Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.
Wear safety glasses and gloves.

2. Inspect and Replace Steering Components

Steering Inspection:
- Use a socket set to remove the wheel covers and tires to gain access to the steering components.
- Check tie rods and ball joints for play by shaking them manually.
Replacement:
- If any components are worn, use a ball joint separator to detach the old parts.
- Install new tie rods or ball joints, ensuring they are torqued to manufacturer specifications (check service manual for torque values).

3. Inspect and Replace Suspension Components

Suspension Inspection:
- Visually inspect control arms and bushings for cracks or excessive wear.
Replacement:
- Use a wrench to remove the bolts securing the control arms.
- Replace worn bushings with new ones, applying grease if required, and reattach the control arms securely.

4. Check Wheel Bearings

Inspection:
- Spin the wheel and listen for abnormal noise.
Replacement:
- If the bearing is faulty, remove the wheel, then the brake caliper and rotor.
- Use a bearing puller to remove the old bearing and press in a new one.

5. Inspect CV Joints

Inspection:
- Check the CV joint boots for tears or grease leaks.
Replacement:
- If damaged, remove the CV axle using a socket set.
- Replace with a new CV axle, ensuring it is correctly seated in the differential and the wheel hub.
