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?
