this repair is done from the inside,remove lower basket,screw off the center nut (its not to tight came off by hand, no tools)take off spray arm,take all the torque bolts out,remove the screen filter take the 3 bolts out of the pump housing and remove, mine came apart that was the noise. The impeller may not need to be replaced but mine had marks on it so I did.Install new seals clean up parts and put it back together with new parts ..works as good as new!!! I had my new parts in 1 (ONE)day PartSelect thank you. Andy,
