skateboard one wheel
One of my skateboard wheels become slow, but the other 3 are just fine. What do I do?

When I put in the bearings in that one slow wheel it’s not as fast, but if I put that exact set of bearings on a different wheel it works just fine. How should I fix this? [The slow wheel and the other 3 wheels are the same. They are Almost wheels 52mm with Element Thriftwood bearings.]

change the slow wheel to a different axle (switch sides: slow with fast)
then if slow wheel is still slow, bye some spitfire wheels

if the fast wheel becomes slow, buy one new truck (same size)

if can’t tell, buy some bones reds bearings
