Owning older cars means we have to often chase problems. When my rack was worn beyond repair, I replaced it and the difference was astounding. What that ALSO did was make the NEXT weak link more obvious. In my case, it was the slop in the rag joint and the splines to the rack. Rather than beat that dead horse, I decided to replace the rag joint with a steering u-joint. I searched the forums and didn't find anything definitive (other than one person that used a weld-on joint... wasn't going there), so I determined a 9/16"-26 X 3/4" DD joint would work with minimal fabrication.
Removing the steering column is WAY too easy. 2 connectors, 4 nuts holding the column to the dash, and 1 pinch bolt on the rack shaft. When it was out I merely unbolted the lower shaft, cut off the "T" and ground the end to snugly fit the "DD" end of the u-joint. Ground a slot for the pinch bolt (keeps it from sliding apart should it come loose), and re-assembled. If I had a mill here it would have been quicker, but with basic tools it was 4 hours from beginning to end.
The nice thing is the steering is INSANELY tighter with NO slop. There is no increase in transmitted road noise that I can detect, just far more accurate steering.
If you have 4 hours to spare and would like to tighten up the steering a bit, consider eliminating the rag joint for 4 hours work and a $90 investment.
