Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Wheel Bearing

Check Bearing Play: Grasp the wheel at the 12 and 6 o'clock positions and wiggle to check for any movement indicating worn bearings.
Inspect Dust Seal: Examine the dust seal for any signs of leakage or damage.

4. Replace Wheel Bearing (if necessary)

Remove Brake Caliper: Unbolt and remove the brake caliper using a socket set. Secure it to the suspension with a bungee cord to avoid straining the brake line.
Remove Rotor: Take off the brake rotor by unbolting it from the hub.
Detach Hub Assembly: Unbolt the hub assembly and carefully remove it from the knuckle.
Install New Bearing: Press the new wheel bearing into the hub assembly using a bearing press.
Reassemble Components: Reattach the hub assembly, rotor, and caliper in reverse order. Ensure all bolts are torqued to manufacturer specifications.

5. Reattach Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to the specified torque.
