DONE! rack moves no more. Solid as a rock! I haven't test driven it yet, but I bet it will make a huge difference from the 3/8 to maybe even 1/2 inch it was shifting.
For a 2000 4runner, the parts I posted early work perfectly, with no need to drill anything out. The hardest part was prying out the old bushings
The directions tell you to remove the DS tie rod, but I had trouble with that. I managed to replace all the bushings without removing it though. It just took some clamps, and a little bit of work.
NOTE: I have no auto mechanic experience at all. I did it myself, and so can you. Just be patient when you press in the new bushings, as they are tight and tend to bind and catch on parts. I had one twist up on me, but I noticed it and fixed it.
