Horse ---in the old days Mechanics would say, that if you feel it in the steering wheel it was in the front end of the vehicle and if you feel it in the seat it's in the rear of the vehicle.....not sure if this still holds true---but if it does it might help isolate the problem.....Shocks ,springs, bushings,loose parts, Alignment,Tire/wheel balancing,driveshaft and pinion angle, trans and motor mounts......maybe the axle or axles are still not right.....
