Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Inspect and Replace CV Joints

Steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the outer CV joint boots for cracks or tears; replace if damaged.
4. If the CV joint is found to be faulty, remove the axle nut with a socket.
5. Disconnect the lower control arm from the steering knuckle to access the CV joint.
6. Remove the axle from the transmission side and replace with a new CV axle if needed.
7. Reassemble components in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically around 50-60 ft-lbs for axle nut).

3. Check and Replace Suspension Components

Steps:
1. Inspect control arms and bushings for wear; replace any damaged components.
2. Remove the control arm by unbolting it from the chassis and ball joint.
3. Replace with a new control arm and bushings if necessary, ensuring proper alignment.
4. Reattach the control arm and torque bolts to the manufacturer-specified torque.

4. Inspect Wheel Bearings

Steps:
1. Spin the wheel by hand and listen for any grinding noises indicating a faulty bearing.
2. If noise is present, remove the brake caliper and rotor to access the wheel bearing.
3. Remove the bearing using a bearing puller and replace with a new one.
4. Reassemble the brake components and wheel, ensuring proper torque specifications are followed.
