Raise the vehicle and securely place it on jack stands.
Remove the front wheels to access suspension components.
Inspect control arms, bushings, and struts for wear.
Replace any damaged or worn components as necessary, torqueing bolts to manufacturer specifications.

4. Inspect and Replace CV Joints/Axles

Tools Required: CV joint removal tool, socket set.
Remove the wheel and brake assembly to access the axles.
