Wheel Bearing
Typical layout and location for the Wheel Bearing assembly.
Symptoms
- Humming, droning, or roaring noise from the wheels that increases with road speed
- Noise changes pitch or disappears when turning slightly left or right
- Slight vibration felt through the steering wheel at motorway speeds
Root Cause
The sealed bearing unit loses its grease over time, or water ingress causes the steel balls/rollers to pit and rust. Impact damage from potholes can also cause a flat spot on the bearing race.
How To Fix
- Jack the car up and check for play by rocking the wheel at the 12 and 6 o'clock positions.
- Spin the wheel and listen for a rough rumbling sound.
- Press out the old bearing and press in a new OEM-quality bearing (e.g. SKF, FAG, SNR).
- Cost: £120-250 per corner

Other Faults on This Variant
Exhaust Back Box Corrosion
MinorThe mild steel exhaust back box rots through exceptionally quickly, often causing the exhaust to snap and drag on the floor.
Body Control Module (BCM) / Wiring Loom Failure (Hatch Wiring)
ModerateElectrical gremlins are common on the Fiat 500. The most notorious is the wiring loom snapping where it passes from the body into the boot lid/hatch.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
