Test Rods and Bearings?

I have a very old printer (CTC Dual) that's still running if very slowly and I wonder about the state of the rods and bearings.

The hotend has been upgraded and all other appropriate upgrades done except the bed platform.

Is there some reasonable way to check to see if any of the mechanical bits should be replaced?

I have the feeling that the poor old thing might be nearly beyond its economic life.

Take the belts off, move the linear bits around by hand. If they move smoothly and quietly, and don't wobble, they're fine.
