Will this bolt directly to my Versa without modification?

Yes, this assembly is engineered as a direct replacement for non-ABS models. Test-fit before final torque to confirm alignment with your brake components and suspension geometry.

Do I need to replace the wheel studs or rotor at the same time?

Not required. This hub assembly is independent. If your studs or rotor are worn, address those separately based on your brake inspection findings.

What tools and hardware do I need to install this?

You'll need basic hand tools, a jack, and jack stands. Hardware for mounting and fastening isn't included — use the original hardware from your vehicle or refer to your service manual for torque specs and fastener requirements.
