What kind of lift? It needs to be on a 4 post where the wheels are.at ride height (2 post will have the suspension drooping)
Remember what I said in my PM. The trans angle and the pinion angle need to be the SAME but opposite angles. IE: if pinion is infact down 3 degrees, that would be -3* trans needs to be up 3*
What is the trans angle? "Flat" isn't a measurement.
