Overview
The Rugged Ridge transfer case output shaft oil seal 18676.75 is a service seal for the Rugged Ridge Mega Short slip yoke eliminator (SYE) kit, part number 18676.72. A slip yoke eliminator replaces the slip yoke at the transfer case output so the driveshaft connects directly. It fits 1997–2006 Jeep Wrangler (TJ) and 1987–1995 Jeep Wrangler (YJ) models.

Slip yoke eliminator basics
A slip yoke eliminator removes the slip yoke from the transfer case output, so the driveshaft is held in place by a fixed yoke. This setup is often chosen to reduce driveline vibration and simplify driveshaft length on lifted Wranglers, though the output still needs a seal that suits the kit.
Because the transfer case output is opened during the conversion, the seal, bearing surfaces and output shaft should be inspected before assembly. Using a service seal made for the kit helps keep lubricant inside the case after the yoke is removed. Check driveshaft angles after the change, since the new setup can alter how the driveline sits.
- Measure driveshaft length after conversion
- Check driveshaft angles under load
- Inspect the output shaft before assembly
- Recheck fluid level after the first drives
