Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Remove the wheel using the lug wrench.
Inspect brake pads and rotors for wear. If pads are below 3mm thickness or rotors are scored, replace them.
- Sub-steps:
  - Remove the caliper bracket bolts using a socket.
  - Slide the caliper off the rotor and secure it with a bungee cord.
  - Remove the old brake pads.
  - Install new brake pads and reassemble the caliper.
  - Torque caliper bracket bolts to specification (typically 79 ft-lbs for RAV4).
Reinstall the wheel and lower the vehicle.

3. Inspect and Replace Wheel Bearings

Tools Required: Jack and jack stands, socket set, bearing puller (if necessary).
Jack up the vehicle and remove the wheel.
Check for any play in the wheel bearing by shaking the wheel.
- If bearing is worn, remove the hub assembly and replace the bearing.
- Sub-steps:
  - Use a bearing puller to extract the old bearing.
  - Press in the new bearing ensuring it's seated properly.
Reassemble and torque the hub assembly bolts.

4. Check Transmission Fluid

Tools Required: Transmission fluid dipstick or funnel.
Check the transmission fluid level using the dipstick; top off if low.
If fluid is burnt or contaminated, consider a transmission fluid change.
