handle in your ear for a stethescope.

If it comes from the spindle...pull the bearings AND MAKE A DRAWING of
it being disassembled (or take photos as you remove each part) and
order and install new bearings

As an old man who grew up in the shadow of The Great
Depression, I'd use solvent of some kind, and clean
out the old bearings. Regrease them, and see if that
helped. I do think the drawings and photos are
excellent idea.
