I had to replace the tub bearing, bearing ball, seal, the spider arm because it was broke in 3 places and the shock absorbers 2 of them were bad. Since I had the washer torn down that far, I replaced the seal between the tub halves. It took roughly 6hrs to take it apart and put it back together, about an hour to clean up the tub and misc. parts. The hardest part was getting the bearings out of the tub, definitely use WD40 or something along that line, when resetting the bearings in the tub there is a tool specially made for reseating the bearings. If you can borrow one or rent one definitely get one, makes the job a lot easier. Also Appliance Parts Pros has a GREAT video that will take you step-by-step through the whole entire project.
