⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Disconnect the battery before working on electrical components.

Symptoms

•Grinding or humming noise that increases with vehicle speed
•Noise that changes or disappears when turning
•Vibration felt in the steering wheel or floor
•Uneven tire wear
•ABS warning light illuminated (if equipped)

Diagnostic Steps

1
Conduct a visual inspection of the wheels and tires for any signs of damage or uneven wear.
2
Lift the vehicle using a jack and secure it with jack stands; spin each wheel by hand to listen for noise.
3
Place a hand on the wheel hub while spinning the wheel to feel for vibrations or roughness.
4
Use a stethoscope or mechanic's listening device to isolate the noise source by placing it near the wheel bearings.
5
Check for play in the wheel bearings by grabbing the top and bottom of the wheel and shaking it; excessive movement indicates bearing wear.
6
Inspect the brake components and CV joints for any potential noise sources.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.
Disconnect the negative battery terminal to ensure electrical safety.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle with a jack and secure with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Wheel Bearings

Inspection:
- Visually examine the wheel hub for damage or excessive rust.
- Check the condition of the wheel bearing seals for wear or leakage.
Replacement:
- Using a wheel bearing press or puller, remove the old bearing from the hub.
- Clean the hub and apply a light coat of grease.
- Install the new bearing into the hub using the press, ensuring it is seated properly.
- Reinstall the bearing seal securely.

4. Reassemble Wheel and Components

Place the wheel back onto the hub, aligning the holes with the lug bolts.
Hand-tighten the lug nuts and lower the vehicle to the ground.
Tighten the lug nuts to the manufacturer’s specified torque (typically around 76 lb-ft for most RAV4 models).

5. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle completely and perform a final inspection to ensure everything is secure.
