ill install it for you for $150, you just need to set the backlash back. you will need, a dial indicator, a spanner tool to adjust the adjusting nuts on the side to set backlash, might need a press, if your going to save the bearings on the carrier youll need a good puller. readjusting the pinion depth should not be neccesarry with a carier change as long as your pattern was good to begin with, if it a factory gear setup then im sure it is fine. and youll need your basic tools to get the third out and the ring gear off the carrier. if you need anything just give me a shout.
