What type of noise?
It only does it during the wash cycle when the agitator is moving back and forth.
Watch it while it is in wash mode and see if the tub is going from side to side or wobbling. If it is, raise the top and look in the corners for rubber dampers going from the tub to the washer itself. One or more may be broken if it has them. If it has springs on the bottom that serve basically the same purpose, check them. These will be heavy springs if it has them. Be careful when installing or remmoving. Do you know if it is direct drive or belt driven? If direct drive, definitely check the coupler. Not really sure how far back the direct drives go. Just some suggestions without being there to actually see it.
