The hub cleaning tool is designed to clean the hubs of most European cars and vans. It has a 1/2 drive socket which allows it to be used with the same tools used to remove the wheel, so no additional tools are required. The 7133 is equipped with a replaceable 160 mm diameter cleaning disc, making it ideal for most car hubs with a center diameter of up to 64 mm, and for cleaning the inside of both steel and aluminum wheels.
