I've noticed my freehub has gotten quite a bit louder over the last few months. Several people have recommended that I lubricate the freewheel by tipping the bike on its side and dripping lubricant into the freewheel. However, I've gotten differing opinions on what to use for a lubricant.
Is it safe to use a chain lube on the freehub or is there a better lubricant for this purpose?
Edit: In response to one of the answers, I have a freehub (2011 bicycle). Question edited appropriately.
