2004 Jeep Rubicon, 4 inch Teraflex- Bad vibration above 35 when in 2L. Switched to 4 wheel and 90% of it went away even when doing 60 mph. After going off road vibration back at any speed in 2 and 4H. Really bad in 2L. or when taking foot off gas . There is also a high pitch whining.U joint seems smooth but needs some lube. Any ideas.
