SKF Axle Differential Bearing and Seal Kit P/N:SDK321
SKF SDK321-CMK rear axle differential bearing and seal kit for the 1999-2002 Chevrolet Silverado 1500 and other vehicles replaces the bearings and seals inside a worn differential.
A whine or howl from the rear axle, or a leak around a differential seal, can mean the differential bearings or seals are worn, though a worn axle shaft bearing or a worn gear set can be behind the same signs.
The 2002-2006 Chevrolet Trailblazer and the 1999-2002 GMC Sierra 1500 are among the other vehicles it fits, and each takes one kit. Open the "Vehicles it fits" section and look up your exact model and engine.
