Inspect carrier housing (12), two bearing caps (6), and adjusting nuts (10). Replace carrier
housing (12) if bearing caps (6) are cracked or distorted. Replace carrier housing (12) or adjusting
nuts (10) if cracked, cross-threaded, or stripped.
Inspect two bearings (1) and bearing seats (11) and (13) for chips or distortion. Replace bearings (1)
or bearing seats (11) and (13) if chipped or distorted.
Measure inside diameter of inner race on two bearings (1). Refer to table 10-3, Wear Limits, for
measurements. Replace bearings (1) if not within wear limits.
Inspect two case halves (2) for chips, cracks, or distortion. Replace differential assembly (14) if case
halves are chipped, cracked, or distorted.
Measure outside diameter of case halves
(2)
at point where bearing (1) inner race fits. Refer to table
10-3, Wear Limits, for measurements. Replace differential assembly (14) if case halves (2) are not
within wear limits.
Inspect helical drive gear (5) teeth for chips, breaks, cracks, burrs, or uneven wear. Replace helical
drive gear (5) if teeth are chipped, broken, cracked, burred, or worn unevenly.
Inspect two thrust washers (3), side gears (4), four thrust washers (9), pinion gears (8), and
spider (7) for chips, breaks, cracks, burrs, or uneven wear. Replace two thrust washers (3), side
gears (4), four thrust washers (9), pinion gears (8), and spider (7) if any are chipped, broken,
cracked, burred, or worn unevenly.
Measure inside diameter of four pinion gears (8). Refer to table 10-3, Wear Limits, for measure-
ments. Replace two thrust washers (3), side gears (4), four thrust washers (9), pinion gears (8), and
spider (7) if any pinion gear (8) is not within wear limits.
Measure outside diameter of each arm of spider (7). Refer to table 10-3, Wear Limits, for
measurements. Replace two thrust washers (3), side gears (4), four thrust washers (9), pinion
gears (8), and spider (7) if any arm of spider (7) is not within wear limits.
