Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal if working on electrical components.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the front wheels using a socket set.
2. Inspect brake pads for thickness; replace if worn below manufacturer specification (typically 3mm or less).
3. If brake pads are worn, remove the caliper bolts using a torque wrench and slide the caliper off.
4. Remove old brake pads and install new pads, ensuring that the anti-squeal shims are in place.
5. Inspect the brake rotor surface for grooves or warping; replace if necessary.

3. Check Wheel Bearings

Sub-steps:
1. With the wheel still off, grab the brake rotor and check for play; any movement indicates a bad wheel bearing.
2. If bearings are loose or worn, remove the hub assembly according to the manufacturer's specifications.
3. Replace the wheel bearings using a proper bearing puller and press.
4. Reassemble the hub and rotor, ensuring all components are torqued to specification.

4. Inspect Suspension Components

Sub-steps:
1. Check the control arms, bushings, and struts for signs of wear or damage.
2. Replace any worn components using appropriate tools (e.g., ball joint separator, socket set).
3. Reassemble the suspension components and torque to manufacturer specifications.
