REMOVAL & INSTALLATION
- Jack up the front of the vehicle and support with jackstands.
- Place matchmarks on the flanges. Remove the nuts and bolts.
- Remove the front driveshaft dust cover. Some types are equipped with two bolts, while others use four bolts.
- Remove the driveshaft dust cover sub-assembly. Note that the three bolts are different sizes. Note the original location of each for proper re-installation.
The driveshaft dust cover is located around the outer portion of the U-joint. On some models you may have an upper and lower dust cover.
- Suspend the front side of the driveshaft securely from the chassis.
- Remove the nuts and bolts.
- Remove the front driveshaft.
- Align the matchmarks on the rear flanges, then connect the flanges with the nuts and/or bolts. Tighten to 54 ft. lbs. (74 Nm).
- Install the front driveshaft dust cover sub-assembly. Tighten bolt A to 27 ft. lbs. (36 Nm) and bolt B to 17 ft. lbs. (23 Nm).
- Align the matchmarks on the front flanges, then connect the flanges with the bolts and nuts. Tighten to 54 ft. lbs. (74 Nm).
- Install the front driveshaft dust cover. Tighten the bolts to 13 ft. lbs. (17 Nm) and the nuts to 10 ft. lbs. (13 Nm).
- Attach the rear driveshaft flange to the companion flange on the transfer case. Align the matchmarks on the flanges, and then connect the flanges with the bolts and nuts. Tighten to 5456 ft. lbs. (7476 Nm).
- Lower the vehicle and road test it.
- Raise and support the vehicle.
- Remove the driveshaft.
- Matchmark the yoke and the driveshaft.
- Remove the snap rings from the bearings. There are two types of snap rings: Toyota and Dana.
- 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 in. (25mm).
- Place the tool in the vise and drive the yoke away from the tool until the bearing is removed.
- Repeat Steps 4 and 5 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.
- Apply multi-purpose grease to a new spider and bearings. Be careful not to apply too much grease.
- Position the spider into the yoke.
- Start the bearings in the yoke, and then press them into place, using a vise. Repeat for the other bearings.
- If the axial play of the spider is greater than 0.0020 in. (0.05mm), select snap rings which will provide the correct play. Be sure that the snap rings are the same size on both sides or driveshaft noise and vibration will result.
- Check the U-joint assembly for smooth operation.
When replacing the driveshaft U-joints on a 4WD vehicle, be sure that the grease fitting is accessible after the joint is assembled.
