Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Engage the parking brake and wear safety glasses.

2. Brake Inspection

Tools Required: Socket set, brake cleaner, torque wrench
Remove the wheel to access the brake components.
Inspect brake pads for wear; replace if thickness is less than 3 mm.
Check the brake rotors for scoring or damage; replace if necessary.
Clean the brake components with brake cleaner and reassemble the wheel, torquing lug nuts to the manufacturer’s specifications.

3. Serpentine Belt Inspection

Tools Required: Belt tensioner tool
Remove the belt by releasing tension using the belt tensioner tool.
Inspect the belt for cracks, fraying, or glazing; replace if any damage is found.
Check the pulleys for alignment and wear; replace any damaged components.

4. Suspension Component Inspection

Tools Required: Jack, jack stands, torque wrench
Raise the vehicle and secure it on jack stands.
Visually inspect all suspension components, including struts, bushings, and control arms for signs of wear or damage.
Replace any worn or damaged bushings or struts.

5. Wheel Bearing Inspection

Tools Required: Socket set, torque wrench
Remove the wheel and inspect the wheel hub for play by wiggling it.
If play is detected, replace the wheel bearing assembly according to the manufacturer’s specifications.
