Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, socket set, brake cleaner.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle’s 12V battery to ensure safety during inspection.

2. Inspect and Clean Brake Components

Remove Wheels: Use a jack to lift the car and secure it with jack stands, then remove the wheels.
Inspect Brake Pads: Check brake pads for wear. Replace if they are worn down to indicators.
Clean Brake Components: Use brake cleaner to remove dust and debris from the brake pads and rotors.
Reassemble: Reinstall the wheels and lower the vehicle back to the ground.

3. Examine Suspension Components

Check Bushings and Joints: Look for cracks or wear in bushings and ball joints. Replace any that are damaged.
Lubricate Components: Apply appropriate lubricant to squeaky bushings and joints to reduce noise.
Test Suspension: Press down on the vehicle to check for any unusual sounds indicating worn suspension parts.

4. Inspect Drive Belts

Locate Drive Belts: Open the hood and visually inspect the drive belts for wear or damage.
Replace if Necessary: If the belts show signs of fraying or cracking, replace them with OEM-spec belts.
Check Tension: Ensure belts are properly tensioned according to manufacturer specifications.

5. Inspect Wheel Bearings

Lift Vehicle: Raise the vehicle and secure it with jack stands.
Check for Play: Grab the wheel at 12 and 6 o'clock and check for play in the wheel bearing.
Replace Bearings: If play is detected, remove the hub assembly and replace the wheel bearings.
