Jeep vehicles may come equipped with one of two different type front driveshafts. Type one has a conventional universal joint at the axle, but a double offset joint at the transfer case. Type two has a conventional universal joint at the axle and a double cardan joint at the transfer case.
Front driveshafts on 1984 vehicles use the type one universal joint only. Front driveshafts on 1985-98 vehicles use either type one or type two.
Removal & Installation
See Figures 1, 2, 3, 4 and 5
- Matchmark the shaft ends, axle and transfer case.
- Remove the U-joint strap bolts at the front axle yoke.
- If equipped with a double offset U-joint, remove the double offset joint flange nuts at the transfer case.
- If equipped with a double cardan U-joint, remove the double cardan joint flange nuts at the transfer case.
- Installation is the reverse of removal. Install new strap bolts and tighten strap bolts to 14 ft. lbs. (19 Nm).
FRONT DRIVESHAFT LENGTH ADJUSTMENT
See Figure 6
The length of the front driveshaft must be checked and adjusted if the shaft has been removed or replaced.
- Raise the vehicle on ramps.
- Measure from the rear edge of the groove at the transfer case end of the shaft, to the outer flange of the rubber boot on the double offset joint. The dimension should be 1 1 / 2 -1 3 / 4 in. (38.0-44.5mm).
- If not, loosen the slip joint locknut and slide the shaft in or out of the double offset joint to correct the length.
- Tighten the nut to 55 ft. lbs. (75 Nm).
