So my teg has a vibration under acceleration. It's intermittent, and really only about between 2-3000 rpm. I've replaced both axles and I know that it's definitely not unheard of to get a few unbalanced axles, and I've warrantied the left one twice; and like I said it doesn't happen all the time. I'm kinda stumped... Wondering if diff bearings are misaligned? Maybe a case/bearing shim issue? Any thoughts would be appreciated
