I lifted the Jeep about a year and a half ago with the RE 3.5 superflex, full leaf packs. Did the IRO H&T SYE and am running a rebuilt and shortened front DS and 6* shims at the axle.
Anyway, I've always have driveline vibes since the lift, even after the SYE. My shaft is at about 17.5* and the Chry 8.25 is at about 15.5* Seems that should have fixed all the vibes, but I still get some good ones at around 30mph.
So, what else could be causing these vibes? I think that the springs may have netted over 5" of lift in the rear as I had to add 2" coil spacers to get the jeep near-level. Could it be just too much lift for a simple H&T?
Also, where is the best spot to measure the yoke angle? I just measured it off the rear of the diff at the bolt heads, assuming it was 90* opposed to the yoke output.
