Remove the front wheels to access the CV joints.
Inspect the CV boots for tears or leaks; replace if necessary.
Check the CV joints for excessive play or damage; replace if worn.

4. Check Wheel Bearings

Spin the wheel by hand and listen for any grinding noises.
Check for lateral play by grabbing the wheel at 12 and 6 o'clock; replace the wheel bearings if any play is detected.

5. Inspect Suspension Components

Visually inspect control arms, bushings, and tie rod ends for any signs of wear.
Replace any damaged or worn components.
Reassemble the wheel and lower the vehicle.
