Overview
The Crown Automotive J0998092 is a front pinion seal for Dana 30 and Dana 44 front axles. It fits the 1984 to 1990 Jeep Cherokee XJ, 1976 to 1983 CJ5, 1976 to 1986 CJ7, 1986 to 1992 Comanche, 1974 to 1986 J10, 1981 to 1985 Scrambler and 1987 to 1990 Wrangler YJ.
The front pinion seal keeps gear oil in the differential where the pinion shaft passes through the front housing. It is for the front position only.
Pinion seal wear and checks
A pinion seal keeps gear oil in the front differential where the pinion shaft passes through the housing. Its lip hardens and wears over time, and a leaking seal can lower the oil level and let dirt in past the yoke. Leaks often show as oil on the front of the housing or on the inside of the tire.
Before replacing a pinion seal, check the yoke for grooves, since a rough yoke can cut into a new seal lip. Check the pinion bearing preload and the companion flange as well, because a loose flange can cause leaks. Use a seal driver so the lip is not damaged during installation.
- Inspect the yoke for grooves
- Check pinion bearing preload
- Look at the companion flange nut
- Clean the housing before fitting the seal
