Remove the front wheels for better access to the CV joints.
Inspect the CV boots for tears or leaks; replace if necessary.
Check the CV joints for play; if damaged, replace the entire axle assembly.

4. Examine Suspension Components

Tools Required: Torque wrench, socket set
Inspect control arms and bushings for wear or damage.
Check struts for leaks or signs of wear; replace if necessary.
Retighten any loose suspension bolts to manufacturer specifications.
