Yes, got the old wheels off easy. Just pried off the plastic red cap wit ha crow bar and the wheels slide right off (along with a couple washers). Just waiting for the new wheels from Amazon. One will be here tomorrow, the 2nd hasn't shipped yet..., hope it doesn't take too long. Looks like they had to get them from the manufacturer or something....
No, of course there was a big stainless washer on either side of the wheel, with a cotter pin on the outside and then the plastic cap which is basically just keeping the dirt out, and the grease in.
