Hi Daly,

I'm doing great.  Unfortunately, I have to admit I'm not that familiar with the rack and pinion.  I know the concept but I've actually never owned a car with that set-up.  There is a fairly universal approach to the adjustment you want to make:

The manufacturers detail how much 'torque" is required to move the steering wheel out of its centered range.  The Porsche manual may have that.  As you make the adjustment you can pretty much adjust, and adjust some more, til you get the feel where you want it.  The idea is that to completely reduce any play at the centered position, it will require more effort to move it from that position.  Easier steering means more play.  So...you will want to find a happy balance.

As for the knocking in your front end, here's what I'd suggest.  Jack up the front end and get a good light to see what you're doing.  Use a very large pry bar to try to dislodge suspension points.  If you can move an a-arm it means the bushing is bad and that is causing the sound.  If you can move anything at all with a pry bar, that is too much movement.  Every suspension joint (especially rubber bushings) has to be tight or it needs repair.

Have fun with it...but don't break anything with those huge muscles of yours.
