Remove the wheel to access the CV joint.
Inspect the CV boot for tears or grease leaks.
Remove the CV joint if damaged, using a socket set to detach it from the axle.
Install a new CV joint, ensuring proper torque specifications are met.

4. Replace Wheel Bearings (if worn)

Remove the wheel and brake caliper for access.
Detach the hub assembly from the steering knuckle.
Use a bearing puller to remove the old wheel bearing.
Install a new wheel bearing and reassemble the hub assembly, ensuring proper torque.

5. Inspect and Replace Suspension Components (if necessary)

Check struts and bushings for wear.
Use a socket set to remove any worn components.
Install new struts or bushings, following manufacturer torque specifications.
