OP - So that you understand the thrust button and adjusting the axles better. Stand at either the yoke end or ring gear end of the drop out. Stick 2 long tools in each side of the dropout to contact the thrust buttons. You should be able to press lightly on the tools and feel the thrust buttons slide back and forth, right and left. Now picture your axles where the tools are and feel how adjusting one axle pushes against the non-adjustable side, so when you adjust one axle, you are adjusting both axles.
