Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working.

2. Inspect and Replace Transmission Fluid

Tools Required: Transmission fluid pump, socket set, drain pan, funnel.

Reinstall the drain plug and torque to the manufacturer's specifications.
Use the fluid pump to fill the transmission with the recommended fluid type, checking the level with the dipstick.

3. Inspect and Replace Drive Shafts or CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar.
Lift the vehicle using jack stands for safety.
Remove the wheel to access the CV joint and drive shaft.
Inspect the CV boots for cracks or leaks; if damaged, replace the entire CV joint or drive shaft.
Reinstall the wheel and torque to the manufacturer's specifications.

4. Test Drive and Final Checks

Reconnect the battery and start the vehicle.
Drive the vehicle under similar conditions to replicate the noise to ensure it has been resolved.
