If it leaks, it's bad....
Pull the plastic panel at the front of the car, and look around the rack. If you see fluid leaking, it's toast. If you don't see anything on the outside, loosen the boots that cover the piston, and pull them back from the rack itself to verify it's all dry.
Luckily, they're actually not that bad to change on these cars.

I suppose it's hypothetically possible to mechanically wear out a rack, but this just doesn't seem to happen anymore.....
If you feel slop in the steering, I'd check your tie rods first.

Let's approach this from another angle. What issues are you having that caused you to suspect the steering rack?
BTW, technically, there are no worm gears in a rack and pinion system.

issues
I am having the typical "bump" when traveling over bad road surface. i have replaced every control arm, trailing, tracking, wishbone, drop-link, tie-rod I&O balance tires,pressure, good rims, new tires. steering is great just trying to eliminate the rack as a devil. so. any recommendations on a shop in south part of NOR CAL?

I'm gonna share this as a noob to the world or Porsche...but I found the bump to be extremely surprising when I first drove the boxster. Then I found out that 8 degrees of caster will create amazing steering feel - and also significant kickback.
Don't know if it's normal or not.

I think Joefrompa may be describing what you're finding. Porsches have kickback.

Just an idea, but you may want to check the bearing on the top of the strut (spring) as well..
