Safety warning: Wear safety goggles and gloves during the repair process.

2. Inspect and Replace Damaged CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench, CV joint puller (if necessary)
Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the wheel on the affected side.
Inspect the CV joint boots for tears or leaks. If damaged, proceed to replace the CV joint.
Remove the axle nut using a socket wrench. If necessary, use a CV joint puller to detach the axle from the hub.
Replace the CV joint with a new one, ensuring proper alignment and secure it with the axle nut, tightening to the manufacturer’s specified torque value.

3. Replace Worn Suspension Components

Tools Required: Socket set, wrench set, torque wrench
Inspect the control arms, tie rods, and bushings for wear.
If any components are worn, remove the affected parts by unbolting them from the chassis and steering knuckle.
Install new suspension components, ensuring all bolts are tightened to the manufacturer's specified torque values.

4. Check Wheel Bearings

Tools Required: Bearing puller, socket set, grease
Remove the wheel and brake caliper to access the wheel bearing assembly.
Inspect the wheel bearing for excessive play or noise.
If bearing is faulty, remove it using a bearing puller and install a new wheel bearing. Apply grease as per the manufacturer's specifications.
