Default gear swap now whine and VIBRATION

I recently had Richmond 4.10's installed in my 10-bolt and now i have the expected whine but theres a vibration starting at around 60-ish mph and progressively gets worse the faster i go. I had absolutely no problems as far as vibration goes before the gear swap (could go up to 160mph with no trouble).

My question is what could cause this vibration?? Im gonna swap in a different driveshaft soon and see if that helps but i dont think it will.

180 the driveshaft see if that helps if not you can try clocking the yoke differently on the pinion if you get your highsides of run out all lined up it can cause problems... as far as the whine goes you'll just have to live with it aftermarket ring and pinions are built for strength and performance not creature comfort...
