Will I need a wheel bearing press to install this?

This is a cartridge-style assembly, not a loose bearing. You'll need basic hand tools and a socket set. If the old hub is severely stuck, a bearing puller can help; your local shop can press if needed, but many DIYers handle this with standard garage equipment.

Does this come with new lug nuts or retaining hardware?

The assembly itself is complete. You'll reuse your existing lug nuts and wheel fasteners. Check your service manual for proper torque specs on reassembly.

What happens if the bearing goes bad shortly after install?

Quality control is run on every unit before shipment. If you experience an immediate failure due to a manufacturing defect, contact ModSupply support with photos and install date—we make it right.
