Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Wheel Bearings

Tools Required: Socket set, torque wrench, wheel bearing puller, grease.
Lift the front of the vehicle using a jack and secure it with jack stands.
Remove the wheel by loosening the lug nuts and setting it aside.
Remove the brake caliper and rotor to access the wheel bearing.
Use a wheel bearing puller to extract the old bearing from the hub.
Clean the hub area and apply new grease to the new bearing.
Install the new bearing and reassemble the components in reverse order, ensuring proper torque specifications for the lug nuts (typically 75-85 ft-lbs for most RAV4 models).

3. Inspect and Replace CV Joints (if necessary)

Tools Required: Socket set, CV joint removal tool.
With the vehicle still lifted, inspect the CV joints for any torn boots or visible damage.
If damaged, remove the axle shaft by disconnecting the lower control arm and the hub assembly.
Use a CV joint tool to separate the joint from the axle and replace it with a new one.
Reassemble the axle and ensure all bolts are torqued to manufacturer specifications.
