hi k,
no worrries abou the fabric, its already torn from my first ride with the 2 girls. a few more black marks wont make much difference! I did exactly as u said - flipped the wheel and inserted the new axle. the wheel was dished to begin with. i dont need to fold the trailer so that shouldnt add stress.
I dont need any more stress! I have enough stress using wonky trailers trying to get my kids around!!
