Just installed a 8.5" long arm lift and now my front end is roaring. Caster is set at 5 degrease and the pinion angle looks good i think. Yoke end is like 2.5-3 degrease down. The roar starts around 40mph and is loudest around 60mph. But the roar is not constant it will roar pause roar pause roar like something is in a bind. Have put on new wheel hubs left and right and a new front DS with new u-joints. Please help
