Inspection
Fig. 4 Measuring Pinion To Side Gear Backlash
Thoroughly clean all disassembled parts, and examine them to see that they are worn, damaged or otherwise faulty, and how they are affected. Repair
or replace all faulty parts, whichever is necessary.
1.
Check gear teeth for scoring, cracking or chipping, and make sure that tooth contact pattern indicates correct meshing depth. If any fault is evident,
replace parts as required.
Drive pinion and drive gear are supplied as a set; therefore, should either part be damaged, replace as a set.
2.
Check pinion gear shaft, and pinion gear for scores and signs of wear, and replace as required. Follow the same procedure for side gear and their
seats on differential case.
3.
Inspect all bearing races and rollers for scoring, chipping or evidence of excessive wear.
4.
Inspect thrust washer faces. Small faults can be corrected with sandpaper. Inspect pinion mate-to-side gear backlash,
Fig. 4. If clearance between
side gear and thrust washer exceeds .0039-.0079 inch®MDBO¯ ®MDNM¯ (less than .0059 inch on models), replace thrust washers.
5.
Inspect carrier and differential case for cracks or distortion. If either condition is evident, replace faulty parts.
