I have an LJ, so its not a direct comparison. But, I had to drop my transfer case skid about 5/8" to get rid of a slight driveline vibe when I did a 4" lift. By installing the MML, I was able to eliminate the transfer case skid drop completely.Guys sorry, I wasnt taking about vibes at idle. I am having some driveline vibes at low speeds such as 10-30 mph
