Hey guys, just picked up a nice honda but the axle bolt on the rear left side keeps coming loose after and during rides. I noticed when I bought it there was what looked like grease stain around the axle on the back side of the tire and the tire itself was slightly loose. I figured the bearing was going, but I haven’t noticed any noise. I bought a socket for the axle bolt and tightened it up. It was very loose. But I thought that would be the end of it since it tightened right up and felt very secure.. Well, as much as I can hand tighten it, she keeps coming loose to the point of breaking the shear pins off! What the heck is going on here? This is dangerous. Bad design imo!!
