Wow, Matt! That's a good site. I'm definitely bookmarking it. A wealth of info! Thanks & welcome to MUD!Toyota Gear Installs should be very helpful if you don't find the install manual. You're just putting the bearings on the Detroit then replacining the carrier (in which the spider gears are located) with the Detroit carrier and resetting the gear backlash. The only less common tools you'll need is a dial indicator and a press.
