I've got a really loud squeak that comes from the hangers on my catalytic converters. I can push up and down on the cats and hear it and it makes a lot of noise over rough ground. It seems to go away when I lubricate the rubber hangers above it. So, the questions are

Is there a permanant way to fix this problem?

If the fix requires a cat replacement then how hard is that to do myself? I don't know much about the O2 sensors so I don't know if they're in the cat or not in a '91 Navajo and, if so, how to deal with them

Thanks
