Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, torque wrench, OBD-II scanner, socket set.
Ensure the vehicle is on a level surface.
Disconnect the battery to avoid electrical issues while working on the steering system.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the control arms and bushings for any visible signs of wear or damage.
4. If any components are damaged, remove them by unscrewing the bolts with a socket set.
5. Install new components, ensuring to torque bolts to manufacturer specifications (refer to service manual for exact torque values).

3. Check and Replace CV Joints

Sub-steps:
1. Locate the CV joints on either side of the axle.
2. Inspect for tears in the rubber boot and any excessive play in the joint.
3. If damaged, remove the axle assembly from the vehicle.
4. Replace the CV joint or the entire axle assembly if necessary.
5. Reinstall the axle and secure with the appropriate torque specifications.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the brake caliper and rotor to access the wheel hub.
2. Inspect the wheel bearings for any signs of damage or excessive play.
3. If the bearings are worn, remove the hub assembly.
4. Press out the old bearings and press in the new ones.
5. Reassemble the hub, rotor, and caliper, ensuring all fasteners are torqued to specifications.
