2. Inspect and Replace Damaged Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a lug wrench.
3. Inspect the control arms and bushings for cracks or excessive wear.
4. If damaged, remove the control arm bolts using a socket set, and replace with new parts.
5. Reinstall the control arms and torque the bolts to the manufacturer’s specifications.

3. Check and Replace CV Joints (if necessary)

Sub-steps:
1. If the CV joints show signs of wear, remove the axle nut using a socket set.
2. Detach the CV axle from the hub assembly using a pry bar if necessary.
3. Replace the CV joint with a new one, ensuring proper alignment.
4. Reassemble the axle and tighten the axle nut to the manufacturer’s torque specifications.

4. Inspect and Replace Wheel Bearings (if necessary)

Sub-steps:
1. If wheel bearings are suspected to be faulty, remove the brake caliper and rotor.
2. Use a socket set to remove the hub assembly.
3. Inspect the bearings; if they feel rough or have excessive play, replace them with new bearings.
4. Reassemble the hub, ensuring all components are properly torqued.
