Solution

1. Preparation

Gather tools including a jack, jack stands, socket set, and torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle at the designated lift points.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Components

A. Inspection

Check for debris in the wheel well and remove it if found.
Examine tire condition:
- Look for uneven wear; replace tires if necessary.
Inspect suspension components:
- Look for damaged bushings, struts, or shocks.

B. Wheel Bearing Replacement (if needed)

Remove the wheel using a socket set.
Remove the brake caliper and rotor for access to the wheel hub.
Remove the wheel hub assembly by unbolting it from the knuckle.
Replace the wheel bearing using a bearing press if necessary.
Reassemble in reverse order, ensuring all bolts are torqued to manufacturer specifications.

C. CV Joint Replacement (if needed)

Remove the wheel and axle nut.
Detach the lower control arm or suspension component as needed.
Pull the axle out of the transmission and inspect the CV joint.
Replace the CV joint if it shows signs of damage; reassemble components in reverse order.
