It"s not that it's that hard but it takes some special tools.The pinion gear has to be shimmed , the gear backlash has to be set and the bearing preload has to be set.Also the bearing between the upper and lower halves has to be shimmed beings you would be putting on a different lower to your upper.This is better left to a reputable shop that is equipped to do TRS drives.Total would probably be at least $400 at a shop and they would probably try to sell you some bearings along with it.That's why I say you can usually get a complete drive for what it cost to set up a lower.
