Axle Rebuild Tools?

[liftedz71]

Im looking at a 14 bolt axle for my truck as of now and will rebuild, install new gears, and a tru-trac before i get itback in.....Iam aware of certain tools needed to set the backlash and the proper shim depth...where can these be found? I didnt see a write up but does anyone know a site that has step by step instructions for a gear or locker install? Any other opinions would be nice...
thanks\
