1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Repair Brakes

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect the brake pads for thickness; replace if below 3mm.
3. Check the rotors for scoring; if damaged, replace or machine them.
4. Apply brake grease to the backing of the new pads to reduce noise.
5. Reinstall the wheel and torque to manufacturer specifications.

3. Inspect and Repair Suspension

Sub-steps:
1. Remove the wheel to access suspension components.
2. Inspect struts and shocks for leaks; replace if necessary.
3. Check control arms and bushings for play or deterioration; replace worn parts.
4. Reassemble the components and torque to manufacturer specifications.

4. Check Serpentine Belt and Pulleys

Sub-steps:
1. Locate the serpentine belt and examine for cracks or fraying.
2. Check the tensioner and idler pulleys for proper operation; replace if noisy.
3. If the belt is worn, remove it using a belt tensioner tool and replace it with a new belt.
4. Ensure all pulleys are aligned and functioning correctly.
