Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, wheel chock, safety glasses, gloves.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Raise the Vehicle

Use the jack to lift the front or rear of the Tacoma, depending on which wheel bearings need inspection.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Using the lug wrench, loosen and remove the lug nuts.
Remove the wheel to access the hub assembly.

4. Inspect the Wheel Bearing

Visual Inspection: Look for any signs of rust or damage on the bearing seal.
Check for Play: With the wheel off, grab the hub and check for excessive play (more than 1/8 inch).
Spin Test: Rotate the hub by hand; it should spin smoothly without grinding or rough spots.

5. Replace Wheel Bearing (if necessary)

If the bearing is bad, proceed with removal:
- Remove the brake caliper and bracket (if applicable).
- Remove the dust cap, cotter pin, and nut retaining the bearing.
- Use a bearing puller or slide hammer to remove the bearing from the hub.
- Install the new bearing by reversing the steps, ensuring proper torque on the retaining nut (usually around 50-75 ft-lbs).
