FWIW, the pin-drives on the rear end of my ERA are "snug" also. Front wheels slide off relatively easy. Rear wheels have to be wiggled side-to-side to get them to slide off the pins. I guess this is a good thing as there is just about zero freeplay when the wheels are on and the spinner tightened, but it does take just a bit of wiggling to get the rear wheels off. I have not had to lubricate the pins with anything yet. although I make sure to keep the spinner and threads well-lubricated with anti-seize. I also have on of Mr. Enzo's magnificant spinner removal tools which I find I need periodically. ("Enzo for President")
