tighten my ball screws

My old CNC mill, Excello - bridgeport type, needs some attention to reducing
backlash in the ball screws. What can be done to reduce backlash, short of
replacing them?

I'm tempted to try taking apart the ball assembly and cleaning and
tightening. Will the whole thing fall apart,leaving me with a pile of ball
bearings?

Or, are there places to send ball screws out for rebuild?
