I went for an alignment yesterday (not an MB shop but a very reasonable and knowledgeable shop) and literally spent time with the alignment guy under the car, he has a fancy hunter laser machine, but the data for the w124 in that machine was incorrect (its incorrect in all of them according to the operator), when we chose the base model it was giving specs for an E420 or E500 I think.

So I used the factory manual specs for my car which were

camber 0° 5'
caster 10° 10'
toe 0° 20' - with spreader bar (two pieces of wood slightly cranked with a jack)

Dialling in the caster and camber requires constant toe adjustment unlike regular cars, we got the caster dialled in exact dead correct but the camber on the right could not be dialled in (the eccentrics were fully cranked in) and still we had +1° 3' camber. with zero toe

What can cause this - worn strut mount? or sagged spring? - we went around and checked the car, it was completely level and he used a tool to measure the arm angle - it was similar on both sides.

I inspected the spring pads and found two nub pads on both sides on the front and both the strut mounts show very fine cracks at rest.
