Right Axle Tube Assembly: Reassembly
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 1990 GMC Pickup, 1990 GMC Cab & Chassis, 1990 Chevrolet Pickup, 1990 Chevrolet Cab & Chassis, and 1989 GMC Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Clean parts in clean solvent. Clean gasket surfaces on axle tube and carrier housing. Lubricate new bearing using axle grease. Using appropriate bearing driver, install bearing into end of axle tube. Coat lip of new seal with grease. Using appropriate installer, install seal.
- Install deflector and insert axle shaft into axle tube. Install thrust washer, ensuring notch on tube aligns with tabs and notch on washer. See Fig 1. Use axle grease to hold thrust washer in place.
- On K10/20 Series, drive connector gear onto end of axle using a plastic hammer. Install snap ring. On K30 Series, install washer and snap ring. Ensure snap ring seats properly in groove. An output shaft shim of proper thickness must be selected if any of the following parts have been changed. If not, go to step 6).
- Differential Case
- Carrier Connector (K10/20 Series)
- Output Shaft
- Ring and Pinion
- Inner Shaft
- Axle Tube
- Carrier Case
- Bearings
- If any of the listed parts have been changed, use grease to hold ORIGINAL shim in place. Assemble axle tube and inner shaft assembly to carrier. Use no sealer at this time. Torque bolts to 30 ft. lbs. (40 N.m).
- Install dial indicator onto axle tube with dial indicator shaft at right angle to axle output shaft flange. Check axle shaft end play by pushing and pulling in and out on axle shaft. Maximum end play is .001-.020" (.03-.51 mm). If end play is incorrect, select shim as necessary to bring end play within specification. Remove axle tube from carrier.
- Clean axle tube and carrier case sealing surfaces. Place correct shim onto output shaft. Hold shim in place with axle grease. Slip damper spring onto shift shaft. Slide shift fork onto shift shaft, ensuring damper spring fits into indentation in shift fork.
- Install clip, ensuring clip seats properly in shift shaft indentation. Install tension spring on shift shaft. Attach shift fork assembly to carrier case. Apply a bead of Loctite (518) or appropriate sealant to axle tube sealing surface. Assemble axle tube to carrier case. Install axle tube-to-carrier bolts and torque to specification.
- Inspect shift mechanism operation by inserting a drift into shift actuator hole on axle tube. Rotate axle shaft flange while moving the shift mechanism back and forth with drift. Shift mechanism should work smoothly without binding.
- Apply Loctite (518) or appropriate sealant to threads of solenoid and install solenoid onto axle tube. Repeat procedure with switch assembly.
