Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Check Transmission Fluid

Tools Required: Transmission fluid dipstick, funnel
Remove the dipstick and wipe it clean.
Reinsert it and remove it again to check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
Inspect the fluid for burnt smell or debris; if found, a transmission service may be needed.

3. Inspect Drivetrain Components

Tools Required: Socket set, jack stands
Raise the vehicle and securely support it with jack stands.
Visually inspect the CV joints and axles for cracks or tears in the boots.
Check the wheel bearings by spinning the wheels; listen for any roughness or grinding.
If any components are damaged, replace them as necessary.

4. Address Wheel Bearings (if necessary)

Remove the wheel to access the hub.
Use a socket set to remove the hub assembly.
Replace any worn or damaged bearings with new ones.
Reinstall the hub assembly, ensuring proper torque specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery if it was disconnected.
Start the vehicle and perform a test drive to ensure the grinding noise is resolved.
