I'm at a total loss

copmagnet · Jan 5, 2014

So I'm driving down the street on a nice midnight cruise, I downshift get that nice bubbly exhaust sound and then BOOM!

I was like what in the world! I got my car home and got it up on stands and found this:

I'm thinking my muffler bearing went bad, but I'm not sure how, Its a pre-greased bearing from napa, and it's only got 200 miles on it! I called napa and explained the situation and they told me I should be running a water cooled muffler or the heat could liquefy the grease and cause it to drip out of the bearing. They also claimed it could have failed because I didn't use a muffler bearing alignment tool when I installed them.

Should I try a different grease or use the dealer supplied OEM lithium/beryllium bearing grease? should I get new muffler bearing or get a muffler bearing master rebuild kit? Will a ceramic muffler bearing last longer then a normal mb?

Is there a way to pack new grease in with a normal screw driver? the instructions call for a left handed screwdriver but I only have right handed screwdrivers.

What do you guys think I should do?

Damn, that a lot of back pressure.
Are you sure someone was using you exhaust as a potato gun?

On a serious note... I've never seen a muffler do that lol

First off, you should be running a liquid nitrogen cooled muffler. Obviously.

Second, you should be using a good eBay muffler bearing with a francium bearing grease.
