I had made two purchases. The first was a custom axle which was very good. The second was this purchase of two 5x5 hubs. The hubs did not measure as stated.Instead of 5x5, they measured 5x4.75. A very lengthy discussion ensued with customer service. When asked for pictures, I sent pictures. Measurements and diagrams were also sent when requested. The service rep then started asking for what I had already sent indicated that I couldn't be helped unless I re-submitted all data again. I stated what I received was a manufacturing mistake and simply would not fit. The company couldn't send me the correct hubs. Very frustrated, I asked for a return label. I was informed that I would be billed for your mistake and pay to ship back the defective merchandise. No stars less than one.
