The conveyor rollers used on the Aerocivic have bearings, but the ones on the car are a minimum of 10 years old. Installing a complete set of new bearings should reduce the clatter. McMaster-Carr now sells a corrosion resistant conveyor roller (2278T31) designed for wash down applications that is the same exact size as the ones currently installed on the Aerocivic and McMaster sells replacement bearings for them. The aluminum sheet on the front wheel well covers tends to amplify any noise generated by the rollers. I don’t mind some noise generated by the covers since it only produces it while making as sharp turn, such as at an intersection, and it alerts any gawking pedestrians to the fact that the car is making a turn. If you decide to use rollerblade wheels, you will need to have a string of them mounted side by side on a single axle since the edge of the tire covers a distance of 4” horizontally from the point where it first makes contact with the roller to where you reach the end stop on the steering.
