First Guess: Once you have it all apart far enough to lube them...you'll discover that the roller elements and the races are scarred from lack of lube, and they just plain need to be replaced.
And that's fine...but then you figure you might as well replace the struts while you have it apart. And if you're gonna slap struts on it, you might as well upgrade the springs. And the control arm bushings, and sway-bar bushings. Which is a perfect time to check and replace the ball joints if needed. By that time, the brakes are apart, so replace the calipers, check the rotors and pads for wear, and deal with whatever you find including the brake hoses and maybe the ABS wheel-speed sensors and front hubs.
Well, you have it that far apart, so a quick-ratio rack 'n' pinion with fresh tie rod ends isn't so much more work, and that means flushing the PS fluid, too. Some folks think a real PS cooler is a good idea--better than a bunch of tubing looped back-and-forth like the OEM "cooler"...
