How to Replace a Differential Seal on a Subaru Outback?

To replace the rear differential pinion seal, raise the vehicle and support it on jack stands. Put the transaxle in Neutral, and the parking brake off. Measure the pinion flange's turning torque and note it. Remove the retaining nut and pinion flange, using a puller if needed. Detach the worn seal, and install a new one. Tighten the pinion flange nut to minimum torque, checking the turning torque against the noted figure. Reinstall the driveshaft and lower the vehicle.

Subaru Outback Differential Seal

The Subaru Outback Differential Seal is a simple but essential little part that keeps differential gears coated in oil while shutting out dirt. The seal keeps the power being delivered smooth and quiet. Each Differential Seal in a Subaru withstands heat, pressure, and axle motion without surrendering lubricant, which is located on the front, rear, and center assemblies. When intact, it lets open or limited slip differentials share torque so the wheels turn at different speeds, helping the Outback corner confidently. Made from state-of-the-art synthetic rubber, the standard Differential Seal has flexibility and chemical resistance to operate efficiently during your run-of-the-mill commutes. Performance versions with flanged lips and latex bore coatings keep the seals square in their housing and mask minor bore imperfections. When a Differential Seal fails, it can leave oily spots on the ground, create rattles upon engagement, whine at highway speed, and starve the gears of fluid. Ensure the car is noise- or leak-free every 3,000 miles. Top up fluids quickly and replace a worn-out Differential Seal before damage spreads, keeping the Outback driveline healthy and your trip worry-free. The risk is further reduced by following the Subaru maintenance schedule.

Our website stands as the go-to online destination for OEM Subaru Outback Differential Seal. With complete lines of genuine Subaru Outback Differential Seal available at unbeatable market prices, we ensure top quality, reliability, and durability. Each part comes backed by the manufacturer's warranty, reinforcing your trust in our offerings.
