Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during inspection.

2. Tire Inspection

Remove the hubcaps or wheel covers if necessary.
Check each tire for signs of uneven wear or bulges.
Rotate or replace tires if damage is found.

3. Wheel Bearing Inspection

Jack up the vehicle and secure it on jack stands.
Spin each wheel by hand and listen for grinding or roughness.
If noise is detected, remove the wheel and replace the wheel bearing as follows:
- Remove the brake caliper and rotor.
- Unbolt the wheel hub assembly and replace the bearing.
- Reassemble in reverse order, ensuring proper torque specifications for all fasteners.

4. Drivetrain and CV Joint Check

Inspect the CV joints for torn boots or leaks.
If damaged, replace the CV joint assembly as follows:
- Lift the vehicle and remove the wheel.
- Disconnect the lower control arm and remove the axle nut.
- Pull the axle out of the hub and replace the CV joint.
- Reassemble all components, ensuring correct torque values.

5. Transmission Fluid Check

Locate the transmission dipstick or fill port.
Check the fluid level and condition; it should be a bright red color and not burnt.
If low or dirty, drain the transmission fluid and replace it with the manufacturer's recommended fluid.
