I had a wobble in my steering and after checking past blogs. I diagnosed the problem, bad control arm bushings!!!! So I went for a drive trying to make the steering wobble, it felt like it was getting worse. I decided to check out the problem. After lifting the car the driver’s side tire moved as if the steering had been turned. Upon inspection I find that there is now about ¾ of an inch play in the driver’s side steering rack, surprise!! I can now freely move the driver side tire left and right about 1 inch
I can’t believe I was driving the car. I assume the steering rack is now trash and it cannot be fixed. Are there any options in steering racks (performance racks??) that I should look at before replacement. Also are there solid (performance) tie rods available while I am replacing the rack

I understand that a bad rack will leak power steering fluid. Don't assume that the most expensive part is the problem, a common issue with Porsche owners. Old bushings that clamp the rack in place may be bad. or more likely inside or outside tie rods. As you move the wheel do you see anyplay in the inside or outside ball cup?

I vote for bad tie rods. not unusual with the age of these cars. changing the tie rods is not too hard - but you'll need an alignment afterwards,..

The tie rod is solid where it attaches to the wheel. I assume the other end of the tie rod attaches directly to the steering rack. Where it attaches to the steering rack it can now slide in and out about ¾ inch causing the driver’s side wheel to turn left and right about an inch (my wobble). It feels solid otherwise, when you pull it out it hits a stop. So if the tie rod attaches directly to the steering rack something in the steering rack is allowing the tie rod to move (only on the drivers side). I don’t see how it can be the tie rod??? Any ideas

Not always. I'd suggest getting under the car with the front wheels turned in the direction where you think the problem is. Unclamp the steering rack bellow and slide it to the side. Then grap the tie rod and move it in all directions with some force. This will allow you to see if the play is in your rack.
FWIW, I once had a BMW rack with up and down play in the rack and discovered it using this method.

the tie rod has 2 parts on these cars - and inner and outer part. there is one set per side. the two parts should not have any play between them. if you are seeing an inch of play where the innner and outer rod joins together - that is your problem. at least that way my experience....

It looks like the play is under the black cover around the tie rod. I did not know that they are two piece, it must be sliding where the two parts come together
Is there an upgrade for the tie rods that I should buy, per power steering cars upgrade to turbo tie rods is there anything like that for the 993

Has something been changed in this area of the car ? A bad reinstall of the tie rod thread into the steering rack end could lead to the thread damage.
