a couple of " anyway to fix this problem " questions

[blueb8llz]

it seems like the inner wall has slop moving up and down. oh well. not too worried bout it since its fixed now.
problem 2 is either the tire or rim problem. i put the bad tire/rim on another axle and i used the same hex hub and stub pin as the good tire/rim and same problem...spins in the squiggly line. i put a white dot on the tire to let me know which is the top and bottom of tire, disconnected one of the driveshafts, put the tire onto the axle and spun the wheel/tire by hand. the tire will stopped in random spots...white dot sometimes on top sometimes on bottom etc .. so this let me know that my tire is balanced...if it was heavier on a certain side. the heavier side should have always stopped on the bottom. i hope you guys understand what im saying. so can it be that my tires were glued crooked or something..or maybe the foam inside? anyway i can fix this problem? i glued the other 3 the exact same way and those are perfect. any suggestions?
