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. 25. 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. 26. Measure inside diameter of inner race on two bearings (1). Refer to table 3, Wear Limits, for measurements. Replace bearings (1) if not within wear limits. 27. Inspect two case halves (2) for chips, cracks, or distortion. Replace differential assembly (14) if case halves are chipped, cracked, or distorted. 28. Measure outside diameter of case halves (2) at point where bearing (1) inner race fits. Refer to table 3, Wear Limits, for measurements. Replace differential assembly (14) if case halves (2) are not within wear limits. 29. 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. 30. 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.

Measure inside diameter of four pinion gears (8). Refer to table 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 pinion gear (8) is not within wear limits. 32. Measure outside diameter of each arm of spider (7). Refer to table 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. Table 3. Wear Limits. ITEM NO.
