To adjust preload on the worm shaft (part column attaches to) you MUST remove the box from the car. Follow the factory manual exactly! If you get this even a tiny bit too loose, you will have massive slop in your steering. Too tight and you'll destroy the box. The sector can be adjusted on the car, BUT it is better to do with the box removed. You MUST disconnect the pitman arm from the center link as a minimum. Your target is to "just" feel the box tighten up with the wheels straight ahead, it shouldn't be sticky. Too loose and you get some slop. Too tight and the box is ruined.
If you are feeling to lazy to do this right. DON'T MONKEY WITH IT!!! This is a matter of safety for youself and others.
BTW, a lot of reman steering boxes are junk. I would rather have a 200,000 mile original thats never been f**ked with than some parts house special that's had it's preloads all jacked up.
