Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if necessary to avoid electrical issues.

2. Inspect and Replace Wheel Bearings

Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Wheel Bearing:
- Spin the hub by hand to check for smoothness.
- Listen for any grinding or roughness.
Remove Old Bearing: If defective, use a bearing puller to remove the old wheel bearing.
Install New Bearing:
- Apply grease to the new wheel bearing.
- Press the new bearing into the hub using a bearing press.
Reassemble:
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs for RAV4).
- Lower the vehicle.

3. Inspect and Replace CV Joints (if necessary)

Check CV Boots: Inspect for cracks or tears in the CV boots.
Remove CV Axle:
- Remove the axle nut (use a breaker bar if necessary).
- Disconnect the lower control arm if needed to free the axle.
Replace CV Joint: If damaged, remove the old CV joint from the axle and install a new one.
Reassemble: Reattach the axle and torque the nut to specifications.

4. Transmission and Differential Fluid Check

Check Fluid Levels:
- Locate the transmission and differential fill plugs.
- Remove the plugs and ensure fluid is at the proper level.
Replace Contaminated Fluid: If fluid is dirty or low, drain and refill with the correct type of transmission and differential fluids.
