Steering rack position

This may be an elementary (stupid) question, but here goes...

I have disassembled my steering rack and I am in the process of rebuilding and reassembling it.

When the rack is set in place and the pinion reinstalled, is it necessary to bias the rack away from driver's side of the car or will the rack simply turn from tie rod to tie rod and then once the tie rod ends are connected to the struts, this will create the correct bias and then the attachment can be made at the steering column?

I just dont want to have to learn the hard way and have to disassemble.

If it does have to be biased, I obviously did not measure this prior to removing the pinion, does anyone have this measurement?

No need to bias it. The rack is positioned in the car centered. You can confirm this by noticing that the tie rods are the same- there's no left or right rod.

When it comes time to connect your tie rods, you want to set the rack so you have the same number of steering wheel turns lock-to-lock and of course you want your steering wheel "clocked" correctly. You can correct the steering wheel clocking by pulling it off the shaft and rotating it a spline or two and you also can fine tune the steering wheel clocking by adjusting both tie rods by the same number of turns.

I thought that was the case but in reading through the rebuild procedure in one of the Porsche tech articles it mentioned marking the length position of the rack before removing the pinion and I was trying to make sense of that.

Also. My prior tie rod ends were off set quite a bit differently from one another. I marked those measurements. Should I keep those the same when reinstalling or should I make them even.

My plan was to install and then take to have aligned so I know this will only be temporary but it needs to be close to drive to shop.

If the rack is perfectly centered in the car, why would the measurements for the tie rod ends be different by more than a cm from the previous alignment?

Well generally speaking the rack is centered in the car and that's why the tie rods are same left or right. Of course the best thing to do is make the lengths of your replacement rods the same as the old ones. That will get you close enough to get the car to the shop.
