I'm changing the rear wheel bearing on the right side of my 87S4. Do I need to order just the bearing or the locking & inner & outer wheel bearings?

The backs are single sealed bearings. Replacement is not as simple as the fronts. Several ways to do it. Here's one idea, following the WSM pretty closely.:

Porsche upgraded these bearings in the GTS and recommend retro fitting the newer type. They are expensive, big and the carrier must be heated to a specific temp before pressing them in/out.
If one needs changing, the do both.

When carrier is heated to correct temperature in oven bearing can be dropped out and in by hand as long as surfaces are clean. Using press to make sure new is in as far as it can go might be good idea but is usually unnecessary.
