Rear axle seal radial play

Folks, 93 K1500: both rear axle seals are leaking, and one of them is leaking after I installed it new a couple months ago. I’m concerned the axle shaft bearings may be worn? Truck has 290,000 miles. Radial play on both is about 0.010” according to my dial indicator. Is this excessive?

I also checked that the vent was not clogged just in case that was a factor.
