Jeep Wrangler/YJ 1987-1995 Repair Guide

Front Driveshaft and U-Joints

Print

The front driveshaft has a single cardan universal joint at each end. A slip yoke is used to attach the shaft to the front axle yoke.

The rear driveshaft is one-piece with a single cardan universal joint at each end. A slip yoke is used to attach the shaft to the transfer case output yoke.

Some slip joints are marked with arrows at the spline and sleeve yoke. When installing, align the arrows. If the slip joint is not marked with arrows, align the yokes at the front and rear of the shaft in the same horizontal plane. Scribe alignment marks as necessary for correct installation in order to avoid vibration in the drive train.
