I had a rattling under the truck. Turns out to be the outer cover of the converter had separated, and one side was dagling and hitting a cross member. Well, I separated the other side and removed both pieces.
My question, what purpose is this outer cover? I assume it is some kind of heat shield, but is it detrimental that I removed it? I saved it to put it back if need be, but my driveway is all ice and I was too wet and cold to fix it correctly.
So, I guess my question is, should I make the effort to replace it when the weather permits? It's a '96 F150, and it looks original.
