Solution

1. Preparation

Gather tools and materials:
- Jack and jack stands
- Socket set
- Torque wrench
- Brake cleaner
- Lubricant (grease or silicone spray)
Ensure the vehicle is parked on a level surface, and the engine is off.

2. Brake Component Inspection

Sub-steps:
1. Lift the front and rear of the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake components.
3. Inspect brake pads for wear; replace if thickness is below 3mm.
4. Check rotors for scoring or warping; replace if necessary.
5. Clean the brake pads and calipers with brake cleaner.
6. Apply lubricant to the back of the brake pads to prevent noise.

3. Suspension Component Inspection

Sub-steps:
1. Visually inspect all suspension components for cracks or excessive wear.
2. Use a pry bar to check for play in bushings and joints; replace any worn components.
3. Tighten any loose bolts to manufacturer torque specifications.

4. Serpentine Belt and Tensioner Replacement

Sub-steps:
1. Locate the serpentine belt and tensioner.
2. Release tension from the belt using a socket on the tensioner.
3. Remove the old serpentine belt and inspect the tensioner for wear.
4. Install a new serpentine belt and ensure proper routing.
5. Reapply tension and ensure the tensioner is functioning correctly.

5. Wheel Bearing Check

Sub-steps:
1. With the vehicle lifted, shake the wheel to check for play.
2. If play is detected, remove the wheel hub for further inspection.
3. Replace the wheel bearings if they show signs of wear or damage.
