How easy is it to install 3.73 gears?

Now the crush sleeve just creates some backward pressure on the pinion while the pinion nut creates forward pressure, right? So if I get the pinion nut to the exact same tightness as it originally was, the crush sleeve should be doing it's job. Here was my mentality: if I do it wrong, I drop the rear end and have someone fix it. By the way, I dont own any air tools, so I have to work with mallets and breaker bars and crushing a crush sleeve sounded like it was out of the arm power range of this lowly programmer =P. But it worked (i.e., I got lucky). Even on engine braking at highway speeds, the gear doesnt make a peep. The driveshaft is ready to shatter and fly out of the car but thats a different issue. Hey if it all blows up.......4.30's!!!
