Remove the wheel to gain access to the CV joint.
Remove the axle nut and split the joint from the transmission.
Replace with a new CV joint, ensuring proper alignment and securing the axle nut to the specified torque.

4. Inspect and Replace Suspension Components

Check the struts for leaks or damage; replace if necessary.
Examine control arms and bushings for wear; replace any damaged components.
Reassemble all components and ensure proper torque specifications are met.
