help wanted - Power steering racks (ZF)
Hi gents,

I'm urgently looking for any kind of information, diagrams or documentation for the ZF steering racks found in e90's and 1 series. I disassembled my old rack to see how it works, and wasn't really paying attention to the control valve orientation, as I wasn't going to reuse it.

Now the replacement rack I bought is leaking, and I have to refurb and reinstall the original. The shaft that sits inside the control valve body can go in one of two ways as it is.

I need to know which way to line the two up, I will try and take pictures on the weekend to explain the problem better. As you can see by the image below, if I insert the shaft incorrectly it won't work.

Or does it not matter ?

I would appreciate educated opinions.

Thank in advanced.
