So, I know a couple of people have had the problem of turning the steering wheel to the left or right, and having it not return to center until they turn the opposite direction. For me, it was turning to the right, the steering wheel would only come back to about 2 o'clock, until i would make a left turn, of which it would return back to center (12 o'clock). I have had the problem for about 2 years now, and just haven't had the time to deal with figuring out what it was (same issue after new tie rod assemblies, alignments, new suspension, control arms, steering shaft, new PS rack etc). I also had a shaking in the steering wheel when traveling at interstate speeds, bad between 60-70mph, once over 75, it would more or less go away. So, I decided that I would just drive a bit faster

So I started thinking about it, and the only thing I could come up with was: With the rebuilt rack, there was some play in the rack up and down if you grabbed the ends and pushed and pull. If this was the case, I would go to a manual rack and be done with PS. The other thing was the 2 rubber steering rack bushings for the mounts.

So I bought some mounts about 6 months ago, and today finally got around to putting in the 2 $10 rubber mounts that have been sitting on my box for way too long. The old mounts fell apart when I took them off. Got the new mounts in and...well....steering now returns to center, and the vibration is gone. Took all of about 15 minutes to change them out (undo 2 13mm bolts on each mount, and I also took the 2 13mm bolts holding each sway bar drop link to the frame, just for a little extra wiggle room).

Cliff Notes:
1. If you turn the wheel, and if it doesn't return to center until you turn the wheel the opposite direction, replace your rack mount bushings.

2. I am an idiot for not doing this 2 years ago.

Now I can get on to my next project......

More notes....

3. Only the left hand steering rack rubber bushing has raised shoulders that hold the steering rack in place laterally.

4. Paragon sells a delrin replacement for the left side rack bushing for more positive positioning and feel.

5. You are an idiot for not doing this 2 years ago....

It amazing how we will put up these things. My steering was ****TY for a few months until I did this quick and cheap little job. Bingo perfect steering!

Caster issues possibly?

LOL, that always bugged me to death back when I had the car. I am glad you have finally figured it out. Like you said numerous people have had this problem including my dad's 951.

Holy cow, you just described my car. I keep trying to center the steering wheel and I can never get it quite right. And its at exactly the same speed that it vibrates. I thought it was my control arms, which are in need of refurb.

Now the question is OEM or Delrin.

PorscheDoc

Uh, crawl under the car, and there it is.


And holy old thread batman......

Which mounts are these? I think I might have this problem

V2Rocket

my problem with the wheel off-center stemmed from the fact i reinstalled the wheel wrong lol

PorscheDoc

Is the actual mounting points of the rack. Under the U brackets that hold the rack to the crossmember are rubber bushings.

I have replaced all the rubber in my front suspension, forgot about the steering rubber bushing so I though I order up a set. Got a little sticker shock, $160 for the set. Ouch!!

Same issue here, replaced the driver's side with the Paragon delrin bushing since it's the one with the shoulders that actually locate the rack and just replaced the other side with the stock rubber bushing.

Centering problem solved and the steering felt sharper afterwards.

Greg -- i recently did the same steering wheel set up as you have on my 968 -- only I got the carbon fiber wheel like what comes stock with the Carrera GT and the leatherette bag [all in black/on my black interior]...

Your 944/968 interior is the nicest one I have ever seen.

At the last moment I remembered to center the front wheels and I got lucky using a used clockspring from a 911 turbo that was also properly lined up. [my carbon wheel was originally manufactured with less internal structure to work with for cutting]... what I mean to say is that I was only safely able to bore the inside of the wheel hub about 1/8 inch... the conical-shaped hub did not have the clearance to bore any deeper at that boring diameter... so, I simply cut off the back of the wheel hub 1/4 inch. This netted 3/8 inches... and I was able get the wheel safely on... I did an extra careful job grounding my extra wire as to try to minimize any possibility of the airbag light coming on...

btw, do you know how many of us 944/968 drivers are running 996 three-spoke wheels ?
