The Fiat 500, with its charming design and nimble handling, is a popular choice for city dwellers and commuters alike. However, like any car, it’s prone to wear and tear, and one common issue is a worn-out rear wheel bearing.

This guide will walk you through the process of how to change rear wheel bearing Fiat 500, empowering you to tackle this repair yourself and save some money.
Gather Your Tools and Supplies
Before you begin, ensure you have the following tools and supplies:
- Jack and jack stands: The jack will lift the car, and the jack stands will safely support it while you work.
- Wheel wrench: This will be used to remove the wheel.
- Torque wrench: This is essential for tightening the lug nuts to the correct specification.
- Hammer and punch: These will be used to remove the bearing race.
- Bearing puller: This specialized tool will help remove the old bearing.
- New rear wheel bearing: Ensure you purchase the correct bearing for your Fiat 500 model year.
- Grease: Use a high-quality bearing grease to lubricate the new bearing.
- Cleaning supplies: You’ll need rags, brake cleaner, and a shop vacuum to clean the area before and after the repair.
- Safety glasses and gloves: Protect your eyes and hands from debris and potential hazards.
Preparation: Safety First
Before you start, park your Fiat 500 on a level surface and engage the parking brake. Ensure the car is in “Park” if it’s an automatic transmission. Chock the front wheels to prevent the car from rolling. Now, it’s time to lift the car using the jack and secure it with the jack stands. Remember, safety is paramount, so always take precautions and ensure the car is securely supported before working underneath it.
Removing the Wheel and Brake Components
With the car safely lifted, you can now remove the rear wheel. Use the wheel wrench to loosen the lug nuts, then remove the wheel entirely. Next, you’ll need to remove the brake caliper and rotor assembly. Start by loosening the caliper mounting bolts, then gently pry the caliper away from the rotor. Be careful not to damage the brake lines. Once the caliper is removed, you can remove the rotor by gently tapping it off the hub.
Accessing the Rear Wheel Bearing
Now you have access to the rear wheel bearing. Before you remove it, inspect the hub and surrounding components for any signs of damage or wear. If you notice any rust or corrosion, it’s a good idea to clean it thoroughly using a wire brush and brake cleaner.
Removing the Old Bearing
The next step is to remove the old bearing. You’ll need a bearing puller for this. Position the puller on the bearing race and carefully tighten it until the bearing is removed. Be careful not to damage the hub while using the puller.
Installing the New Bearing
With the old bearing removed, you can now install the new one. Apply a generous amount of grease to the new bearing and seat it securely onto the hub. Ensure the bearing is properly seated and that there is no play or movement.
Reassembling the Components
Now, it’s time to reassemble the components in reverse order. First, replace the rotor, ensuring it’s properly seated on the hub. Then, reinstall the brake caliper, ensuring the caliper mounting bolts are tightened to the correct torque specification. Finally, replace the wheel and tighten the lug nuts to the correct torque specification.
Final Steps: Lower the Car and Test Drive
With the wheel and brake components reassembled, lower the car from the jack stands. Double-check that the car is safely on the ground before removing the jack. Take your Fiat 500 for a test drive to ensure the new bearing is working correctly. Listen for any noises or unusual vibrations. If everything seems fine, you’ve successfully replaced the rear wheel bearing!
