Rear Main Seal, OEM, 911 (996), Boxster (986), Cayman (987)

This is a first-quality brand-new (factory-sealed) wheel bearing for the Porsche Boxster. You need one per hub, or two per axle (driver side and passenger side). These wear out after 60,000 - 80,000 miles, and you will hear a noise during steady-state cornering.

These bearings aren't always available, so we will e-mail whether or not we have them in stock. You will need a bearing press (special Porsche tool) to remove/install these--we don't see how you could do this without the tool unless you take the hub to someone and have the bearing pressed out. Again, you need one per wheel, two per axle, or four per vehicle if you are replacing all of them.
