Fiat Idea Wheel Hubs Available Here. One of the most important parts of your car is the wheel hub assembly. Wheel hubs are located between the brake drums or disc and the drive axle. These hubs take on the load of the vehicle whether it is in motion or not. While these hubs can take a beating, they don’t last forever. One of the telltale signs to check your wheel hubs is if you hear chirping, squealing, or grinding sounds at different speeds. At MicksGarage.com, we offer thousands of wheel hub products to make replacement a complete breeze. No matter the type of wheel hub assembly your car uses, our high-quality hubs will get your car back to ship shape in no time.
