First time rebuilder - struggling with steering rack

[Jem]

I thought hit me - It's not something stupid like the suspension is in full droop as it's just been built and there's no weight from engine/body/wheels and I haven't set any geometry because of no weight?

With the car on it's wheels and weight on the suspension, the steering arms would raise from their current position and the distance between them would widen, wouldn't it? don't know if that would be enough, but if the rack and track rod ends are OK, there must be another reason...

if the bump steer is adequately minimized there should not be any significant change in toe in/out when the suspension in compression or droop. Fwiw I had measured the distance tie rod to tie rod on my s4se (almost in straight line...) and it was 104.25cm

Bucklands book has 42.2" (107.2cm) tie rod center to center. This was close to my measured dimension.

Hi Jem,
I see this subject is a few years old but did you get to the bottom of this issue.
I have taken on a rebuild of a 69 fhc and have the very same problem as describe.

Any wise words?

Not an answer to the question, but when you do the job don't forget the rack needs the right thickness shims when fitting.

Hi
I had a similar problem on my rack. I traced the fault to my track rod ends not tapped deep enough as much as 3/8
luckily the track rod was drilled enough for me to tap it deeper
might be worth a check

I'll measure it today and post details tonight.

thanks

Jem, sorry to mention if you've got it taped, but don't neglect the shims under the rack.
