    not lowering t -case w/ 4\"

    i have an 84k5...when the 4" lift was first put on the t-case was not lowered, there were no vibrations. Howerever the front driveshaft did not clear the crossmember, so I ended up lowering it. I am going to modify the crossmember so it clears the driveshaft, will I be ok in the long term without the lowereing kit? Its got a 208 and the stock shafts. Thanks for any input.

    You should be ok. So are you just going to lower the crossmember to clear the shaft?

    Re: not lowering t -case w/ 4\"

    I drove mine around for about 3 months before I lowered mine. I was hitting the exhaust. I thought it was no big deal. I changed my gears and rebuilt my c-v joint at the same time. About a month later my C-v joint blew out. It was because it was hitting the exhaust and would put a wierd bind on it. I fixed the exhaust and lowered the t-case now.........Dan

    If it ain't broke.......Don't fix it....

    Re: not lowering t -case w/ 4\"

    My truck has had a 4" lift on it since January and I still haven't lowered the transfer case. It's somewhat annoying to listen to the crossmember rub the driveshaft but I'm just too lazy to do it. I guess I'll do it when I swap my frame out.

    I've never lowered mine, and I run a 4" Superlift. My driveline never has rubbed (knock on wood), so I'll just leave it be.

    Re: not lowering t -case w/ 4\"

    I agree with riz. I drove around for a few months before I lowered it and it was always in the back of my mind that I should. You just feel better once you do. I did it by my self in less then 20 minutes. It is easy.......Dan

    <font color=purple> It should be just another step in doing a lift, like putting on the shocks, ya know what I mean ?

    Re: not lowering t -case w/ 4\"

    I guess my post is somewhat unclear...My driveshaft is rubbing now and i already have the transfer case lowered...I'm going to cut a hole in the crossmember so it clears...I figured I might as well get rid of the drop and gain the 1" of clearance back.

    Re: not lowering t -case w/ 4

    I'd say you'll be fine. If you didn't have vibes before &amp; you're modifying the cross-member to avoid the contact, then why lower it?? It's only robbing the ground clearance that you put in a lift &amp; bigger tires to gain! As far as the angle on the u-joints, the difference in an inch is minimal &amp; if there's no vibes, then things should be fine.

    Just for the record; I'm putting in a 6" lift on my custom frame &amp; I'm NOT going to lower my t-case. If anything, I'm going to try to raise it to be flush with the bottom of the frame rails. I'll also be stretching my wheelbase a few inches to help with driveline angles. Like I said; I just can't understand why you would raise a vehicle &amp; lower it's undercarriage??!!?? [​IMG]
