Do I need to repack or service the bearings after installation?

No. These come as sealed cartridge units—no repacking or maintenance needed. Install and drive.

What fasteners do I need to bolt this on?

The assembly uses factory bolt holes. You'll need the original hardware from your vehicle, or grab a new bolt set from your local hardware store if yours are worn or stripped.

Can I install this myself, or do I need a shop?

If you can remove the wheel, brake components, and disconnect the axle or suspension arm, you can do this. A jack, basic sockets, and a breaker bar are all you need. Refer to your vehicle service manual for torque specs and the exact removal sequence for your position.
