I don't know if the test procedure is on the forum. I can email you "32-0530.pdf" (324k) "Testing pressure oil pump and level controller..." It notes nominal pressure at level controller of 133 bar. There are 2 other pdf specific files and many more relative ones. Unfortunately, there's a lot of redundancy and the info has specs using MB alignment tools. Ironically, in one sentence it mentions the fender lip to center of axel measure. But I've never found actual numbers.

My inde's alighment rack is not avail, so I'm gonna take mine to a speciality alignment shop and have tehem check mine.
