whirpool duet model # wfw9750ww01

Our bearing has went bad. from what I have read, it appears we need to replace the whole outer tub??? Is this the only bearing on the washer? Is there no way to just replace the bearing and seal or do you have to replace the whole tub??? When I went to whirlpool website the picture for the outer tub did not resembe what I need to replace and there 2 different items listed as outer tub, so which one do I need???
