I have a 77 W 123, is a 240D. The steering box still has 3-4 inches free play. Don't think it has improved after tighten the allen nut and bolt. Undo bolt then tighten the allen key.

My other w 116 300SD had this done, it got a lot tighter.

Any suggestion? Get another steering box, or any rebuild kit avail?
