Would love to say no, but when you are talking about a steel shaft under tension that can stretch, as well as a hub carrier end section that can peen over time from the shaft tension, not a bad idea to check the nut torque when you are at least changing the brakes.
Simply, the nut is loctite in place, was loaded to at least 140ft lbs, so at least set a torque wrench to 140ft lbs and see if the nut tighten's anymore before the wrench clicks.
If the nut does turn, then new nuts and loctite are in order, and make sure to the clean/lube the shaft and seating area's both sides (will require that you push the shaft sightly back in the hub so you can clean the back bearing areas of the two) before you install the new nuts with loctite.
To add, noise can be coming from the LSD instead, so if the problem is more of chatter of the LSD clutch clutch pads locking and unlocking, then the first step here is to replace the clutch pad dust contaminated diff fluid, to new clean fluid instead (Dextron LS Gear Oil 75W-90, part #88862624).
