Doesn’t WD-40 just remove water and then it leaves behind some lube?

If you want ‘less response’ at the cost of a shorter bearing life and more noise, clean the bearing with solvents like mineral spirits and don’t add anything back to it. Most people find that a few drops of oil is well worth the tradeoff.
