Ding-a-ling, just a word of caution, WD-40 is NOT a lubricant. The WD stands for Water Disperant. If has lots of solvents in it and will wash the oil from a joint. It may temporarly loosen a join by flushing some old lubricant into the joint.
Best thing to do is look for something that specifically states that it is a lubricant.
