Quick background info - If you have seen my previous question I have switched my skateboard wheels to longboard wheels. I have "REDS" bearings in the longboard wheels, in they fit quite nicely with the risers I am also using now. On each side of my longboard wheel I have a washer, one on both sides of each wheel. Yet they shake left to right very easily. Wondering how I can tighten it up a bit? I do have excess washers, I thought about adding more but was wondering if it would affect performance. Open to suggestions, thanks! Easy 10pts for whoever solves this problem.
I don't think you should put in more washers, but have you tried simply tightening the axle nut more? That is the normal way to fix your issue. I don't know how else you would solve that..
