Spicer Differential Pinion Seal P/N:44895
DANA SPICER 10039487 rear differential pinion seal for the 2018-2023 Jeep Wrangler and other vehicles seals the differential where the pinion shaft passes through the housing. The seal body stays stationary while its lip rides on the rotating shaft.
Differential fluid seeping where the pinion shaft leaves the differential, or an oily film on the nearby housing, can mean the pinion seal is worn. Those signs alone do not prove the seal is at fault, because a leaking cover gasket can leave oil in the same area.
This seal fits the 2018-2023 Jeep Wrangler, the 2021-2022 Ford Bronco and the 2020-2022 Jeep Gladiator. It is built to the OE standards Dana sets, and it is tested and validated to rigorous OE specifications.
