  1. Jack the rear of the car up and support with jackstands.
  2.  
  3. Disconnect the inside trunnion from the carrier yoke.
  4.  
  5. On the outer end, bend down the locktabs and wire-brush the bolts.
  6.  
  7. Scratch a mark on the camber adjusting cam and the bracket to permit realignment.
  8.  
  9. Loosen the camber adjustment nut and turn the cam so that the eccentric end points inward. Doing this will push the trailing arm out and give more room for driveshaft removal.
  10.  
  11. Remove the driveshaft, outside end first.
  12.  

To install:
  1. Position the inside end of the driveshaft in the carrier yoke and assemble U-bolts or clamp and bolts. Torque the bolts to 14-18 ft. lbs.
  2.  

When removing and installing both axle driveshafts, be certain to position the carrier side yokes so that the trunnion seats are at 90° angles to each other.

  1. Install the outside end of the driveshaft into the spindle drive flange. Install the locks and bolts. Torque the bolts to 70-90 ft. lbs. and bend the locktabs up.
  2.  
  3. Realign the camber adjusting cam and bracket. Torque the nut to 15-22 ft. lbs.
  4.

Fig. Fig. 2: Disconnect the inboard driveshaft trunnion from the side gear yoke

  1. Raise the rear of the vehicle and support it safely with jackstands.
  2.  
  3. Disconnect the inboard driveshaft trunnion from the side gear yoke. Remove the plastic shield.
  4.  
  5. Disconnect the shaft flange from the spindle drive flange.
  6.  
  7. Mark the camber adjusting cam and the mounting bracket so that their relationship will be properly maintained during assembly.
  8.  
  9. Loosen the camber adjusting nut. Rotate the adjusting cam so that the high point of the cam faces inward, which pushes the control arm outward. This will provide additional working clearance.
  10.  
  11. Remove the driveshaft, outboard end first.
  12.  

To install:
  1. Place the inboard driveshaft trunnion into the side gear yokes. For vehicles using U-bolts with 1.06" dia. bearing caps, torque the bolts to 15 ft. lbs; for U-joints with 1.13" dia. bearing caps, torque the bolts to 25 ft. lbs.
  2.  
  3. Rotate the yokes so that the trunnion seats are phased 90° apart.
  4.  
  5. Attach the outboard end of the driveshaft in the same manner as step 7.
  6.  
  7. Install the plastic shield. Align the marks made during step 4 and torque the camber adjusting cam bolt to 130 ft. lbs.
  8.
