How to remove and install a differential seal on GMC Yukon?

To remove and install a differential pinion seal, first loosen the wheel lug nuts and raise the front or rear of the vehicle on jackstands. Remove the wheels and disconnect the driveshaft from the differential pinion flange. Rotate the pinion and record the torque required to rotate it. Mark the relationship of the pinion flange to the shaft and count the number of exposed threads on the shaft. Use a special tool or chain wrench to immobilize the flange and remove the pinion nut. Withdraw the flange and pry out the old seal. Install the new seal by lubricating the lips and tapping it evenly into position. Apply RTV sealant to the ends of the splines visible in the center of the flange and install the washer and a new pinion nut. Tighten the nut until the recorded number of threads are exposed and measure the torque required to rotate the pinion. Tighten the nut in small increments until it matches the recorded figure and exceeds it by 5 in-lbs. Reinstall all components and tighten all fasteners to their specified torque values.

GMC Yukon Differential Seal

The purpose of the GMC Yukon Differential Seal is to stop the loss of gear oil and further prevent contaminants from accessing the differential gears. Located around the axle openings on the differential case, this Differential Seal retains lubricant in the case so torque-splitting gears can function while going straight and while cornering. When functioning properly, the Differential Seal prevents dust, water, and road debris from entering the housing so that the open or limited slip differential applied in a GMC Yukon works properly. The seal is typically molded from durable synthetic rubber. Various formulations of rubber are applied so the seal can withstand the pressure, friction, heat, and moisture in the vicinity of moving shafts. A worn or damaged Differential Seal will allow fluid to escape and lead to internal wear and noise. Therefore, drivers recommend replacing yours on any GMC Yukon the moment you see a leak or contamination. The new Differential Seal, if installed correctly, will help transmit power effectively and increase the life of the GMC Yukon's drivetrain.

Each OEM GMC Yukon 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.

A:

Remove the wheels and disconnect the driveshaft from the differential pinion flange. Rotate the pinion and record the torque required to rotate it. Mark the relationship of the pinion flange to the shaft and count the number of exposed threads on the shaft. Use a special tool or chain wrench to immobilize the flange and remove the pinion nut. Withdraw the flange and pry out the old seal. Install the new seal by lubricating the lips and tapping it evenly into position. Apply RTV sealant to the ends of the splines visible in the center of the flange and install the washer and a new pinion nut. Tighten the nut until the recorded number of threads are exposed and measure the torque required to rotate the pinion. Tighten the nut in small increments until it matches the recorded figure and exceeds it by 5 in-lbs. Reinstall all components and tighten all fasteners to their specified torque values.
