U-JOINT OVERHAUL



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

  1. Matchmark the yoke and the driveshaft.
  2.  
  3. Remove the lockrings 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 1 / 2 in. (13mm).
  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. 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.

  11. Check the U-joint assembly for smooth operation.
