Do these mount at the factory rocker points, or will I need to drill?

These mount at factory points — no drilling or custom fabrication required. They bolt straight to your existing 4WD axle setup.

Will I need a press to install the bearings, or do they come already assembled?

They come fully assembled. You're installing a complete unit, not pressing races or wrestling with loose bearings. The bearing and seal work is already done.

What hardware comes with these, and what do I need to source myself?

The assemblies themselves ship without fasteners. Grab your factory hardware from the old hubs — spindle nuts, cotter pins, and dust caps are reusable. If you need a replacement spindle nut or hardware kit, run the part number with your local Ford dealer.
