Dont know if this applies to front drive line but when I installed sye and new Tom Woods drive shaft I still had vibes. Drove me crazy till I did research and found that the driveline could be 180 out. Turned 1/2 turn and vibes gone. Might try front. Food for thought, Good luck. Hate vibes.
I’ll try that, just second guessing cuz ive uninstalled so much already lol thanks
