J Replace Nissan 240SX Rear Differential Axle Seal

Gear oil on the inside of a rear wheel or dripping from the differential housing where the axle stub enters is the sign of a failed differential axle seal. The J Replace Nissan 240SX rear differential axle seal fits the S13 and S14 240SX as well as the Z32 300ZX, and it is a must have whenever the axles or stub shafts come out of the differential.

When You Need This Seal

Any time you pull the axle stubs, whether for a limited slip differential install, a differential swap between chassis, or replacing a clicking CV axle, the seals should be replaced rather than reused. They are also the fix for the slow gear oil leak that leaves a film on the differential cover and lowers the fluid level over time. Each side uses its own seal, so order two to do the whole differential.

Install Tips

Clean the seal bore thoroughly, lightly oil the new seal lip, and drive the seal in square with a seal driver. Inspect the stub shaft sealing surface for grooves or rust and polish or replace the shaft if it is damaged, otherwise the new seal will leak too. Top off the differential with the correct gear oil afterward.
