Unfortunately, the problem (incorrect tie rod ends & sloppy mechanics) isn't limited to the Benz. I found 2 tie rods of the same side when refurbishing my 78 Datsun Z. In that case, the only effect was that the adjuster had to be turned in the opposite direction when setting toe. I also learned that an entire reman steering rack could be purchased for less than 2 inner tie rods. Gotta check prices when deciding between bushings only & a whole new part. Now to learn the intricacies of the SD suspension.
