I hate loud buzzing noises when the jeep is idling.
Thankfully it's the exhaust system, a bit of moving one way or the other at the rear hanger seems to stop the noise. Now I just have to figure out what the heck it's hitting. My guess is saggyhangeritis.
It could also be the heat shield, but the screwdriver test didn't indicate that as the source.
Now to find out just how hard I'm gonna get loved for a new exhaust hanger. :/
