Are there tie rod bushings on a 93 190e 2.6L
 

I would like to know if a 93 2.6L 190e have these bushings and if yes where they are and how easy they are to replace.
Thanks,

There are no "bushings" on the tie rods. The tie rods have ends that are a ball and socket type joint. They are relatively easily replaced and the complete tie rod with joints on both ends for each side cost about $40 each. After you replace them, you must see that the toe is correctly set.

Good luck,

IF you're thinking of the front tie rods, then Larry said it. They are generally easy to replace and a DIY.

IF you're thinking of the rear tie rods, there are bushings that go to the subframe. The rarely go bad, and if they do, replace the entire part. MB does sell the bushings separate but the time or tools involved are not worth it IMHO.

Alignment is required & the dealers generally do it best.
