Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface, and raise the front of the vehicle using a jack and secure with jack stands.

2. Tire Inspection and Replacement

Check the tire condition:
- Remove the front left tire using a lug wrench.
- Inspect for bulges, punctures, or uneven wear.
If the tire is damaged:
- Replace with a new tire of the same specifications (e.g., size and type).

3. Brake Inspection

Remove the brake caliper:
- Use a socket wrench to remove the caliper bolts.
- Support the caliper with a bungee cord; do not let it hang by the brake line.
Inspect brake pads and rotor:
- Check for thickness of brake pads (should be at least 3mm).
- Inspect the rotor for grooves or warping.
Replace components if necessary:
- Install new brake pads and resurfaced or new rotors as needed.
- Reassemble the brake caliper and torque bolts to manufacturer specifications (typically 25-35 Nm).

4. Suspension Component Inspection

Inspect suspension components:
- Check control arms, bushings, and ball joints for wear or damage.
- Replace any worn components as necessary.
Reassemble any removed parts and torque to specifications.

5. Power Steering Check

Inspect power steering fluid:
- Check the level in the reservoir; top off with manufacturer-recommended fluid if low.
Inspect for leaks:
- Look for signs of leaking fluid around hoses and connections; replace any damaged hoses.

6. Wheel Bearing Check

Inspect wheel bearings:
- Rotate the front left wheel by hand; listen for grinding noises.
- If noise is present, remove the wheel and hub assembly to access the bearing.
Replace bearing if necessary:
- Use a bearing puller to remove the old bearing and install a new one, ensuring proper lubrication.
