OK, so you're saying you get vibes at 30 and 65 only when in 2 or 4hi? Or only in 4hi? Write a little clearer please.

vibrate at 30 to 40, eases off the comes back at 50-65 then smooths out. If i pull it into 4wd hi it drives perfect through all the speed ranges. But as you excellerate or dcellerate the vibrations comes back like you fliped a switch.
It can't be tires or pionion angle because it smooths out when in 4wd hi. Remember I put it 4wd hi and then put it back in 2wd all in one motion.
