Our muffler on our Case IH 4420 sprayer goes forward and back around 0.5-1 inch while the engine is running. It does not look like the muffler is broke or the clamps loose. Has anyone else had this problem? It almost looks like it should have a brace to help stabilize it. Any help would be appreciated. Thanks SouthernSK

Mine was cracked underneath.

I maybe should take it off to look at it better. Thanks Bud.

Has anyone had success rewelding them?

Put a 1688 exhaust on it

I took the muffler off today and it was cracked on the bottom. I rewelded the bottom and welded in a second set of support plates on the very bottom. Hopefully it will last for a while.
