Hi Heinz
Thanks for the further clarification, not easy on a technical subject in another language!
What I meant by + + + + is that the 'crosses' or 'spiders' of all 4 of the UJs line up if you were looking along the steering shaft. If I had + x + +, then the second UJ is at 45% to the others.
The uneven steering feel on my car is only really noticeable with the wheels off. It hadn't bothered me as I was told 'they all do that'. It was only my local garage / MOT tester who said it wasn't right.
I think I will take the car back to the local garage to check if something is obviously wrong. It would appear as you say that there is some trial and error involved and the main problem to me is the design of the routing of the steering shaft which makes 4 UJs necessary rather than the ideal which would be to only have one.
