The function of the bearings in the drum of your washing machine is to help rotate the drum. Over time bearings can fail if water gets to them, should the bearing seal be damaged. If you notice crunching noises while the drum is spinning, it could be time to replace the bearings. With this replacement bearing, you could soon be back to a washing machine that sounds back to how it should, and perform to full working capability once again. Please check model fit list to ensure this part is correct for your model.
