Overview
The Crown Automotive 3893982 is an inner pinion oil slinger for the Dana 30, mounted at the front position. It fits the 1993-1998 Jeep Cherokee (XJ), the CJ5, the CJ7, the 1993-1998 Grand Cherokee (ZJ), the J10 and J20, the Scrambler and the 1987-1995 Wrangler (YJ).
An inner pinion slinger sits behind the pinion seal and flings oil away from it, protecting the seal from excess leakage. It is one of the small items in a front differential rebuild.
Compare the new slinger with the old one before installing, checking size and fit at the pinion.
The Dana 30 front differential is found in many of the Jeeps on this list. The slinger sits inside the housing at the pinion, so it is usually replaced when the pinion seal is.
A differential rebuild is a good time to replace this small part, since the pinion seal is already out.

Pinion seal and slinger service
The pinion seal sits at the front of the differential where the driveshaft yoke turns the pinion. The inner slinger sits just inside it, catching oil that works past the bearings and throwing it away from the seal lip. A worn or missing slinger lets more oil reach the seal, which can speed up leakage around the yoke.
When rebuilding, the slinger is usually replaced along with the pinion seal because both are removed during the same work. Clean the pinion shaft, check it for grooves or rust, and make sure the new slinger is seated flat before the yoke goes back on. Recheck the fluid level once the vehicle has been driven a short distance.
- Check the pinion shaft for grooves or rust
- Install the slinger in the same orientation as the old one
- Replace the pinion seal and slinger together
- Look for oil around the yoke after the first drives
