To remove the upper control arm shaft and the lower control arm shaft, it is as straight forward as pressing out from one end until the shaft is far down enough to pull out? Or is there a special trick that someone could recommend?
It is that simple. Usually takes a press with a bigger throat than a twenty ton Harbor Freight press to get the parts aligned. If you are not careful you will bend the A-arm and that will create a problem, if the bent A-arm is not replaced.
You can burn the old bushings out with a torch and then the bar will just fall right out. I didn't have access to a hydraulic press, so that is how I did it. Easy and there is no risk of bending the A-arm as Dave mentioned. There are a few YouTube videos showing how to do it.
