While it might seem daunting, replacing a rear wheel bearing on your Outlander is a DIY project that can save you money and give you a sense of accomplishment. This guide will walk you through the entire process, step by step, providing you with the knowledge and confidence to tackle this repair.

Gather Your Tools and Materials

Before diving into the repair, make sure you have all the necessary tools and materials. This will ensure a smooth and efficient process.

• Jack and jack stands: To safely lift the vehicle.
• Lug wrench: To loosen and tighten the lug nuts.
• Torque wrench: To tighten the lug nuts to the correct specifications.
• Hammer: To remove the old bearing.
• Bearing race remover/installer: To remove and install the bearing races.
• Pry bar: To help remove the old bearing.
• Grease: To lubricate the new bearing.
• New rear wheel bearing: Ensure you purchase the correct bearing for your specific Outlander model and year.
• Safety glasses and gloves: For eye and hand protection.

Preparing Your Mitsubishi Outlander

Once you have gathered your tools and materials, it’s time to prepare your Mitsubishi Outlander for the repair.

1. Park on a level surface: This ensures stability and prevents the vehicle from rolling during the repair.
2. Engage the parking brake: This will further secure the vehicle and prevent accidental movement.
3. Chock the front wheels: Place wheel chocks in front of the front tires to prevent the vehicle from rolling backward.
4. Locate the rear wheel bearing: The rear wheel bearing is located within the hub assembly, which is attached to the rear wheel.
5. Remove the wheel: Use the lug wrench to loosen the lug nuts while the vehicle is still on the ground. Once the lug nuts are loose, raise the vehicle using the jack and place jack stands under the frame, ensuring the vehicle is securely supported. Now, remove the wheel completely.

Removing the Old Rear Wheel Bearing

With the wheel removed, you can now access the rear wheel bearing.

1. Remove the brake caliper: Use a wrench to loosen the caliper mounting bolts and carefully remove the caliper. Be sure to hang the caliper safely using a piece of wire to prevent stress on the brake hose.
2. Remove the brake rotor: The brake rotor is attached to the hub assembly. Use a hammer and a pry bar to separate the rotor from the hub.
3. Remove the hub assembly: The hub assembly is held in place by a nut on the axle shaft. Use a wrench to loosen and remove the nut. The hub assembly can now be pulled off the axle shaft.
4. Remove the old bearing: Once the hub assembly is removed, you can access the old bearing. Use a bearing race remover/installer to remove the inner and outer races from the hub assembly. You can then use a hammer and pry bar to remove the bearing itself.

Installing the New Rear Wheel Bearing

With the old bearing removed, you can now install the new one.

1. Clean the hub assembly: Thoroughly clean the hub assembly, removing any debris or rust.
2. Install the new races: Use the bearing race remover/installer to install the new inner and outer races into the hub assembly. Make sure they are seated properly and flush with the hub.
3. Install the new bearing: Carefully press the new bearing into the hub assembly. Ensure it is fully seated and flush with the hub.
4. Lubricate the new bearing: Apply a generous amount of grease to the new bearing to ensure smooth operation.
5. Reassemble the hub assembly: Reinstall the hub assembly onto the axle shaft and tighten the nut to the correct specifications.
6. Reinstall the brake rotor: Carefully slide the brake rotor back onto the hub assembly.
7. Reinstall the brake caliper: Reattach the brake caliper to the hub assembly and tighten the mounting bolts.
8. Reinstall the wheel: Reinstall the wheel and tighten the lug nuts to the correct torque specifications using the torque wrench.

Final Steps and Testing

You’re almost there! Just a few final steps to complete the repair.

1. Lower the vehicle: Carefully lower the vehicle using the jack and remove the jack stands.
2. Test drive: Take your Mitsubishi Outlander for a test drive, paying close attention to the rear wheels. Listen for any unusual noises or vibrations. If everything seems fine, you’ve successfully replaced the rear wheel bearing.
