See Figures 1 through 6
Two types of driveshafts are used, designated types 1 and 2, depending on the type of bearing cap retaining ring. See the illustration.
REMOVAL & INSTALLATION
- Mark the rear universal joint yoke and bearing retainers so that you can reinstall them in their original positions.
- Remove the U-bolts, being careful not to lose the round bearing retainer caps, which are filled with little needle bearings. Don't make any attempt to remove the large nut holding the yoke to the front of the rear axle assembly.
- Slide the driveshaft back and remove it.
- On installation, slide the front yoke on the transmission output shaft splines far enough to align the rear universal joint.
- Align the marks you made in Step 1.
- Install the rear U-bolts and tighten them evenly to 15 ft. lbs. A torque wrench isn't essential here, but remember that 15 ft. lbs. isn't very much. You can crush the bearings and retainer caps if you get carried away.
See Figure 7
Both driveshafts are secured at the transfer case end and the axle yoke end by straps. The straps are retained by Torx head bolts.
- Shift into Neutral. Raise and support the car.
- Matchmark the driveshaft(s) at the transfer case and axle yoke for alignment reference.
- Remove the retaining straps with a Torx bit tool of the proper size. Remove the driveshaft(s).
- To install, align the matchmarks made during removal to assure proper balance. Seat the universal joints in the yokes and install the straps, tightening to 17 ft. lbs.
See Figures 8 through 22
The four end bearings or roller retainers are held in the yoke ends by snaprings on the front U-joint. The rear U-joint has 4 retainers held by U-bolts.
- The snaprings can be pried out with a screwdriver.
- Place the assembly in a vise with a 9 / 16 in. socket against the bearing retainer on one side and a 1 1 / 8 in. socket against the yoke on the other side.
- Tighten the vise slowly; the bearing retainer will be forced out into the big socket.
- Clamp the protruding bearing retainer gently in the vise and remove it. Watch our for the little needle bearings inside.
- Remove the other bearings retainers in the same way.
- Wash all the parts in a safe solvent and check carefully for wear. These parts aren't very expensive and aren't serviced often, so replace any doubtful parts. The 4-armed part is called a cross or a spider.
- Pack enough high quality grease into each bearing retainer so that you can install the needle bearings without them falling out.
- Install the cross into the yoke and put the end bearing retainer in place.
- Place the yoke in a vise and press the bearing retainer, using a 9 / 16 in. socket, past the outside of the yoke.
- Install the snaprings, making sure that they are securely seated.
