Thanks, that is exactly what I was told by a friend that saw the car yesterday.
I was thinking to get an old upper link and extend it a bit (it would probably cost less), but first I want to make sure that this is what is causing the vibes, i'm starting to think that I have a problem in the transfer, and that the lift just increased it, since after a short drive (20 - 30 minutes) the vibe are becoming less noticeable, i think it be cause the transfer oil (or the diff's) gets warmer, does it make any sense?
