I'm swapping axles on my tandem axle trailer this spring. My question is about supporting the weight while I remove and replace them. I have 3-ton jack stands, but they don't reach high enough (flipped axles on the trailer) and I don't want to put the jacks on blocks (too high and too tippy). Should I use concrete cinder blocks or giant wood blocks? Also, should I be concerned with their placement on the frame? As in, should I try to place them near where the axles are? Or can I just place them at the far back end? The frame is solid, I just don't want to cause problems by changing the point where all the load is carried. Worried it might flex the frame just a little bit and cause problems...
PS. The axle leafs share a center swing pivot, so I can't do one at a time, all 4 wheels will need to be off the ground.
