Hello - I have searched most of the threads concerning this. It is actually quite simple and have adjusted the proper screws however the steering does not seem to be getting much tighter - still very loose.

W123 1983 300D Turbo

Concerning the steering and suspension I have replaced:
front upper control arms and bushings
front lower ball joints
drivers side and passenger side tierods

note: I have not had the alignment done yet (Wednesday is my appointment), will this tighten my steering - am I wasting time adjusting the box - should I wait until aligned?

I was able to turn the 6mm screw all the way ccw until it seemed to be stuck - then loosened it a half turn cw - then tightened the 19mm lock nut while holding 6mm in place.

is there something else I am missing or should or could be doing? another adjustment somewhere else. Do I need to replace my Steering Box and how would I tell. It does not seem to be leaking.

Thanks for your responses - I would like my steering tight and straight!
