Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Check the condition of brake rotors; replace if warped or scored.
4. Reassemble the brake components and reinstall the wheel.
5. Torque lug nuts to manufacturer specifications (typically 76 ft-lbs for Camry).

3. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick to check fluid level and condition.
2. If low or discolored, drain the old fluid using a fluid pump.
3. Replace with the manufacturer-recommended fluid (Toyota ATF WS).
4. Recheck fluid levels after refilling.

4. Inspect and Replace CV Joints or Axles

Sub-steps:
1. Lift the vehicle and securely support it on jack stands.
2. Inspect the CV joints for torn boots or grease leakage.
3. If damaged, remove the axle nut and disconnect the CV axle from the transmission and wheel hub.
4. Install the new CV axle and tighten the axle nut to manufacturer specifications (typically 130 ft-lbs).
5. Reassemble components and lower the vehicle.

5. Inspect Wheel Bearings

Sub-steps:
1. Lift the vehicle and spin the wheel to listen for grinding sounds.
2. If noise is present, remove the wheel and hub assembly.
3. Check the wheel bearings for play; replace if necessary.
4. Reassemble the hub and wheel, ensuring proper torque.
