How to replace the rear Differential Seal on Chevrolet Blazer?

To remove the rear wheel, start by loosening the lug nuts and raising the rear of the vehicle on jackstands. Disconnect the driveshaft and secure it out of the way. Use an inch-pound torque wrench to check the torque required to rotate the pinion on semi-floating axles and record the reading. Make alignment marks on the pinion shaft, nut, and flange, and count the number of threads visible between the nut and shaft. Use a special tool or large pliers to loosen the self-locking pinion nut. Remove the nut and withdraw the companion flange, using a puller if necessary. Pry out the old seal and discard it. Lubricate the new seal and tap it into position with a seal installation tool or large socket. To install, align the mating marks and install the companion flange, tightening the pinion nut if needed. Apply non-hardening sealant to the spline ends on the flange. Install the washer and pinion nut, tightening it until the original number of threads are exposed. Measure the torque required to rotate the pinion and tighten the nut incrementally until it matches the recorded figure, slightly exceeding it to compensate for the new oil seal. Connect the driveshaft, install the wheels, and lower the vehicle, tightening the lug nuts to the proper torque.

Chevrolet Blazer Differential Seal

The Chevrolet Blazer Differential Seal is one of the components of the axle that keeps the gear oil inside the axle housing. It also prevents dirt from getting into the axle. This guarantees a smooth transfer of torque through the differential. A ring of heat resistant synthetic rubber or rubber metal composite is fitted around pinion or axle shafts so the important lubricant does not leak out in open differentials or limited slip differentials. Whether located up front, at the rear, or nestled between axles (as on four wheel drive versions), the Differential Seal performs the same task, keeping the lubricant where the gears need it. Contemporary modifications include reinforcing ribs, flanges, or specialized bore coatings that stabilize the Differential Seal at increased pressure while still maintaining compliance with factory Chevrolet specifications for easy press fit during servicing. Routine inspections at intervals of 3,000 miles, as well as a prompt reaction to unusual clanking or rattling noises, help drivers detect a failing Differential Seal before low fluid damages the gear set. Should it be required, a Differential Seal replacement can be done without removing the entire axle, and many Blazer owners will appreciate this. It keeps the Blazer rolling along with the reliable Chevrolet drivetrain for the next corner.

Each OEM Chevrolet Blazer 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.
