Solution

1. Preparation

Gather Tools:
- Jack and jack stands or hydraulic lift
- Socket set
- Torque wrench
- Differential fluid (as specified in the owner’s manual)
Safety Warnings:
- Ensure the vehicle is securely lifted and supported.
- Wear safety glasses and gloves.

2. Fluid Change

Drain Old Fluid:
1. Place a catch pan under the differential.
2. Remove the drain plug with a socket or wrench.
3. Allow the old fluid to completely drain out.
Inspect Drain Plug:
1. Clean the drain plug and inspect for any metal shavings.
2. Replace if excessively worn.

3. Replace Differential Fluid

Refill with New Fluid:
1. Replace and tighten the drain plug to manufacturer specifications (consult owner’s manual for torque values).
2. Remove the fill plug and use a fluid pump to refill the differential with the new fluid until it reaches the fill hole level.
3. Reinstall the fill plug and tighten to manufacturer specifications.

4. Test Drive

Conduct a Test Drive:
1. Drive the vehicle to check for any changes in noise after the fluid change.
2. Listen for any residual noises during acceleration, deceleration, and turning.
