Question Focuser getting stuck

My 2", dual speed Crayford focuser is not rotating freely all the way, and gets 'stuck' (i.e. slightly harder to turn) at the same point during each turn - I have to provide additional force to turn it. Doesn't mater which speed I'm using. What could be causing this and how to fix it?
