    I forgot to record putting it back together 😢Putting it back together is pretty straight forward. If you have any questions be sure to drop them down below.

    Just so you know that collar where the pinion bearing is held in is reverse threads. And it is a bear to get out. My rear dif was in terrible shape and full of mud so it was hard to see how somethings came apart. There is only one seal that has me stumped. It’s the one below the needle bearings. I’m going to give it my best guess and hope it’s the right direction.

    I cut it off. If you cut almost all the way through then strike the cut you made with a chisel it will break. Then I ordered a new one from partzilla.

    If you have access to a welder just run a couple of small beads around the inside of the bearing race you want to remove (it's trashed anyway). As the beads of welding cool they will shrink and pull the race with it. You can usually knock the bearing out with little effort after that. I use this method on pressed-in car wheel bearings all the time and it works great. That way you won't cause damage trying to cut it out.

    The lat part is easy it is opposite thread spin right to unscrew left to tighten U can weld a bit of box section to it and use a pipe wrench had to do this because I tightened the crap out of it screwing it the wrong way hope this helps

    use a oven to get the bearing to fall out of the aluminum housings. Trust me it works

    The collar of the pinion gear has left handed threads. Lefty tighty, eighty looise. Use a 30mm castle socket.

    @@kyleryeager4941 yes I did. It's pretty difficult but what I did is get a punch and some liquid wrench and blow the soft punch into the gear from and angle. It comes out after that. Depends on your cenerio but after that removing the bearing is also difficult. Dry ice is also amazing
