If that allen-keyed stud rusty, the inside will be stripped. This is a suspension part, exposed to lots of elements, why couldn't bright Honda engineers add a boot or a cap to lessen exposure and rust build up? Or make it stainless?
The right tools mean everything. There is no comparison between an Allen key and an Allen key ratchet. If your Allen key was a .22 Cal, my Allen key ratchet is a .45 Cal.I tried the Allen key on the top one, didn't do squat...the nut just spun and spun. I don't see how it would make a difference on the lower one if it didn't make a difference on the top one.
You guys are not the only ones who ever deal with it. Quit saying you can't do--it's a self-fulfilling prophecy. If you can't even cut it, then one must wonder what else you can't do!
