Changing a wheel bearing can be a moderately difficult task, especially if you haven’t done it before. It requires some mechanical knowledge and the right tools. Here’s a step-by-step guide to help you through the process:
Tools and Materials Needed:
• Jack and jack stands
• Lug wrench
• Socket set and wrenches
• Hammer and punch
• Torque wrench
• Wheel bearing kit (specific to your vehicle)
• Brake cleaner
• Grease or bearing lubricant
• Pry bar (optional)
• Safety gloves and goggles
Step-by-Step Guide:
1. Safety First:
• Park the car on a level surface.
• Engage the parking brake and chock the wheels that aren’t being worked on.
• Wear safety gloves and goggles.
2. Loosen the Lug Nuts:
• Slightly loosen the lug nuts on the wheel before lifting the vehicle. Don’t remove them entirely yet.
3. Lift the Vehicle:
• Use a jack to lift the vehicle and secure it on jack stands.
• Make sure the vehicle is stable before you proceed.
4. Remove the Wheel:
• Fully remove the lug nuts and take off the wheel.
5. Remove the Brake Caliper and Rotor:
• Unbolt the brake caliper and hang it with a bungee cord or wire to avoid straining the brake line.
• Remove the brake rotor (this might require a few taps with a rubber mallet if it’s stuck).
6. Remove the Dust Cap, Cotter Pin, and Nut:
• Remove the dust cap from the center of the hub.
• Take out the cotter pin that secures the hub nut.
• Use a wrench to remove the nut.
7. Detach the Hub Assembly:
• Depending on your vehicle, you might have a hub assembly with a pressed-in bearing or a separate bearing that can be replaced.
• If it’s a hub assembly, remove the bolts that secure it to the steering knuckle.
• For pressed-in bearings, you might need a bearing press kit to remove it.
8. Remove the Old Bearing:
• Use a hammer and punch to tap out the old bearing (if it’s not a sealed unit).
• Clean the area thoroughly with brake cleaner to remove any debris or old grease.
9. Install the New Bearing:
• Grease the new bearing with the specified lubricant.
• Carefully press the new bearing into place using a bearing press or appropriate tool.
• Make sure the bearing is seated properly and evenly.
10. Reassemble the Hub Assembly:
• If you removed the hub, reinstall it back onto the steering knuckle and secure it with the bolts.
• Put the hub nut back on and tighten it to the specified torque value (check your vehicle’s manual for the correct torque specification).
• Install the new cotter pin and replace the dust cap.
11. Reinstall the Brake Components:
• Put the rotor back on.
• Reattach the brake caliper.
12. Put the Wheel Back On:
• Mount the wheel back onto the hub and hand-tighten the lug nuts.
• Lower the vehicle back to the ground.
13. Torque the Lug Nuts:
• Once the vehicle is on the ground, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
14. Test the Vehicle:
• Test drive your vehicle at low speeds to make sure everything is properly aligned and there are no unusual noises.
Important Tips:
• Consult Your Vehicle’s Manual: Each vehicle has its specific torque settings and procedures. Make sure to follow these to avoid damaging components.
• Check for Damage: While you’re working on the wheel bearing, inspect other parts like the CV joint, tie rod, and ball joints for any wear or damage.
• Use Quality Parts: Use a good-quality wheel bearing and always replace both sides if one side has gone bad, as they tend to wear out at similar rates.
Changing a wheel bearing can be time-consuming and requires the right tools. If you’re unsure or don’t have access to a bearing press, consider taking your car to a professional.
