Solution

1. Preparation

Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Gather necessary tools and parts.

2. Fluid Check and Replacement

Sub-steps:
1. Remove the differential fill plug using a socket wrench.
2. Insert a dipstick or similar tool to check the fluid level; it should be just below the fill hole.
3. If fluid is low, drain the old fluid by removing the drain plug and allow it to fully drain.
4. Inspect the old fluid for metal shavings or burnt smell.
5. Replace with new differential fluid (refer to owner’s manual for specifications).
Tools Required:
- Socket set
- Drain pan
- Torque wrench

3. Differential Inspection

Sub-steps:
1. With the vehicle lifted, check for play in the differential by moving the driveshaft side-to-side.
2. Remove the differential cover if necessary to inspect gears and bearings.
3. Look for signs of wear on the gears or bearings, such as pitting or scoring.
4. Replace any damaged components, such as bearings or seals.
Tools Required:
- Socket set
- Screwdrivers
- Gasket scraper

4. Reassembly

Sub-steps:
1. Clean the differential cover and apply a new gasket or sealant as needed.
2. Reinstall the differential cover and torque bolts to manufacturer specifications.
3. Refill the differential with the correct type and amount of fluid.
4. Reinstall the fill plug and torque to specification.
