"except pulling the axles out."
This has the possibility of being a huge understatement... be sure to read the shop manual and posts about how to do this.... and don't lose the clip from the inside of the third member....
I think to do this properly and safely that one needs to be able to get the car high in the air and be able to adjust the height of the wheels also.... and there is the possibilty that the third member is supposed to be unbolted and independant control of its height also...
I did not have access to my concrete shop floor, my rolling jacks would not roll of course in dirt... and I did not get my wagon high enough to start with... it was the worst mechanical job in my 30 years of doing it myself...
