Posted: Tue Nov 24, 2009 4:41 am Post subject: Steering Rack Interchange?
This is pretty much directed at ZSPOT, but I'm open for all ideas and input.
I think I'm going to be replacing my steering rack this coming spring/summer. It has 160K on it and the seals are shot (and have been for a long time) - it leaks internally and I'm getting some front end squeaks over bumps and such that still exist after replacing every part in the suspension. I haven't been able to get underneath the car recently, but I now have a new slight looseness in the front end that I am definitely attributing to the steering.
I am leaning strongly towards getting a rack from Nordstrom's as they can be had for $150 and they typically have less than a hundred miles on them. I have the 7B3 suspension right now on my 9C1, and I want to say that the racks are all the same throughout the 2000-2009 years, but it's hard to determine for sure...
FE1 appears to be it's own rack (soft ride suspension) throughout the years.
FE2/FE3//FE4/7B3 appears to be the same rack throughout the years, with a tighter gear ratio than the FE1 rack. It also appears that the 06+ 3.5L (assuming LS model) has the better rack, where as the base model for 00-05 had the FE1 rack...?
Of course, I want to make sure that all the racks throughout the years are interchangeable as well (at least within the FE2/FE3/7B3, as I really don't give a crap about the FE1 soft rack).
From looking at Rockauto and AC Delco, it appears that they sell only remanufactured racks, which makes it hard to determine with 100% certainty what the right rack would be. Ideas? Thoughts? TIA!

I installed a used oe fe2 rack with 14k miles and the steering feels much quicker and precise. fe4 is from the ss frm what information I have been able to gather. Other than that, i haven't been able to find much
AFAIK the racks have different bodies between the 3400 models and 3800 models where the fluid lines go in. On the 3400, they go in from the side, on the 3800 they are angled towards the RF corner. Barring that, they should otherwise be the same on the outside, the differences being the inner gear sizes. IIRC the SS has a different track width than the other models so its turning radius was different, but that may also be from the tires or spring heights.
My laptop crashed and I havent restored my car files and photos, I'll check my junkyard pics later and confirm the P/S fluid lines difference.
