I'm hearing a loud vibration in my 2012 Mustang 3.7L, when moving or stopped. I traced the vibration to these raised sections on the floor. I can feel it at the same spot on the passenger side. What is under there that could be vibrating?

 

Does it shift alright? Auto or manual? Do you hear any exhaust leak from the outside?

 

Its and manual and I can shift just like normal. I don't think I can hear and exhaust leak from what I can tell

 

Cat Converter Heat Shields!

Although Pic is of Boss 302 Exhaust. Cat Converters are Likely in Same Genereal Area!

Also Check Dampening Brackets on Cats!

That's My Guess!

V6 Cat Converter Has Dampening Brackets

 

Wow what a picture. Thats could help a ton! The rectangles on the front are exactly where I think its coming from, like up inside the frame. I have a video that highlights the sound well. .

 

Loose Clutch Disc Dampening Spring Perhaps???

Just a Thought!

Cat Converter Broke Inside Could Make Some Odd Noise as Well!

Likely Gonna Take Some Poking & Proding!

The area you circled inside it right above where the trans mount is, chech to make sure the trans mount is not going bad.

 

Wonder if a Solution was Found!



Mgb,

I forgot I posted this here! The issue was actually a rock stuck between the transmission mount and cross member. I got a new trans mount based on your reply, and as I was changing it out the rock fell out. It put everything back together and the car sounded perfect. Its always the dumbest things!

 

Thank you for the update and providing very useful info... No doubt this will come in very handy for those looking for a solution to be on the lookout, down the road.
