Step 1: Gather Necessary Tools and Materials

Before you start, make sure you have the following tools and materials on hand:

• Socket set (including deep sockets)
• Wrench set
• Torque wrench
• Hammer
• Prying tool or flathead screwdriver
• New rear wheel bearings/hub assemblies
• Brake cleaner
• Lubricant
• Safety gear (gloves, goggles)

Step 2: Lift the Vehicle

To begin the replacement process:

1. Park the Fiat 500 on a flat, stable surface.
2. Engage the parking brake for safety.
3. Use a jack to lift the rear of the vehicle.
4. Secure the vehicle with jack stands to prevent any accidents.

Step 3: Remove the Wheel

Once the vehicle is elevated:

1. Use a lug wrench to loosen the lug nuts on the rear wheel.
2. Remove the lug nuts completely and take off the wheel to access the hub assembly.

Step 4: Remove the Brake Assembly (if necessary)

Depending on your model, you may need to remove the brake assembly:

1. Locate the brake caliper and use a socket to unbolt it.
2. Hang the caliper using a bungee cord or similar tool to avoid stress on the brake line.
3. Remove the brake rotor by unbolting it if needed.

Step 5: Remove the Old Hub Assembly

To access the hub assembly:

1. Identify the bolts securing the hub assembly.
2. If the bolts are rusted, spray them with penetrating oil and allow it to sit for a few minutes.
3. Use a socket to remove the bolts. A hammer may be required to tap them loose if they are stuck.
4. Once the bolts are removed, gently pull the hub assembly out of the axle.

Step 6: Install the New Hub Assembly

To install the new hub assembly:

1. Align the new hub assembly with the axle and push it into place.
2. Secure it with the bolts you removed earlier, tightening them to the manufacturer’s specifications using a torque wrench.

Step 7: Reassemble the Brake Assembly

If you removed the brake assembly:

1. Reinstall the brake rotor and caliper, securing them with the appropriate bolts.
2. Double-check that everything is tightly secured.

Step 8: Reattach the Wheel

To finish up:

1. Place the wheel back on the hub and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and then fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
