Solution

1. Preparation

Gather tools and parts as listed below.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during inspection.

2. Check Transmission Fluid

Remove the transmission dipstick and check the fluid level.
If low, add the appropriate transmission fluid (refer to the owner's manual for specifications).
If the fluid is dark or has a burnt smell, consider a fluid change.

3. Inspect Drivetrain Components

Raise the vehicle using a jack and secure it with jack stands.
Visual inspection of the driveshaft and CV joints for any signs of wear or damage.
Rotate the driveshaft by hand to feel for any unusual resistance or noise.

4. Test Wheel Bearings and Axles

Spin each wheel by hand to check for smoothness and listen for any abnormal noises.
Inspect the wheel bearings for play by shaking the wheels while grasping at the 12 and 6 o’clock positions.

5. Addressing Issues

If transmission fluid is low, refill it and monitor for leaks.
Replace any damaged CV joints or wheel bearings using appropriate replacement parts.
If necessary, consult a professional for transmission service if the noise persists.
