<DIV>If they are real sloppy, then I would replace them. However, if there
is a very small amount of play up and down (1/64" or less) then you can usually
get rid of the slop by simply tightening the 4/40 bolt while holding the
aircraft nut on the bottom. But, like I said, only if there is a very small
amount of play.</DIV>
