Did you check with Moser before having the access holes drilled in the axle flange? This may throw off the balance of the axle if they weren't designed for them. The flanges on aftermarket axles are heavier than stock and will give a small vibration if not balanced.
The stock axles have three holes; one large access hole and two balance holes on the opposite side of the flange (like 12 o'clock for the bigger hole, and 5 and 7 o'clock for the smaller balance holes.) I had the machine shop duplicate that setup, so, hopefully, the balance should not be disturbed.
Which studs did you use? The axle should just be a threaded hole for the stud. Axles made for screw in studs take a special stud, they look just like a bolt, some race guys I know just use hardened 1/2" allen bolts.
Moser sent 11/16"-studs along with the axles, that fit the holes they had drilled and tapped; they worked perfectly after the shoulder was machined down so they'd bottom out correctly.
I do agree that they should have them cleaned up with no burring or sharp edges.
