Do I need special tools to install this, or can I use what I already have?

You'll need a socket set, jack, and jack stands—standard stuff. The assembly bolts directly to the rear knuckle without pressing or machine work, so no specialty bearing tools required. Refer to your service manual for torque specs and the exact bolt pattern for your application.

What if the hub comes with corrosion or surface rust?

Light surface oxidation is normal on new bearings during shipping. A wire brush or light abrasive pad cleans it off in seconds before install. Don't use aggressive grinding—the bearing surfaces are precision-finished and need to stay clean.

Is the seal already installed, or do I need to add one?

The hub ships as a complete sealed assembly. Nothing additional is needed on the bearing side. Just bolt it on and you're done—the integrated seal is factory-installed.
