No not engine knock, but catback knock lol who else had an eBay catback where the farthest back flanges knock against the frame or sub frame whatever past that may be down there? I've had it for about a year and have tried a few things to stop the knocking. If anyone has any wisdom with this and can tell me what they did to stop that annoying problem, please shed light, thank you

 

Walks to front door....

Who's there?

Mechanic

 

Loose heat shields were the cause on my 95'

So it's his axle?

 

Pretty common for ebay catbacks to hit the axle.

 

http://s1303.photobucket.com/user/si...tml?sort=3&o=0 this is where the flange is where it is wrapped a little, it was a temporary fix but it got shredded... Anyway what I'm trying to figure out is a way to keep it from knocking down there. The only way I can think of is to take it to a muffler shop and have them cut it and reweld so the flange would be a little father back...

 

Base on your picture, it seems it's hitting the trailing arm, correct?

 

How about a better picture from under the car?
