That question came up when we were having U joint problems. A call to the differential manufacturer produced their specs on end play. There has to be some end play. We ended up within the specs and did not remove the pinion for inspection. I still maintain that there is cause to suspect the U joints. At least remove and inspect before the next more expensive option. In our case, ride height was the cause. Chuck B

Phil, I'm w/Fred on this. Diagnosis on a tapered bearing w/out
pulling it is tough unless the thing has seized & spun so that you can
see outward signs of the damage.
And IF it is the bearing, there is a cause. Mere end play of the
assembly doesn't mean bearing for sure and exclusively. IF bearing is
bad, cause could be incorrect installation initially, could be
inadequate lube, could be overstress from some outa balance part like
drive shaft or u-joints. IIWM, I'd get new U-joints while in this
process regardless, and have the driveline checked for balance while
its out of the rig. Those won't cost a lot, and after opening the
rear end, it would be nice to go home feeling like the problem was
truly solved. Mike
