REMOVAL & INSTALLATION
See Figures 1, 2 and 3
- Raise the rear of the car with jacks and support the rear axle housing with jackstands.
Be sure to matchmark the yoke flange to the mounting flange on the drive pinion
- Unfasten the bolts which attach the driveshaft universal joint yoke flange to the mounting flange on the differential drive pinion.
On models equipped with three universal joints, perform the following:
- Withdraw the driveshaft subassembly from the U-joint sleeve yoke.
- Unfasten the center support bearing from its bracket.
- Remove the driveshaft end from the transmission.
- Install an old U-joint yoke in the transmission or, if nothing is available, use a plastic bag secured with a rubber band over the hole to keep the transmission oil from running all over the place.
- Withdraw the driveshaft from beneath the vehicle.
- Installation is performed in the following order. Apply multipurpose grease on the section of the U-joint sleeve which is to be inserted into the transmission.
- Insert the driveshaft sleeve into the transmission.
Be careful not to damage any of the seals
For models equipped with three U-joints and center bearings, perform the following:
- Adjust the center bearing clearance with no load placed on the driveline components; the top of the rubber center cushion should be 0.04 in. (1mm) behind the center of the elongated bolt hole.
- Install the center bearing assembly.Use the same number of washers on the center bearing bracket as were removed
- Secure the U-joint flange to the differential flange with the mounting bolts.
Be sure that the bolts are of the same type as those removed and that they are tightened securely
- Remove the jackstands and lower the vehicle.
See Figures 4 and 5
The U-joints on some late model vehicles are non-serviceable, the entire driveshaft must be replaced in the event of U-joint problems
- Matchmark the yoke and the driveshaft.
- Remove the lockrings from the bearings.
- Position the yoke on vise jaws. Using a bearing remover and a hammer, gently tap the remover until the bearing is driven out of the yoke about 1 / 2 in. (13mm).
- Place the tool in the vise and drive the yoke away from the tool until the bearing is removed.
- Repeat Steps 3 and 4 for the other bearings.
- Check for worn or damaged parts. Inspect the bearing journal surfaces for wear.
- Install the bearing cups, seals, and O-rings in the spider.
- Grease the spider and the bearings.
- Position the spider in the yoke.
- Start the bearings in the yoke and then press them into place, using a vise.
- If the axial play of the spider is greater than 0.002 in. (0.05mm) select lockrings which will provide the correct play. Be sure that the lockrings are the same size on both sides or driveshaft noise will result. If the U-joint is in doubt replace the joint or entire driveshaft, as necessary.
- Check the U-joint assembly for smooth operation.
