I was looking at the steering and suspension section the e34 repair manual on bmwtechinfo.com and noticed something that may greatly affect the wander some of our cars are afflicted with.

Section 32 21/8 mentioned that steering drop arm (aka steering pitman arm) when adjusted correctly optimizes directional stability on rough road surfaces. It mentions the use of special tool 32 2 120 to insure that the “steering drop arm” is aligned correctly

Following is the link to http://www.bmwtechinfo.com/repair/main/741en/index.htm. This is the main page of the manual

Has anyone had this adjustment (or similar) completed on his or her car?
