The E-class thru 1995 has "normal" alignment CAMS that can change alignment specs by at least 1.5deg for both caster & camber.
If you suspect alignment problems swapping the tires around can be a good idea FIRST!
Also an inspection of ALL rubber suspension bushings is important.
BALL joint wear also will lead to suspension problems.
