Do I need any additional hardware or fasteners to install this?

The hub assembly itself is the sealed unit. Check your vehicle's service manual for torque specs on the mounting bolts — you'll need the correct fasteners for your specific model, but they're standard hardware you likely already have or can grab locally.

Can I reuse the wheel speed sensor from my old hub?

Sensor compatibility depends on your model year and configuration. Test-fit before committing to reuse — if there's any doubt, ordering a new sensor with the assembly eliminates variables on install day.

What's the return window if something doesn't fit?

Test-fit immediately upon arrival so you know before you pull the wheel off. Document fitment issues with photos and reach out to support with your order number — they'll work with you on the next step.
