Idler arm removal
Thanks for the suggestions, all. I've tried the BFH approach, although I may see if I can jack the car up higher to get an even BIGGER BFH (would that be a RBFH?) on to it. I hadn't thought to reconnect the driver's side tie rod - that may provide the pushback, so to speak, that I need.
I think the Autozone rental approach is most likely the way I will go - I'd rather not do any more hammering that I have to. We'll see how it all goes, and I'll report back once progress rears its head! (Or I hit mine against the wall, whichever comes first.)
Thanks again!
