1. Use a J 26900-2 to measure the outer diameter of the input shaft journal surfaces.
Important: If any of the journal surfaces are under specifications, replace the input shaft.
(1) 24.87 mm (0.9791 inch)
(2) 28.97 mm (1.1405 inch)
(3) 30.97 mm (1.2193 inch)
(4) 24.97 mm (0.9831 inch)
2. Use a J 8001 and a J 26900-13 to inspect the input shaft runout. If the runout exceeds 0.05 mm (0.0020 inch), replace the input shaft.
3. Use a J 26900-2 to measure the outer diameter of the output shaft journal surfaces (1,2,3,4) .
Important: If any of the journal surfaces are under specifications, replace the output shaft.
3.1. (1) 32.97 mm (1.2980 inch)
3.2. (2) 37.97 mm (1.4949 inch)
3.3. (3) 31.97 mm (1.2587 inch)
4. Use a J 8001 and a J 26900-13 to inspect the output shaft runout. If the runout exceeds 0.05 mm (0.0020 inch), replace the output shaft.
5. Inspect the synchronizer rings by turning and pushing on them in order to test the braking action.
6. Inspect the synchronizer ring clearance by measuring between the back of the synchronizer ring and the gear spline end. If clearance is less than 0.6 mm (0.024 inch), replace the synchronizer ring.
7. Use a feeler gage to measure the clearance between the hub sleeve and the shift fork. If the clearance exceeds 1.0 mm (0.0039 inch), replace the shift fork or replace the hub sleeve.
8. Remove the input shaft front seal.
9. Remove the bearing lock plate.
10. Inspect the input shaft front bearing. If you must replace the bearing, use a J 23907 and a J 29369-1.
11. Use a J 8092 and a J 35656 to install the bearing.
12. Inspect the output shaft front bearing. If you must replace the bearing, use a J 23907 and a J 29369-2.
13. Install the bearing use a J 8092 and a J 35657.
14. Use a J 33183 to install the input shaft front seal. Lightly coat the seal lip with GM #1051344.
15. Install the bearing lock plate.
^ Tighten the bearing lock bolts to 11 Nm (97 inch lbs.).
16. Inspect the RH differential oil seal and inspect the LH differential oil seal. If replacement is necessary, remove the seal with a screwdriver.
17. Use a J 35553 to install a new seal flush with the case surface. Lightly coat the seal lip with GM #1051344.
18. Inspect the RH differential bearing cap and the LH differential bearing cap. If replacement is necessary, use a J 35399 to remove the bearing caps.
19. Use a J 35552 to install the bearing caps.
20. Inspect the control shaft cover seal. If replacement is necessary use the following procedure:
20.1. Remove the old seal with a screwdriver.
20.2. Tap in a new seal.
20.3. Coat the lip of the seal with GM #1051344.
21. Inspect the speedometer seal. If replacement is necessary remove the old seal.
22. Coat the new seal with GM #1051344.
23. Install the seal to a depth of 25 mm (0.98 inch).
24. Inspect the reverse restrict pin. If replacement is necessary, perform the following procedure:
24.1. Remove the reverse restrict holder.
24.2. Using a pin punch and a hammer, driver out the slotted spring pin.
24.3. Replace the reverse restrict pin.
24.4. Driver in the slotted pin.
