99XJ 8.25 np231 auto
This all started when i built a big bastard pack. Ended up with about 3.5" in the rear. Installed a T-case drop. Had vibes from 60mph up.
I later pulled a couple leafs from the pack and put on a set of shackles. I ended up with about 1.75" over stock. I pulled the tcase drop then. I had vibes from 65mph on. Getting bad enough at 70 that you can hear it not only feel it.
I now have a tapered 5/8" block and my pinion angle and tcase output angle are within a degree. Probably half a degree down at the pinion.
I still have the same exact vibes that I did without the tapered blocks. I would think it would at least get worse or better with the change. Any ideas what to do next? I really dont want to put an SYE in for a 2" lift. Vibes arent liveable at highway speeds so I dont think I have the normal vibes.
