WARNING
Use a brass or plastic mallet for assembly and
disassembly procedures. Do not hit steel parts
with a steel hammer. Serious personal injury
and damage to components can result.
CAUTION
IF BEARING CAPS ARE NOT INSTALLED
CORRECTLY IN THE ORIGINAL DIFFEREN-
TIAL CASE LOCATIONS, THE BORES AND
THREADS IN THE CAPS WILL NOT MATCH
THE DIFFERENTIAL CASE. FORCING THE
BEARING CAPS INTO THE INCORRECT PO-
SITION WILL RESULT IN DAMAGE TO THE
DIFFERENTIAL CASE.
9. Use a light leather plastic or rubber mallet to
seat each bearing cap. The caps must fit easily
against the bearings, adjusting rings and
differential case. Do not force the bearing
caps into position.
• If the bearing caps do not correctly fit in the
position, check the alignment of the match
marks between the caps and differential
case. Remove the caps and repeat Step 7
through Step 9.
10. Install the capscrews and washers that
secure the bearing caps to the differential
case . Hand-tighten the capscrews 4 our to
6 turns. Then tighten the capscrews to the
correct torque value. See the Section 8. Do
not install the capscrews, cotter pins or roll
pins, if equipped, that secure the bearing adjusting
rings in position. Continue by adjusting
the preload of the differential bearings, adjust
the backlash of the hypoid gear and inspect
the tooth contact patterns.
