What you you mean by "the bolt"?
There is an easy adjustment for slack on these steering boxes. It's not the ONLY adjustment for slack. There is another slack adjustment that's a pain in the ass to make, and they have to BOTH be correct.
The steering shaft isn't (usually) the problem, the rag joint at the bottom is.
Amen, the internet has all kinds of examples of the gear mesh adjustment but almost nothing on the worm gear adjustment. I wonder how many guys are trashing their gear box trying to adjust the easy one not knowing how to do it right.
I bought a reman Delco box and had to adjust everything before it was right. Next time I'll buy a quality box from Lee Manufacturing, Benchworks or try Redhead. Well worth the extra money IMO.
