My first idea was that it was something gunking up my bearings, but I cleaned them out and it still happens. Anyone have any idea what the problem might be? If it is something, is it a problem that could affect my ride? ….. only happens when I’m going straight. Any pressure on the rails at all and the noise stops. I bought some skate lubricant and I’m going to lube the pivot cup and see if it fixes it and if not I’ll try the bushings. Thanks for the responses, everyone! …
