    You might try adding some 1" spacers beteen the crossmember and frame to lower the rear output of the t-case a bit. I ran mine like this for a long time when it was a dd. One down side to this is that it makes your front driveshaft angle a bit steeper. Not so much a problem on the front though.

    Are you angles correct? Get it fixed and drive up here by me and we can do a little wheeling

    2 things one has already been mentioned by dropping your t-case and also make sure your driveline is balanced if it is not you will burn up u-joints like there is no tomorrow the angles also do matter alot so i would check all of the above.

    i have a 76 w/6in lift .rear pinion prolly needs to get rotated down.i'm going to get a cv joint in it.should fix it.since its a 76 its prolly full time 4x4 so u don't want a worse front drive line angle by droping the T-case imo

    thanks eveybody for your replies....i already have the 1" spacers for the transfercase plate....how can you check to see if the angle is correct? i am currently in the process of converting the full time np203 to 4x2 with the conversion kit...since the drive shaft will be out , this would problably be the best time to make adjustments...i am also looking into the c.v. jointed drive shafts as well..anybody know where i can pick one up or how much they run???

    I have a '90 K5 and just put a 4" lift on a couple of months ago. That thing vibrated like crazy. I hated driving it. Yesterday I got my new shaft with a CV joint and now it drives perfect. No vibration at all. Definitely the route to go.

    Got mine from Rye Valley Oil and Gear in Sugar Grove, VA. I'm from MS and they came highly recommended. Ask for Ronnie. He was a great help. 866-793-6451
