I just got done installing sag steering on my 77 fj and before I even road tested the system I ended up with the tierod end rotataing and making a klunking noise. After reading some of the post that are in the search section, most came up with the idea of worn tierod ends or bent rods. Since all the rod end and rods themselves were new, this eliminated this theory. My mechanic came up with the idea of loosening the main tierod clamps and making sure that the ball joint shafts were inline with each other. tightened up clamps and problem was solved.
