This is my buddys land cruiser, he's been chasing this steering issue for a while. Heres what we've eliminated: tie rods, rod ends, steering box, alignment. All of it gone through and checked. You can see in the video that it seems to be harmonic. As he accelerates quickly about 3 minutes in it misses the death wobble, but as he decelerates back through those speeds it picks it up again. Really strange and we just can't seem to track this thing.
