Solution

1. Preparation

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

2. Inspect and Replace Brake Components

Remove the wheel to access the brake caliper.
Inspect brake pads for wear; replace if less than 3 mm thick.
Check the rotor surface for scoring or warping; replace if necessary.
Lubricate the caliper slide pins and brake pad backing plates with anti-seize lubricant.
Reinstall the wheel and torque lug nuts to the manufacturer’s specifications.

3. Check and Replace Suspension Components

Inspect suspension bushings and joints for cracks or wear.
If worn, replace the bushings using a suitable press.
Check the struts for leakage; replace if necessary.
Reassemble the suspension components, ensuring all fasteners are tightened to specified torque.

4. Inspect and Adjust Drive Belt

Remove the drive belt by releasing tension using a belt tensioner tool.
Check the belt for cracks or fraying; replace if any damage is found.
Ensure proper alignment of the belt on all pulleys before reinstallation.
Reinstall the belt, ensuring proper tension is achieved.

5. Inspect Wheel Bearings

Raise the vehicle and support it securely on jack stands.
Spin the wheel by hand and listen for grinding or roughness.
If noise is present, remove the wheel and hub assembly, then replace the wheel bearing.
Reassemble the wheel and torque fasteners to specification.
