Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, wheel bearing puller, grease.
Safety Warnings: Ensure the vehicle is on a flat surface and use jack stands to secure it before working underneath.

2. Remove the Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove Brake Components

Sub-step 3.1: Remove the brake caliper by unbolting it from the caliper bracket.
Sub-step 3.2: Secure the caliper with a bungee cord or rope to avoid straining the brake line.
Sub-step 3.3: Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace Wheel Bearing

Sub-step 4.1: Inspect the wheel bearing for excessive play or roughness by shaking the hub assembly.
Sub-step 4.2: If replacement is needed, use a wheel bearing puller to remove the old bearing from the hub.
Sub-step 4.3: Clean the hub area and install the new bearing, making sure it fits snugly and is properly seated.

5. Reassemble Components

Sub-step 5.1: Reinstall the brake rotor and secure it with retaining screws.
Sub-step 5.2: Reattach the brake caliper and ensure it is bolted tightly.
Sub-step 5.3: Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Torque Lug Nuts

Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually 80-100 ft-lbs for Tesla).
