That's what the word "tolerance" means.
You have a "low" carrier, and a "high" crownwheel.
In a perfect world, a 1/2 thou, would give a nice transition fit, almost clearance fit.
Your current combo with a smear of 140w
oil, nip up the bolts, fit the hemisphere only, measure gear runout, get a happy zero, remove the hemisphere, torque up all the bolts, fit the pinion, check the crownwheel pattern etc.
