How to replace a differential seal on Chevrolet Caprice?

Place the vehicle over an inspection pit or raise the rear end to provide adequate working clearance. Disconnect the driveshaft and tie it to the body sideframe. Using a torque wrench, check the torque required to rotate the pinion and record this for use later. Scribe or punch alignment marks on the pinion stem, nut, and flange for reassembly. Count the number of threads visible between the end of the nut and the end of the pinion stem and record for use later. Use a suitable tool to hold the pinion flange still while removing the self-locking pinion nut. Unscrew and remove the pinion nut. Withdraw the companion flange using a two or three-legged extractor if necessary. Pry out the old seal and discard it. Lubricate the lips of a new seal with extreme pressure lithium-based grease and tap it into position. Align the mating marks and install the companion flange, using a spacer if needed. Apply a non-hardening gasket sealer on the ends of the splines in the center of the companion flange. Install the thrust-washer and nut, tightening carefully to expose the original number of threads. Measure the torque required to rotate the pinion and tighten the nut slightly until it matches the recorded figure. To compensate for the new oil seal, further tighten the nut so that the rotational torque of the pinion exceeds the recorded value by 1 to 5 in-lb. Reconnect the driveshaft, install the brake drum and wheel, and lower the vehicle.

Chevrolet Caprice Differential Seal

The main function of Chevrolet Caprice Differential Seal is to lock in the gear oil and block dirt to keep the differential lubricated and healthy. Seated where the axle meets the housing, the Differential Seal creates a tight rubber seal to prevent precious 75W-90 lubricant from seeping out while keeping dust, water, and grit from the road out of the finely machined gears. When a worn Differential Seal fails, oil leaks out, heat builds up, and the gears that allow the rear wheels to turn at different speeds around sharp turns can quickly grind themselves to a point of no return. Over the years, the venerable Chevrolet full-size Caprice has carried both open and limited-slip differentials, and despite the fact that their internal torque-splitting hardware is different, both use the same style of Differential Seal to maintain fluid volume. Most factory seals are made of synthetic rubber designed for long life in hot, high-pressure applications, but there are variations, ranging from nitrile blends that are resistant to petroleum breakdown to high-temp silicone composites for severe duty. Original-equipment parts fit the housing to exact tolerances, but specialized performance versions may include flanged lips or protective bore coatings for added stability. Either type must seat flush for the Differential Seal to perform without leaks. Routine checks for seepage around the Caprice rear cover and prompt replacement keep the Chevrolet drivetrain quiet, cool, and dependable.

Each OEM Chevrolet Caprice Differential Seal we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
