Disassembly & Assembly Of Subassemblies: Differential: Disassembly

Fig 1: Exploded View Of Differential

1. Inspect the differential.
   • Inspect for damaged or worn gears.
   • Inspect for cracked or damaged gear case.
2. Use Dial Indicator/Magnetic Base to measure the backlash of the side gears and pinions. If backlash is not within specification, replace the differential as an assembly.
   1. Install the LH and RH halfshafts.
   2. Support the halfshafts on V-blocks.
   3. Measure the backlash of the side gears and pinions.
