I am wondering this as I have been driving my car this week with the great weather and fall temps here in SC, and I have noticed something that just doesn't feel right, and I am not sure I can put my finger on it, or even describe what I am feeling but I feel like my steering should be super tight, since a few years ago we did all the bushings bearings turbo tie rods ball joints brakes etc etc, everything but the steering rack itself and I didn't replace the front strut inserts because the feel fine.
wheels are 16'x6" 205/55 Potenza AE11's. 4 years old about 5,000 miles of use, lots of good rubber on there yet, but regardless will have to replace in another year just due to age of the rubber... so with that, here is what I think it feels like, kind of like it wants to jump around or shift off track. no vibration , no rattle , and I can grab the tire/wheel with car parked and try to move it back and forth and don't feel any play like if you had a loose or work tie rod or ball joint etc., what I guess I am wondering is if it is time to pull the steering rack and replace it with a rebuilt one from 914rubber. if that hockey puck thing is getting old and worn, what would that feel like or how would that present itself? And can I remove it by just disconnecting the inner tie rod ends and not have to mess with my alignment? ive not done a steering rack on a 914 before.. as always , advice from those that have done this is appreciated.

You can also do some reverse engineering and math w.r.t wheel offsets that may have increased your scrub radius.
If you know the offset of your old 4 lug 14" wheels and the offset of the new 16" + spacer, find the difference. You then have an idea of how much change you're fighting. I suspect it may be more than just the 1/2" spacer you added. Bottom line, you could look for a new 16" wheel with more offset that would put the center of the tire contact patch back where it was at with the 14" wheel/tire combo. Keep in mind scrub radius and bump steer are different things but too much of either will make things squirrelly. |

I can't imagine 6x16 Fuchs would give you a problem but anytime you have a front suspension issue, it's worth throwing on a different set of wheels. If it makes a difference, you've usually narrowed down your problem quickly. |
