Wheel hub bearing question

[Blueridgerunner]

99 OBS Tahoe Z71. Looking online and a few of the replacement assemblies state "drilled mounting holes". I assume this refers to the 3 holes where it mounts to the steering knuckle. I would think that the mounting flange on the hub would have to be threaded because the bolts attach from the rear? Problem with ordering online.

I have a 99 as well. I ordered my via Fleabay for $50, from autoware or something like that. Never mentioned no mounting holes and THERE WAS NO PROBLEM with installation.
