W124 Alignment PDF / Document?
 

I was looking in my 124 service manual but didnt see it, maybe I missed it..

Is there a document somewhere they lays out the specs and procedure for it?

MBNA publication S-2350-124 "Service Manual, Chassis and Body, Series 124, Volume 1" -Section 40 "Chassis Measurement, wheel alignment"

Imperative that you get side to side ride height within factory spec to assure correct alignment settings.

Thanks! I thought I'd overlooked it.

Here is the direct link to the document on StarTek

It does not mention any procedure to follow, or the spreader bar. I saw a W469 (?) WIS document that made specific mention of the spreader bar.. Is there an WIS document similarly for the W124? I don't believe I have access to WIS..

Not many adjustments to the 124 chassis especially in the rear.
Kind of basic
As I stated the ride height differential side to side must be within tolerance or else you'll never attain a suitable rear camber which is non adjustable and changes with static ride height.
