Rear Differential
hello, quick question....hoping someone has experience with rear diff work...i posted before, i had a grinding screaming sound coming from the rear differential...i took the diff cover off and removed pin and c clamps then removed axels and then used a special tool to shove down axel shaft to loosen these collars that press on each side of the diff bearings...my question is how tight do i make these collars with this tool when i reinstall the differential? it was a bearing on the differential making all the noise by the way so i removed both and the wheel bearings too why its apart....sorry for the way im describing this, its hard for me to describe it...thanks for any help you guys can give me...

SIDE GEAR CLEARANCE
When measuring side gear clearance, check each
gear independently. If it necessary to replace a side
gear, replace both gears as a matched set.
(1) Install the axle shafts and C-locks and pinion
shaft.
(2) Measure each side gear clearance. Insert a
matched pair of feeler gauge blades between the geargear independently. If it necessary to replace a side
gear, replace both gears as a matched set.
(1) Install the axle shafts and C-locks and pinion
shaft.
(2) Measure each side gear clearance. Insert a
and differential housing on opposite sides of the hub
(3) If side gear clearances is no more than 0.005
inch. Determine if the axle shaft is contacting the
pinion shaft.
pinion shaft.
Do not remove the feeler gauges,
inspect the axle shaft with the feeler gauge
inserted behind the side gear. If the end of the
axle shaft is not contacting the pinion shaft, the side
gear clearance is acceptable.
(4) If clearance is more than 0.005 inch (axle shaft
not contacting pinion shaft), record the side gear
inspect the axle shaft with the feeler gauge
inserted behind the side gear. If the end of the
axle shaft is not contacting the pinion shaft, the side
gear clearance is acceptable.
(4) If clearance is more than 0.005 inch (axle shaft
not contacting pinion shaft), record the side gear
clearance. Remove the thrust washer and measure
its thickness with a micrometer. Add the washer
thickness to the recorded side gear clearance. The
sum of gear clearance and washer thickness will
determine required thickness of replacement thrust
washer (Fig. 16). In some cases, the end of the axlethickness to the recorded side gear clearance. The
sum of gear clearance and washer thickness will
determine required thickness of replacement thrust
shaft will move and contact the pinion shaft when
the feeler gauge is inserted. The C-lock is preventing
the side gear from sliding on the axle shaft.
(5) If there is no side gear clearance, remove the
C-lock from the axle shaft. Use a micrometer to measure
the thrust washer thickness. Record the thickness
and re-install the thrust washer. Assemble the
differential case without the C-lock installed and remeasure
the side gear clearance.
(6) Compare both clearance measurements. If the
difference is less than 0.012 inch (0.305 mm), add
clearance recorded when the C-lock was installed to
thrust washer thickness measured. The sum will
determine the required thickness of the replacement
thrust washer.
(7) If clearance is 0.012 inch (0.305 mm) or
greater, both side gears must be replaced (matched
set) and the clearance measurements repeated.
(8) If clearance (above) continues to be 0.012 inch
(0.305 mm) or greater, the case must be replaced.the feeler gauge is inserted. The C-lock is preventing
the side gear from sliding on the axle shaft.
(5) If there is no side gear clearance, remove the
C-lock from the axle shaft. Use a micrometer to measure
the thrust washer thickness. Record the thickness
and re-install the thrust washer. Assemble the
differential case without the C-lock installed and remeasure
the side gear clearance.

difference is less than 0.012 inch (0.305 mm), add
clearance recorded when the C-lock was installed to
thrust washer thickness measured. The sum will
determine the required thickness of the replacement
thrust washer.
(7) If clearance is 0.012 inch (0.305 mm) or
greater, both side gears must be replaced (matched
set) and the clearance measurements repeated.
(8) If clearance (above) continues to be 0.012 inch
