Using your Wildkart front aluminum wheel hub is easy. First, make sure the spindle shaft is 25mm in size, as this hub is specifically designed for it. Install the wheel hub onto the shaft and attach the wheel using the 8mm wheel studs. You can also use the removable aluminum wheel centering register to ensure proper alignment. When it comes to maintenance, regularly check the bearings. Since they are recessed 40mm into the hub from the outer end and spaced 55mm apart, they need to be in good condition for optimal performance. If you notice any unusual noise or difficulty in turning the wheel, it might be time to inspect the bearings. Keep the hub clean to prevent dirt and debris from causing damage. Always follow safety guidelines when working on your vehicle.
