- Torque wrench
- Fluid catch pan
- Transmission fluid (as specified in the owner's manual)

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or inspection plug based on the vehicle's service manual.
2. Remove the dipstick or plug and check the fluid level with the engine running (if applicable).
3. If fluid is low, add the recommended transmission fluid until the proper level is reached.
4. If fluid is contaminated, drain the old fluid by removing the drain plug and allow it to completely empty into a fluid catch pan.
5. Replace the drain plug and refill with new transmission fluid, ensuring it meets the manufacturer's specifications.

3. Inspect and Replace Damaged Components

Sub-steps:
1. Inspect the driveshaft and CV joints for damage or excessive play; replace any worn or damaged parts.
2. Check the differential for signs of wear or damage; replace the differential fluid if necessary.
3. Reassemble any components that were removed for inspection and tighten to specified torque settings.
