Do I need any special tools or hardware to install this?

You'll need basic hand tools and a wrench set to remove the old hub and secure the new one. Mounting method matches factory points—no drilling or custom fabrication. Check your service manual for the correct torque spec on the axle nut and mounting bolts.

Will this fix wheel wobble and ABS noise?

A worn hub and bearing is usually the culprit. If you're getting play at the wheel rim or ABS codes, this assembly addresses both. If the problem is something else—like suspension—that won't change, but a bad bearing always needs replacement.

Is this assembly sealed against water and road salt?

Yes—the bearing is pre-sealed and lubricated. That said, inspect the rubber seal during install; if it's damaged in handling, you may want to repack it before mounting. Normal road use won't compromise it otherwise.
