OK, I took the lugnuts off one by one and wirebrushed the wheel studs and lugnuts and wd40'd them because they were rusty already. Turned out to be only surface rust but the plastic center cover fell off. When I put it on it wasn't tight like the others (Spins). Do I need to take the wheel off and install it from the inside? BTW, it's 73 degrees and sunny today but my wife had to work at my son's drama club and I have to babysit. Oh well, we rode bikes a lot but now I'm stuck inside while my 3 year naps. I WISH I WAS CAMPING!!!
