Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel by loosening the lug nuts with a socket set and lifting the vehicle with a jack.
2. Inspect the brake pads for wear; if worn below the minimum thickness, replace them.
3. Check the brake rotors for scoring or warping; replace if necessary.
4. Reassemble the brake components using a torque wrench to tighten lug nuts to the manufacturer’s specifications (typically around 100 Nm).

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel again if it was replaced.
2. Remove the brake caliper and rotor to access the wheel bearing.
3. Inspect the wheel bearing for play; if damaged, replace it with a new bearing.
4. Reassemble the components, ensuring proper torque specifications.

4. Check and Tighten Suspension Components

Sub-steps:
1. Inspect all suspension components, including control arms and bushings, for wear.
2. Tighten any loose bolts to the manufacturer’s torque specifications.
3. Replace any damaged bushings or components as needed.
