    Important: Observe the position of all the driveline components. Accurately mark the relationship of the components before removal. These components include the propeller shafts, the drive axles, the pinion flanges, and the output shafts. Reassemble all components in the exact relationship to each other as they were before removal. Follow the specifications, the torque values, and any measurements obtained prior to disassembly.

  1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the steering gear crossmember. Refer to Rear Steering Gear Crossmember Replacement in Frame and Underbody.
  3. Reference mark the relationship of the propeller shaft to the front axle pinion yoke.
  4. Remove the yoke retainer bolts and yoke retainers from the front axle pinion yoke.
  5. Notice: When removing the propeller shaft, do not attempt to remove the shaft by pounding on the yoke ears or using a tool between the yoke and the universal joint. If the propeller shaft is removed by using such means, the injection joints may fracture and lead to premature failure of the joint.

  6. Disconnect the propeller shaft from the front axle pinon yoke.
  7. Wrap the bearing caps with tape in order to prevent the loss of bearing rollers.
