this part as a pinion crush sleeve and designed it as a direct replacement for the original sleeve on the listed applications. A crush sleeve deforms permanently once it has been compressed, so a new one is called for whenever the differential is serviced.

Direct replacement: Designed to fit and work like the original sleeve on the specified vehicles.
Required replacement: A new sleeve is needed when servicing the differential.
Durable construction: Made from quality materials for durability and reliable performance.
Trustworthy quality: Supported by a team of product experts in the United States and more than a century of automotive experience.

During installation, follow the vehicle service information for pinion nut torque and bearing preload. Consult the service procedure for the correct pinion nut and seal, and for whether either may be reused.
