I thought I would share what happened to me so that in the future, or now, someone else could benefit.
Last year I replaced my steering wheel with a wooden one. Everything was find but I soon saw that when driving straight, the steering wheel was crooked.
I finally got fed up at looking at it and decided to get it fixed.
I went to my friendly neighbourhood Alfa mechanic to "straighten" the steering wheel out.
Mine is an S4 so the steering wheel column is splined, so no big deal, we move it over one tooth.
We went to remove the wheel and like soooooo many others, the wheel was stuck. We used the same method as last year, one person bangs on the center while the other pulls and prods the wheel off. This time it was really stuck so a lot of banging, but eventually came off.
Moved the steering wheel over and all good. Wrong.
Steering wheel was really hard to turn. Felt like my '87 that didnt have power steering.
Here is what we found and how we fixed it.
Looks like all the banging we did, moved the column in a few mm's. Enough so that the linkeage (shown in the picture) was pressed up against the firewall.
There is an adjustment bolt down there so we moved it off the firewall and Voila! Power steering again.
So, if you remove your steering wheel with the "bang it method" and you find the steering wheel hard to turn afterward, check it out.
