REMOVAL & INSTALLATION
See Figures 1 and 2
- Jack up the rear of the truck and support the rear axle housing with jackstands.
- Matchmark the two halves of the rear universal joint flange.
- Remove the bolts which hold the rear flange together.
- Remove the splined end of the driveshaft from the transmission.
Plug the end of the transmission with a rag or other device to prevent oil loss.
- Remove the driveshaft from under the truck.
- Apply multi-purpose grease to the splined end of the shaft.
- Insert the driveshaft sleeve into the transmission.
Be careful not to damage the extension housing grease seal.
- Align the mating marks on the rear flange and replace the bolts. Tighten to 54 ft. lbs. (74 Nm) on all vehicles except models with 3VZ-E engines and manual transmissions. Tighten to 56 ft. lbs. (76 Nm) on these models.
- Remove the jackstands and lower the vehicle.
- Jack up the rear of the truck and support the rear axle housing on jackstands.
- Before you begin to disassemble the driveshaft components, you must first paint accurate alignment marks on the mating flanges. Do this on the rear universal joint flange, the center flange, and on the transmission flange.
- Remove the bolts attaching the rear universal joint flange to the drive pinion flange.
- Drop the rear section of the shaft slightly and pull the unit out of the center bearing sleeve yoke.
- Remove the center bearing support from the crossmember.
- Separate the transmission output flange and remove the front half of the driveshaft together with the center bearing assembly.
- Connect the output flange of the transmission to the flange on the front half of the shaft.
- Install the center bearing support to the crossmember, but do not fully tighten the bolts.
- Install the rear section of the shaft making sure that all mating marks are aligned.
- Tighten all flange bolts to 22-36 ft. lbs. (30-49 Nm).
EXCEPT LAND CRUISER
See Figures 3, 4 and 5
- Raise and support the vehicle with jackstands.
- Matchmark all driveshaft flanges BEFORE removing any bolts.
- Disconnect the driveshaft flange at the companion flange on the differential.
- Remove the center bearing from the frame crossmember.
- Disconnect the front flange at the companion flange on the rear of the transfer case and remove the driveshaft.
- Separate the front portion of the shaft at the intermediate shaft flange.
- Disconnect the rear of the driveshaft at the center bearing flange.
- Using a hammer and chisel, loosen the staked portion of the center bearing nut, then remove the nut. Matchmark the flange to the intermediate shaft, then pull the bearing off the shaft.
- If equipped, install the center bearing on the intermediate shaft. Tighten the nut to 134 ft. lbs. (181 Nm), then loosen the nut, and retighten again to 51 ft. lbs. (69 Nm). Stake the nut.
- Connect the front portion of the driveshaft to the intermediate shaft and the rear portion to the center flange. Make sure the marks all line up, then tighten the bolts to 54 ft. lbs. (74 Nm).
- Connect the rear flange to the differential flange and tighten the bolts to 54 ft. lbs. (74 Nm).
- Connect the front flange to the transfer case flange and tighten the bolts to 54 ft. lbs. (74 Nm).
- Mount the center bearing on the crossmember and tighten the mounting bolts to 27 ft. lbs. (36 Nm).
- Lower the vehicle and road test.
See Figure 6
- Raise the vehicle and support it with jackstands.
- Matchmark all driveshaft flanges BEFORE removing the bolts.
- Unfasten the bolts which secure the universal joint flange to the differential pinion flange.
- Matchmark all of the flanges for the joint-to-transfer case flange bolts.
- Withdraw the driveshaft from beneath the vehicle.
Lubricate the U-joints and sliding joints with multi-purpose grease before installation.
- Position the driveshaft so that all marks line up, then tighten the flange bolts to 65 ft. lbs. (88 Nm).
- Lower the vehicle and road test it.
See Figures 7 through 11
- Raise and support the vehicle.
- Remove the driveshaft.
- Matchmark the yoke and the driveshaft.
- Remove the snaprings from the bearings. There are two types of snaprings: 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, then press them into place, using a vise.
- Repeat Step 5 for the other bearings.
- If the axle play of the spider is greater than 0.0020 in. (0.05mm), select snaprings which will provide the correct play. Be sure that the snaprings are the same size on both sides or driveshaft noise and vibration will result.
- Check the U-joint assembly for smooth operation.
