  4.  
  5. Unbolt the driveshaft rear flange from the rear pinion flange.
  6.  
  7. Unbolt the driveshaft front flange from the rear transfer case flange and remove the driveshaft.
  8.  
  9. Position the driveshaft so that the paint marks made previously line up.
  10.  
  11. Install the flange bolts and tighten to 29-43 ft. lbs.
  12.  
  13. Lower the vehicle and road test it.
  14.  

For 4WD long bed Pick-Ups, see above for rear driveshaft removal and installation.

4WD Pick-Up and 4Runner-1984-88
  1. Raise the vehicle and support it with jackstands.
  2.  
  3. Matchmark all driveshaft flanges BEFORE removing any bolts.
  4.  
  5. Disconnect the driveshaft flange at the companion flange on the differential.
  6.  
  7. Remove the center bearing from the frame crossmember.
  8.  
  9. Disconnect the front flange at the companion flange on the rear of the transfer case and remove the driveshaft.
  10.  
  11. Separate the front portion of the shaft at the intermediate shaft flange.
  12.  
  13. Disconnect the rear of the driveshaft at the center bearing flange.
  14.  
  15. Using a hammer and chisel, loosen the staked portion of the center bearing nut and then remove the nut. Matchmark the flange to the intermediate shaft and then pull the bearing off the shaft.
  16.  

To install:
  1. Install the center bearing on the intermediate shaft and tighten the nut to 134 ft. lbs. (181 Nm), loosen the nut and then retighten it to 51 ft. lbs. (69 Nm). Stake the nut.
  2.  
  3. 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 and then tighten the bolts to 54 ft. lbs. (74 Nm).
  4.  
  5. Connect the rear flange to the differential flange and tighten the bolts to 54 ft. lbs. (74 Nm).
  6.  
  7. Connect the front flange to the transfer case flange and tighten the bolts to 54 ft. lbs. (74 Nm).
  8.  
  9. Mount the center bearing on the crossmember and tighten the mounting bolts to 27 ft. lbs. (36 Nm).
  10.  
  11. Lower the vehicle and give it a road test.
  12.  

Land Cruiser
  1. Raise the vehicle and support it with jackstands.
  2.  
  3. Matchmark all driveshaft flanges BEFORE removing the bolts.
  4.  
  5. Unfasten the bolts which secure the universal joint flange to the differential pinion flange.
  6.  
  7. Perform Step 2 for the U-joint-to-transfer case flange bolts.
  8.  
  9. Withdraw the driveshaft from beneath the vehicle.
  10.  

Lubricate the U-joints and sliding joints with multipurpose grease before installation.

  1. Position the driveshaft so that all paint marks line up and then tighten the flange bolts to 65 ft. lbs. (88 Nm).
  2.  
  3. Lower the vehicle and road test it.
  4.  

U-JOINT OVERHAUL



  1. Matchmark the yoke and the driveshaft.
  2.  
  3. Remove the snaprings from the bearings.
  4.  
  5. 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 25mm.
  6.  
  7. Place the tool in the vise and drive the yoke away from the tool until the bearing is removed.
  8.  
  9. Repeat Steps 3 and 4 for the other bearings.
  10.  
  11. Check for worn or damaged parts. Inspect the bearing journal surfaces for wear.
  12.  

To assemble:
  1. Install the bearing cups, seals, and O-rings in the spider.
  2.  
  3. Grease the spider and the bearings.
  4.  
  5. Position the spider in the yoke.
  6.  
  7. Start the bearings in the yoke and then press them into place, using a vise.
  8.  
  9. Repeat Step 4 for the other bearings.
  10.  
  11. If the axial play of the spider is greater than 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.
  12.  
  13. Check the U-joint assembly for smooth operation.
