REMOVAL & INSTALLATION
The following procedure applies only to 4 x 4 vehicles.
- Raise and safely support the vehicle securely on jackstands.
- If equipped, remove 3 front driveshaft shield retaining nuts and remove the driveshaft shield.
- Matchmark the driveshaft yoke and axle pinion flange.
- Matchmark the driveshaft yoke and transfer case flange.
- Remove the bolts retaining the yoke to the axle flange.
- Separate the yoke from the flange. It may be necessary to pry it free with a small prybar.
- Remove the bolts and disconnect the driveshaft from the transfer case. It may be necessary to pry it free with a small prybar.
- Place the driveshaft to the transfer case flange and axle pinion flange noting the index marks made during removal. Tighten the bolts to 87 ft. lbs. (119 Nm).
- If equipped, install the front driveshaft shield and 3 retaining nuts.
- Road test the vehicle and check for proper operation.
Single Cardan Universal
- Remove the driveshaft from the vehicle and place it in a vise, being careful not to damage it.
- Remove the snaprings which retain the bearings in the flange and in the driveshaft.
- Place U-Joint Tool T74P-4635-C or an equivalent joint press, onto the driveshaft.
- Slowly tighten the tool to press the spider towards one side. When it will not move any further, remove the tool and pull the bearing cup out of the bore with pliers.
- Remove the other bearing cup in the same manner and remove the spider assembly from the driveshaft. Discard the spider assemblies.
- Clean the yoke bores with light sand paper being careful not to change the dimension of the bores.
- Remove the bearing cups from the new universal joint. Make sure all the needle bearings are still in place and held against the sides of the bearing cups with grease.
- Start a new bearing cup into place with the press. When the cup is firmly held in place but still below the inner edge of the bore, install the spider. Be careful not to push a needle bearing out of place.
- Fit the bearing cup into the other side of the bore and begin pressing it into place. Press the cup a little at a time and keep checking to make sure the spider turns freely in both cups. When both cups are pressed fully against the spider, install the snaprings.
If the bearing cups will not press in far enough to install a snapring or if the spider stops moving freely, a needle bearing has fallen out of place in one of the bearing cups. Stop pressing and disassemble the universal joint to re-position the bearings. If assembly is forced, the needle bearings and cups will be destroyed.
- Install the remaining joint in the same manner.
- Install the driveshaft and grease the new universal joints.
