Sort of - it's best to set it in the car. I normally build diff up and tighten it until it holds together, then put it in the car. Hold one wheel in one hand with your index finger holding the spur so it can't move and try and turn the other wheel. If it moves, tighten the diff slightly (1/8th a turn or less) and repeat until you cant make it slip. I then run my diff in by holding one wheel so it can't turn and running the car at half throttle for 30 seconds, then recheck the tightness.
Another thing I've noticed is that now I'm using thicker diff oil my diff feels a lot tighter than it used to, even though it's actually pretty loose
