Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a flat surface and engage the parking brake.

2. Inspect and Replace CV Joints

Sub-steps:
1. Lift the front of the vehicle and secure with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joint boots for tears. If damaged, proceed to replace the CV joint.
4. Remove the axle nut and disconnect the CV joint from the hub.
5. Replace the CV joint and reassemble in reverse order, ensuring the axle nut is torqued to the manufacturer's specification (usually around 150-200 ft-lbs).

3. Inspect and Replace Suspension Components

Sub-steps:
1. Use a pry bar to check for play in control arm bushings and ball joints.
2. If any components are worn, disconnect the affected parts.
3. Replace worn bushings or ball joints following the vehicle's service manual for torque specifications during reassembly.
4. Reattach the components and ensure all fasteners are tightened to specification.

4. Verify Wheel Bearing Condition

Sub-steps:
1. Spin the wheel while it's off the ground to listen for grinding noises.
2. If noise is present, remove the wheel bearing and replace it.
3. Apply grease to the new bearing and install it according to the manufacturer's recommendations.
