ok, stopped raining today so i had some time to check it out. is there supose to be a nut of some kind keeping that u-joint base connected to the rear? because theres nothing there, but i see the shaft is threaded.......lol. also, the part that came off got banged up pretty bad so im going to need to replace that as well. Its the part the rear most part of the u-joint is connected to. is there a part # for that or is it just part of the rear?
