April 2019, Iron Rock Off-road 3” lift, 4.88 gears, 35” tires. All is smooth as butter until I dumped the clutch on dry pavement.

terrible noise in rear end, tried to take it to the dealer to fix it...

They wouldn’t touch it...(aftermarket parts)

took it to a local Jeep shop to have ARBs installed,told him the issue with the grinding noise, he has got it ~~~mostly~~~ resolved.
Said that’s all he can do because he shimmed the backlash all he had. (.008)

I still think that’s way too much according to ARB.
Should I just bite the bullitt & buy a case spreader & finally fix it myself?
I would have to buy a few other tools as well & more than likely a shim kit & a crush sleeve.
I just wanted someone to make it better but it sure doesn’t go down the road without annoying me.
Surely setting up a rear end can’t be that complicated if I don’t get in a hurry.?.
I could really use some advice.
It seems as though I cannot find anyone to repair my issue.

You have 4.88's with the LSD or with the locker? If they installed the locker, .008 is too much but that's not what's causing terrible noises you hear.

I'd take it apart and inspect your ring and pinion gears.
