This is what I tried to tell you. On the rear you hold the nut with an open end wrench\box head or crow foot head on a socket. To keep the endlink from spinning you use an allen key in the threaded body, this is why you need a wrench not a socket.

However, You would need a crowfoot socket head or similiar part to get down into the front nuts of the endlinks in the lower A-arms. I didn't have one, my threads also rusted up bad, so the dealer had to cut mine off at the a-arms and then installed new ones, they are cheap enough.

I would also install new rear endlinks if I were you too, Honda has a TSB and new rear endlinks for all 98+ Accords, TSX uses the same endlink so I figure it would need them too at some point. I have yet to replace my rear links.
