Hello,
I'm sure this isn't a new topic, but I cant seem to find a solution to my drive line vib woes. I currently get vibes starting at about 60+ mph and it's important to note that I drive quite a bit on the hwy, esp with inter coming. I have a 3.5" OME lift, that turned out to be closer to 4". I have full leaf packs in the rear with 4 degree shims, Double Cardan drive shafts all around, a rusty's 1 inch t-case drop bracket, and stock control arms.
After measuring, the front pinion is angled 3-4 degrees below the center-line of the drive shaft....seems like a lot to me. I assume I would have to get adjustable control arms to fix this, unless I added more t-case drop in addition to the Rusty's 1 inch lowering cross-member. Is the t-case shift linkage the limiting factor on dropping it more? I've been messing with the rear pinion angle and have shims that are a little too big. I'll take them out and try to get the angle 1-2 degrees below the center line of the drive shaft when at rest.
Also, the front and rear shafts slope downward at 11.5 degrees and 12.5 degrees, respectively.
If anyone has experience with this, I would greatly appreciate some ideas. Thanks
