I am refinishing a cart that has wooden wheels with roller bearing hubs.
I bought the cart new 24 years ago, since then I have never done anything to the hubs, never opened them up, never took the wheels off of the axel.
I put the cart up on the floor jack and checked the wheels, both turn very freely, are not warped as they turn and are not wobbly on the axel.
The right wheel, will free turn for 5 minutes, but it has a 3” metal piece sticking out of the hub, a piece like a lathe would make about the width of dental floss. I drove today and the metal piece did not get any longer.
Do you think I need to do anything to the hubs? Like open them up and regrease the bearings?
