Main points
- Place the hub assembly on the press base with the inner race facing the ram.
- Use the hydraulic press and the same adapter to press the new inner race into the hub.
- Trying to remove the race with a hammer and punch can damage the hub or the race itself.
Replacing a wheel bearing is a common maintenance task for car owners. While the process can seem daunting, it’s a manageable challenge with the right tools and knowledge. One of the trickiest parts of this job is removing the inner wheel bearing race, the hardened steel ring that sits inside the hub. This post will guide you through the process of removing the inner wheel bearing race, providing clear instructions and helpful tips.
Gathering Your Arsenal: Essential Tools
Before you dive into the removal process, ensure you have the following tools:
- Hydraulic press: This is the most effective tool for removing the inner race.
- Bearing race remover set: This set includes various sized tools specifically designed for removing bearing races.
- Hammer and punch: These are helpful for loosening the race if it’s stuck.
- Torque wrench: Essential for tightening the hub nut back to the correct specifications.
- Protective gear: Wear safety glasses, gloves, and appropriate footwear to protect yourself from potential hazards.
Preparing the Battlefield: Disassembling the Hub
1. Secure the vehicle: Park the vehicle on a level surface and engage the parking brake. Chock the rear wheels for added safety.
2. Remove the wheel: Loosen the lug nuts with a breaker bar before jacking up the vehicle. Remove the wheel once it’s safely off the ground.
3. Remove the brake caliper: Remove the caliper bolts and carefully hang the caliper out of the way with a wire or bungee cord.
4. Remove the rotor: Remove the rotor bolts and carefully remove the rotor.
5. Remove the hub nut: Depending on your vehicle, you may need to use a special tool to hold the hub while you loosen the nut.
The Moment of Truth: Removing the Race
1. Positioning the Press: Place the hydraulic press on a sturdy workbench with the ram facing upwards.
2. Attaching the Adapter: Choose the appropriate adapter from your bearing race remover set that fits snugly against the inner race. Secure the adapter to the press ram.
3. Centering the Hub: Place the hub assembly on the press base with the inner race facing the ram. Ensure the adapter is centered and firmly against the race.
4. Applying Pressure: Slowly apply pressure to the press ram. The inner race should start to move out of the hub.
5. Persistence is Key: If the race is stubborn, you can use a hammer and punch to tap the adapter lightly. However, be careful not to damage the hub.
6. Complete Removal: Continue applying pressure until the inner race is completely removed from the hub.
Inspecting the Battlefield: Assessing the Hub
Once the inner race is removed, inspect the hub for any damage or wear. If the hub shows signs of damage, you may need to replace it.
Cleaning Up the Battlefield: Prepping for Installation
Thoroughly clean the hub assembly and the new inner race. Use a wire brush to remove any rust or debris. Apply a thin layer of grease to the new inner race before installing it.
The Final Stand: Installing the New Race
1. Pressing the New Race: Use the hydraulic press and the same adapter to press the new inner race into the hub. Make sure the race is properly seated and flush with the hub.
2. Reassembling the Hub: Reinstall the rotor, brake caliper, and wheel in reverse order. Torque the hub nut to the manufacturer’s specifications.
3. Final Inspection: Check that the wheel spins freely and there are no noises coming from the bearing.
Victory is Sweet: Completing the Mission
You’ve successfully removed the inner wheel bearing race and installed a new one. Give yourself a pat on the back! Remember to always follow proper safety procedures and use the right tools for the job.
Popular Questions
Q: Can I remove the inner race without a press?
A: While it’s technically possible to remove the race using other methods, a hydraulic press is the safest and most effective option. Trying to remove the race with a hammer and punch can damage the hub or the race itself.
Q: What if the race is stuck and won’t budge?
A: If the race is stuck, try using a hammer and punch to tap the adapter lightly. You can also try heating the hub with a torch, but be careful not to overheat it. If the race is still stuck, you may need to take it to a mechanic.
Q: How often should I replace my wheel bearings?
A: Wheel bearings typically last 50,000 to 100,000 miles. However, factors such as driving conditions and maintenance habits can affect their lifespan. If you hear any noises coming from your wheel bearings or notice any play in the wheel, it’s time to replace them.
Q: Can I reuse the old hub nut?
A: It’s generally recommended to replace the hub nut when replacing the wheel bearing. The nut is designed to stretch slightly during installation, and reusing it can compromise its ability to secure the hub properly.
Q: What are the signs that my wheel bearing needs replacing?
A: Some common signs of a failing wheel bearing include:
- Grinding or rumbling noise: This sound usually gets louder as the bearing wears down.
- Clicking or popping sound: This sound is often heard when turning the steering wheel.
- Vibrating steering wheel: A worn-out bearing can cause the steering wheel to vibrate, especially at highway speeds.
- Loose or wobbly wheel: This indicates that the bearing has worn out and is no longer holding the wheel securely in place.
By following these steps and being mindful of the potential challenges, you can successfully remove the inner wheel bearing race and get your vehicle back on the road. Remember, safety should always be your top priority, and if you’re unsure about any part of the process, it’s best to consult a professional.
