Differential Carrier: Testing and Inspection
Inspection Before Disassembly of Carrier
The differential case assembly and drive pinion should be inspected prior to removal from the carrier casting. These inspections can determine the cause
of the complaint and the resolution.
1. Wipe the lubricant from the internal working parts and visually inspect the parts for wear or damage.
2. Rotate the gears. Check any roughness which would indicate worn or damaged bearings or gears.
3. Check the ring gear teeth for signs of scoring, abnormal wear or nicks/chips.
4. Set up Dial Indicator with Bracketry TOOL-4201-C or equivalent and check ring gear backlash and ring gear backface runout.
