Finally found the rattle in my exhaust just don't know how to fix it. It appears that the springs that hold the hanger bracket is hitting the diff. I can see some small rub marks on the diff next to the spring. Anyone have a suggestion as how to fix this problem ? I tightened up the bolts that hold the springs and the rattle is not as bad but still can hear it. Anyway to insulate the springs from the diff ?

I also put a spring between the springs to increase tension but still no help with the rattle.

Loosen all the clamps and adjust system for more clearance.

My '11 just started doing the same thing last week. I tracked it to those springs because when I hit a tailpipe I can hear those springs rattling. Hafta get underneath and adjust.
