It sounds like excessive backlash in the ring and pinion to me instead the Detroit locker. The Detroit will make quite a sound if there is excessive backlash when it locks in.

New R&P, when i felt the driveshaft slop of 1/3 of a turn i thought the same thing. Damn! I blew the backlash adj. Pulled out the indicator and checked. .008
? ? ? The 1/3 driveshaft turn was before it started to turn the R&P
Then i saw that it's common on the Eaton faq page

I am guessing the slop has to be between the axle splines and the Detroit carrier then.
If you're really worried about it, Sell that one and put the new one with SL in the part number.
Problem solved.

Being a 30+ yr Journeyman Toolmaker, i sometimes find myself not being able to stop trying to figure out how things work/tick
Constantly have to remind myself

I agree, just send it.
While having a locker has it's tradeoffs on the street, once you get it in the dirt it's like magic.
Add a front Locker and you'll feel like you're driving a tank, almost unstoppable.

Drove mine in the snow storm in February. No issues with going around corners or anything even on snow covered ice. It was a lot of fun being able to just whack the throttle while going straight and have the rear end walk out and drift as long as I wanted.

As long as I am easy on the throttle no issues with the Detroit and I coast thru corners, It does lock and unlock at times but not excessively harsh or noisy. But having a general lack of horsepower and 4.10 gears make it less obvious, I am sure if I had more horses and/or lower gears it might make more noise and lock up more. Been running it for 15 years with zero issues.
For the record, you can see where the slop in a Detroit comes from. Zoom in on the center of this locker, the gaps between the square teeth on the axle gears and body are cause (not the r&p or splines). It’s inherent to the design.
By now it’s a moot point but… run it.

Yes, there has to be some pre-determened clearance between the square cut teeth so that the locker can lock and un-lock to differentiate, or it would never unlock.
I know this but the subject was about the yoke slop and that is the main source.
Yes and turning the yoke till the r&p play PLUS the detroit play AND the axle shaft play in the side gears all get tight 1 direction or the other will give your input yoke a LOT of play over other units / designs .
I sure like my arb’s 
NO! its about the angle of the dangle.
