Is there a removal, and installation guide for this? I looked on shbox.com but didn't find anything

 

Jack it up, take the Tires off. Take the Pan off and drain it. Then take the Brake Calipers off of the Axle so it can slide out. Then look into the Rearend for the bolt that holds the Pin for the Center Spider Gears. Take out that Bolt and slide the Pin until the Axles can come into that center area. When you do this, you will see a C Clip on each Axle. Remove these Clips and slide the Axle out about a foot. Then unbolt the 4 bolts on the Rear Caps, and remove the Carrier with the Bearings. There may be Shims/Spacers on the sides of these. Then take the Nut out of the Yoke on the Drive Gear, remove the Yoke, and pop it out of the Pumpkin. There will be shims here also.
To install, pretty much the reverse, I am not the best with those shims. You ned to set the Ring Gear and the Drive Gear to each other, so they will need shims on them.
