Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Wheel Bearings

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the wheel bearing for play by shaking the wheel back and forth.
4. If the bearing is worn, remove the brake caliper and rotor.
5. Use a socket set to remove the wheel hub assembly.
6. Replace the wheel bearing with a new one, ensuring proper alignment.
7. Reinstall the hub assembly, brake rotor, and caliper. Torque to manufacturer specifications.

3. Replace Worn Brake Components

Sub-steps:
1. If grinding noise is present, remove the wheel as previously described.
2. Inspect brake pads for thickness; replace if below manufacturer's minimum thickness.
3. Check the rotor for scoring or warping; replace if necessary.
4. Install new brake pads and reassemble the braking system.
5. Bleed the brakes if required.

4. Repair or Replace Suspension Components

Sub-steps:
1. Check for play in control arms and bushings; replace any worn parts.
2. If shocks or struts are worn, remove them by detaching the upper and lower mounts.
3. Install new shocks or struts, ensuring they are torqued to specifications.
4. Reassemble any removed components and lower the vehicle.
