Because a sway bar is basically meant to jack weight from one side of the car to another, my ideal way to adjust it properly (haven't done it on THIS car yet) would be as follows:
Drive the car until the fluid in the shocks have gotten some use so the fluid has at least some chance to warm;
If a bolt hasn't been previously removed from the end of ONE rod end, remove one bolt and loosen the lock nuts on ends of the rod ends on the other rod;
Place car on a level surface with about half a usable tank of fuel, fluids topped off and other normal weight is in (ie driver weight);
Roll car back and forth and "bounce" car slightly in the middle to help everything settle;
Adjust connected link to get sway bar at proper angle (so it can move freely under load, probably level) and there are at least 5? threads of each rod end into each link;
Adjust link with one bolt missing from one rod end until the missing bolt can easily be inserted;
Insert and secure bolt and tighten the lock nuts against the link ends,
After this, unless the rod ends are new and the balls really tight, you should be able to grab the rod between them and easily move it. It will almost feel "sloppy";
Remove sand bag/ dead weight/ girlfriend from drivers seat;
Drive it like the bank owns all of it.
Some time in the future, with about the same amount of fuel, driver weight, fluid levels, parked on the same level surface, etc. try to wiggle one of the sway bar connecting rods. It might be a little firm, but it shouldn't feel like there is a lot of load on it.
