    Ok, I am back with an update on my situation. I had gone from the 4" lift to a 6" lift last week, and also installed my 14 bolt in the rear. I had never had any vibrations with my 4" lift, but had really bad vibrations with the new 6" lift. So I changed the shims around 180 degrees, and that seemed to help, but was still bad. Well, yesterday I had my front ARB installed along with 4.56 gears by Drivetrain Direct. They lowered the t-case at the same time and experimented with the shim (took it out, then turned it around, etc). It does drive much better after the lowering of the t-case, but still has a noticeable vibration when getting off the gas at anything over 65 or so...not bad, but you can feel it. So, they had said that a possible cure was to have a custom driveshaft made that uses a "Cadillac style" CV joint at the slip yoke end? Has anyone heard of this before? Supposedly this style CV works with the in and out motion that the slip yoke has to provide. If this is the easiest way to cure it, I would like to do that. I just want it over and done with! Any other suggestions?

    I've never heard of the cadillac part, but a CV driveshaft is about the only sure fire way to get rid of those driveshaft oriented vibration problems with lifts. I had all sorts of crazy vibs with just a 4", but like they keep saying, every truck is different.

    I miss my Ex, but my aim is getting better!

    But is a normal CV type u joint compatible with the slip yoke 208 t-case? I keep hearing that it won't work, except supposedly with this "cadillac" style joint. Anyone know anything about this??

    if the vibes are at 65, I'd suspect the u-joints are going south, thats the only time i could feel them doing that on mine
