Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, stethoscope (for noise location).
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool if it has been running.

2. Inspect Brake System

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if worn below 3mm.
3. Check brake rotors for scoring or warping; replace if necessary.
4. Clean the brake components with brake cleaner to remove dust.
5. Reinstall the wheel and torque to manufacturer specifications (typically around 76 lb-ft for Toyota Camry).

3. Inspect Drive Belts

Sub-steps:
1. Open the hood and visually inspect the serpentine belt for cracks or wear.
2. Use a stethoscope to listen for any noise from the belt area while the engine is running.
3. Replace the belt if it is damaged or making noise.
4. Ensure proper tension is maintained on the belt.

4. Check Wheel Bearings

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Grab the wheel at 12 and 6 o'clock positions and wiggle to check for play.
3. If there is play, remove the wheel and inspect the bearing hub for damage.
4. Replace any worn wheel bearings, following manufacturer torque specifications for reassembly.

5. Inspect Suspension Components

Sub-steps:
1. Visually inspect shock absorbers and struts for leaks or damage.
2. Check control arms, bushings, and ball joints for wear.
3. Replace any damaged suspension parts as needed.
