Driveline VIBes with LOCKERS?????

I just installed a RE 3.5" lift on my 99 with a NP231 and Chy 8.25. I used 2 degree shims and 3/4" of trans drop. My vibes are not bad but there is still some what of vibes. My question is will that affect my Powertrax NO slip locker that i am planning to reinstall into the jeep? I know SYE but i would rather avoid spending the money right now if i could. let me know what you guys think about this. Also i am thinking about going to a 4 degree shim. What is recomened for my setup? Thanks

Been there done that,a 4* sounds closer but you really need to check the angles!I wish you luck because I have "NEVER" gotten rid of my vibes(2 SYE kits later),Im going to a D44 to hopefully put this to rest.
