Removing a broken bolt from a hub can be a challenging task, but there are homemade solutions that you can try before seeking professional help. These methods involve using common tools and materials you might already have at home, such as penetrating oil, a drill, or an extractor kit. By following these steps, you can save time and money while effectively addressing the issue.

What Are the Steps to Remove a Broken Bolt from a Hub?

1. Assess the Situation

Before attempting any removal method, it’s essential to assess the situation:

• Visibility: Determine how much of the broken bolt is exposed.
• Condition: Check for rust or corrosion that might complicate removal.
• Tool Access: Ensure you have the necessary tools available.

2. Use Penetrating Oil

Penetrating oil can help loosen the bolt by reducing friction:

• Apply Oil: Spray a generous amount of penetrating oil onto the bolt and surrounding area.
• Wait: Allow the oil to penetrate for at least 15-30 minutes.
• Repeat if Necessary: In stubborn cases, reapply and let it sit overnight.

3. Try a Bolt Extractor

A bolt extractor can grip and remove the broken bolt:

• Drill a Hole: Use a drill bit slightly smaller than the extractor to create a hole in the center of the bolt.
• Insert Extractor: Place the extractor into the hole and turn counterclockwise.
• Apply Steady Pressure: Maintain steady pressure to avoid breaking the extractor.

4. Use Heat

Heat can expand the metal, making it easier to remove the bolt:

• Heat the Area: Use a propane torch to heat the area around the bolt.
• Avoid Direct Heat: Be careful not to overheat the bolt itself.
• Use a Wrench: Once heated, try turning the bolt with a wrench.

5. Welding a Nut

If other methods fail, welding a nut onto the bolt can provide a grip:

• Weld the Nut: Securely weld a nut onto the exposed part of the bolt.
• Cool Down: Allow the weld to cool.
• Turn the Nut: Use a wrench to turn the nut and remove the bolt.
