I have an Idler arm I replaced on my Escalade. I know that it had less than 30K on it because I did it and I've only got about 30K of my own miles on this truck. Rando bad part or do I need to start looking elsewhere for stuff? The guy at the auto shop said "You should put Moog on it, they never fail" and I was all "I'm pretty sure it was a Moog."
