Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection

Tools Required: Tire pressure gauge, visual inspection tools.
Check each tire for uneven wear patterns; replace if necessary.
Verify that all tires are inflated to the manufacturer’s recommended pressure.

3. Wheel Bearing Replacement (if faulty)

Tools Required: Socket set, torque wrench, pry bar.
Lift the vehicle and securely support it with jack stands.
Remove the wheel from the side with the grinding noise.
Disconnect the brake caliper and rotor to access the wheel hub.
Remove the wheel hub assembly bolts, and carefully extract the hub from the bearing.
Replace the bearing with a new one, ensuring it is properly seated.
Reassemble the wheel hub and torque all bolts to manufacturer specifications (consult service manual for specific values).

4. CV Joint Inspection and Replacement (if needed)

Tools Required: Socket set, CV joint puller, grease.
Inspect the CV joint boots for cracks or tears; replace if damaged.
If the CV joint is damaged, remove the axle from the wheel hub and transmission.
Replace the CV joint assembly and apply fresh grease.
Reinstall the axle and torque to specified values.

5. Suspension Component Repair (if necessary)

Tools Required: Socket set, torque wrench, pry bar.
