Hi,
I recently picked up the Sandcrawler and I have ran into a difficulty with the rear wheels. They will not turn when I spin the wheel. The mechanism seems to be working perfectly up until I attach the wheels, then it is hard to even spin the wheel, and the back wheels barely move at all. I have taken the thing apart a couple of times and tried everything I can think of...I am dumbfounded! Does anyone have any advice or any idea to what is wrong (or how I messed up?).
