I am literally about to pull my hair out.

I am rebuilding the rear diff for my brother in laws machine thus replacing all of the bearings.
I had to use a three jaw puller to get the old pinion gear bearing off the pinion. Long story short I have now purchased 4 differential aftermarket kits (some have been returned or refunded) including old faithful all balls (because everywhere online was back ordered ). All 4 of the bearings (yes they are the correct ones because they have the SCO4A90N on them like the OEM) slide right on to the pinion bearing–I do not have to press them on.

Does this matter? Am I the only one that has ever had this problem?Would y’all use them or should I just wait for the OEM back ordered ones?
