I set the car on jack stands at the pinch welds and supported the axle with a floor jack under the pumpkin. I thought this would have been good enough but I guess I should have supported it by the axle tubes with jack stands. The axle has shifted a little backwards and I can't get the bolt to line up now for the new lower control arm on the passenger side. The stock driver side control arm is still connected. What is the best way to move the axle forward so I can bolt up the new control arm?
