I ordered the parts from parts select and was pleasantly suprised at the diagnostic diagrams, the home install video, and the quality and pricing of the parts. I had ordered just the top bearing a few years ago and did not realized the bottom seal was bad also. I found the seal pushed down around the pump housing which caused excessive ware on the pump housing top and the top of the wash arm because the gap in the lower seal expanded over 1/4 inch causing the wear on the top of the wash are. This job is normally very easy. Unscrew the thumb screw on top, remove old bearing, pull off the wash arm, remove old seal. Then just put new seal on top of pump (check for any burrs and remove with a fine grit emory sand paper) put on the wash arm, insert top bearing and tighten finger nut tight. I had excessive wear (due to age of unit and lower seal not in proper position), so I had to construct a spacer to take up some of the slack. I could not find a nylon washer(and you need nylon) in the stores ready made and did not want rubber or metal washers due to the adverse effects these would have on the new bearing. I improvised. I purchased a pack of 10 nylon wall anchor washers from Menards (after they said no nylon washers were available:) I used 2 inch O.D. washers with 1/4 inch I.D. which was a perfect center hole and used a drill to enlarge center from 1/4 inch to 1 inch I.D. (to fit around the finger nut screw stem), and removed all burrs. Unscrewed top finger nut and placed under nut on top of seal and the 1/8 inch width took up the slack. Problem solved.
