Yeah your NEVER suppose to torque the pinion nut with an impact gun, ever. Sorry not to be a dick but I dont care how many people say you can do it or how many old school mechanics say its fine. Your suppose to use a cheater bar and set it to assembled rolling resistance with an inch pound old school torque wrench.

If its too tight you'll probably chew the bearings up quicker than you normally would.

And did you ever think that perhaps your other housing is tweaked/bent and causing the noise in the gears? Or maybe its an outer bearing?
