Everything You Need to Know About Changing a Hub Bearing

Hub bearings are an essential part of your vehicle's suspension system, allowing your wheels to spin smoothly and safely. However, over time, hub bearings can wear out and need to be replaced. If you're experiencing any of the following symptoms, it's important to have your hub bearings checked:

• A grinding or humming noise when driving
• A vibration in the steering wheel or floorboard
• Loose or wobbly wheels
• Uneven tire wear

If you're not comfortable replacing hub bearings yourself, it's best to take your vehicle to a mechanic. However, if you're confident in your abilities, here's a step-by-step guide on how to change a hub bearing:

Tools You'll Need:

• Jack and jack stands
• Lug wrench
• Socket set
• Torque wrench
• Hub bearing press
• New hub bearing

Step-by-Step Instructions:

1. Safety First

First and foremost, it's important to take safety precautions. Park your vehicle on a level surface and engage the parking brake. Place wheel chocks behind the wheels opposite the ones you're working on.

2. Remove the Wheel

Loosen the lug nuts on the wheel using a lug wrench, but do not remove them completely. Use a jack to raise the vehicle until the wheel is off the ground. Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the brake caliper and remove the bolts holding it in place. Carefully lift the caliper off the rotor and secure it out of the way with a bungee cord or zip tie.

4. Remove the Rotor

Remove the bolts holding the rotor in place and gently pull it off.

5. Remove the Axle Nut

Locate the axle nut in the center of the hub. Use a socket wrench to loosen and remove the nut.

6. Remove the Hub Bearing Assembly

Use a hub bearing press to carefully remove the hub bearing assembly from the spindle.

7. Clean the Spindle

Clean the spindle thoroughly to remove any dirt or debris.

8. Install the New Hub Bearing Assembly

Apply a thin layer of grease to the spindle and carefully press the new hub bearing assembly into place.

9. Install the Axle Nut

Install the axle nut onto the spindle and tighten it to the specified torque using a torque wrench.

10. Reinstall the Rotor, Brake Caliper, and Wheel

Place the rotor back onto the hub and secure it with the bolts. Reinstall the brake caliper and tighten the bolts. Put the wheel back on and tighten the lug nuts. Lower the vehicle to the ground and torque the lug nuts to the specified torque.
