loud humming in axel

I just lifted my 96 zj 5.2 v8 limited, 4 inches and I'm now getting a humming vibration when I hit 45kms and 80 kms anyone know how to fix this?

And does anyone know why, when I take off hard it shifts for the first few gears but at around 4900 rpm and 98 kph, its like the tranny disengages or something cause it will keep rapidly reving but not go, till I release the gas and re apply it. The red line starts at 5300rpm on my truck and theres no slipping in the tranny anytime?????

Bad pinion angle is likely the culprit. Sounds like it's time for adjustable control arms.
