Replacing a rear wheel bearing on a bike is a task that requires some skill and knowledge, but it’s not impossible to do at home. With the right tools and a little patience, you can get the job done in a few hours.

What You’ll Need

Before you start, you’ll need to gather the following tools and materials:

• New rear wheel bearing
• Cone wrench
• Lockring wrench
• Grease
• Rags
• Chain whip (optional)
• Spoke wrench (optional)
• Hammer (optional)
• Drift punch (optional)

Step-by-Step Instructions

1. Remove the Wheel

Start by removing the rear wheel from the bike. To do this, flip the bike upside down and loosen the axle nuts using a cone wrench. Once the nuts are loose, you can pull the wheel straight out of the frame.

2. Remove the Lockring

Once the wheel is removed, you’ll need to remove the lockring that holds the cassette in place. To do this, use a lockring wrench to loosen the lockring. Be careful not to damage the lockring or the cassette.

3. Remove the Cassette

Once the lockring is removed, you can remove the cassette. To do this, use a chain whip to hold the cassette in place while you unscrew the cassette lockring using a cassette tool. Once the lockring is removed, you can pull the cassette straight off the hub.

4. Remove the Old Bearing

With the cassette removed, you can now access the old bearing. To remove the old bearing, use a hammer and drift punch to tap it out of the hub. Be careful not to damage the hub.

5. Install the New Bearing

Once the old bearing is removed, you can install the new bearing. To do this, simply press the new bearing into the hub by hand. Be sure to apply a thin layer of grease to the bearing before installing it.

6. Reinstall the Cassette

Once the new bearing is installed, you can reinstall the cassette. To do this, simply slide the cassette onto the hub and tighten the cassette lockring using a cassette tool. Be sure to torque the lockring to the manufacturer’s specifications.

7. Reinstall the Lockring

Once the cassette is installed, you can reinstall the lockring. To do this, simply screw the lockring onto the hub by hand and then tighten it using a lockring wrench. Be sure to torque the lockring to the manufacturer’s specifications.

8. Reinstall the Wheel

Once the lockring is installed, you can reinstall the wheel. To do this, simply insert the wheel into the frame and tighten the axle nuts using a cone wrench. Be sure to torque the axle nuts to the manufacturer’s specifications.

Tips

• If you’re not comfortable removing the cassette, you can take the wheel to a bike shop and have them do it for you.
• Be sure to apply a thin layer of grease to all of the bearings and moving parts.
• If you’re having trouble removing the old bearing, you can try using a penetrating oil.
• Be patient and take your time. Replacing a rear wheel bearing is not a difficult task, but it does require some care and attention to detail.
