Question I have a 4wd Tamiya nitro on-road Mini cooper Racing, and for some reason the
car won't roll forwards, and when I take it off of the ground, the front and rear
wheels seem to be spinning towards each other. Thoughts?
Answer Hi Cameron,
I sounds like when the car was reassembled that one of the differentials was put in upside down. This has shaft drive, right? Whichever one is spinning the "wrong" way is the culprit. Take apart the diff case and flip the diff around and you should be all set!
