SO you can install the locker from the back of the diff without messing with pinion bearing pre-load/etc.??? Sounds easier than I expected. Any special tools or pullers needed?
patience, rubber gloves, lots of bearing grease, and put the truck up high enough you can sit up under it if you can. The only special tool i use is a smaller screwdriver with last inch of it bent at about a 70 degree angle. The passenger side C clip is the fun part.
