Hammering the piece back to where it belongs is actually not a bad idea. That is, if it is indeed out of whack. If it bent at all, I would say it is minimal, so heat it up orange hot and hammer it back into position. I think with a straight lower control arm, you will find out if it is bent a little. I think getting the LCA to line up right will be difficult, making the damage apparent.

PS - SAS....SAS....SAS....always a novel idea, but I have yet to see a good looking SAS on ANY Isuzu....but this is just me. Things get a little funny looking with a SAS, IMO.
