speaking of idler arms, yesterday I got a wild hair, and decided to strenghen the idler arm mount and build a lower support for it as well. (This is for the Tracker.) I removed the mount and boxed it in with steel plates in the open areas to strengthen it, then made up a lower support bracket that bolts to the A arm mount and connects to the bottom of the idler pivot, similar to a Calmini support.  All was well there, But when I tried to remove the idler arm itself I couldn't budge the thing. I tried a couple of pullers but really couldn't get a good bite under it. I've lubricated it with some kroil ( serious penetrant) and hope to take another crack at it later. I want get it off so I can maybe make up a stronger one, or strengthen this one. Any tips on tools or tricks to gettin' it off?

Did you ask it nicely to just come on off of there?

If nothing else you can try heating it with your torch.

  I asked it, not very nicley I'm afraid! I will give it some heat and see if that helps. Thanks BigPig.
