I am going to do that just hate messing with the pinion preload.

 

Found a page on Spicer website to look up the u joint size with the BOM number and the rear axle was switched. Because the window sticker says it has a hybrid 80 (Dodge called 70UHD) disc when I clearly have a 60 drum plus the driveshaft says 318 Auto so I'm assuming these parts came from a junkyard. Oh and my rear driveshaft has a tiny rust hole in it

 

That would explain a lot....

 

I guess you expect that because I get them so cheap lol they tried to pair a NV3500 to a diesel . Still going to post a video tomorrow for you guys
