10-8. DIFFERENTIAL AND DIFFERENTIAL CARRIER REPAIR (Contd)
NOTE
Coat bearings and races with clean gear oil before installation.
34.
Using bearing cup replacer, install race (2) in bearing cap (1). Thick edge of race (2) must be toward
small end (6) of bearing cap (1).
Install bearings (3) and (4) and race (5) in bearing cap (1). Use installer/remover tool to seat race (5)

in bearing cap ( 1). Wide edge of race (5) must face away from face of cap.
36.
Starting with same thickness of shims (9) as removed, place shim (9) pack over shaft (8) and on
differential carrier housing (7). Carefully aline holes in shims (9) to holes in earner housing (7).
Place bearing cap (1) over shaft (8) and press bearing cap (1) into position on shaft (8) to differential

earner housing (7).
Install retaining plate (10) on shaft (8) with three screws (12). Tighten screws (12) 42-54 lb-ft

and install new safety wire (11) in screws (12).
(57-73
Install new shims (13) and bearing cover (14) on differential earner housing (7) with six new

lockwashers (15) and screws (16). Select shims (13) to be same thickness as removed. Tighten
screws (16) 60-100 lb-ft (81-136
40.
To measure helical pinion gear (17) bearing preload, wrap twine around helical pinion gear (17) and
attach to bearing preload tester. Observe pointer and pull on bearing preload tester until helical
pinion gear (17) starts to rotate. Record value.
NOTE
If preload is not within given limits, perform steps 41 through 45.
If preload is within given limits, go to step 46.
41.
Remove six screws (16), lockwashers (15), bearing cover (14), and shims (13) from differential
carrier housing (7). Remove shims (13) carefully to avoid creasing or damaging shims.
42.
If preload scale (or torque) reading of steps 40, 41, and 42 exceed limits, add shims (13).
43.
If preload scale (or torque) reading of steps 40, 41, and 42 is less than lower limit, remove
shims (13).
Install shims (13) and bearing cover (14) on differential carrier housing (7) with six screws (16) and

new lockwashers (15). Carefully aline shims (13) with holes in differential carrier housing (7).
Tighten screws (16) 60-100 lb-ft (81-136
