Will this bolt directly onto my truck without modification?

Yes. The 6-stud pattern matches your OEM setup—no drilling, reaming, or adapters. Push the assembly onto the axle shaft, align the studs, and bolt it down using your factory lug nuts.

Do I need new hardware or fasteners to install this?

You'll reuse your existing lug nuts and axle shaft. If any bolts or retaining hardware look corroded or damaged during removal, replace them—your service manual lists part numbers.

Is the bearing greased and ready to go, or does it need prep?

The bearing comes sealed and pre-assembled. No additional greasing, packing, or field maintenance is required before installation—install it and move on.
