GM 14 bolt backlash ?

My 14 bolt has a whine over 30 mph while on the gas and cruising but it will stop when I let off the gas. I don't know the miles on the axle, it's from a CUCV. Can I adjust the backlash using a dial indicator and some marking compound to eliminate the whine, maybe move the carrier closer to the pinion, or are the gears done.
A local shop said the R&P need to be replaced because there is too much play in the pinion, I told him it had a Detroit locker in it, it should have play.
