8 3/4" sure-grip swap and rebuild questions

So everywhere I've read says that noisy gears will either stay noisy or get worse over time. I'm not sure how but after doing a few more short drives to break in the gears the noise has gotten noticeably quieter, particularly after I did a holeshot and WOT pull up to about 70 mph. It's still there for sure but it's not nearly as bad as the first time I drove the car after adjusting pinion depth and backlash and reinstalling the pumpkin this last time. I realized after searching and reading some older threads I didn't set the backlash in the best way so that might have been the issue, maybe I'll pull it and reset but it's gonna be a while until I'm feeling up to taking the pumpkin out again. Unless I can take it over to my buddy's giant garage with a lift and good lighting and heat lol.
