i have this crazy interior vibration sound on the right side of car near the front of the door when acceleration at low speeds. Sound goes away at higher rpms?

Thoughts?

 

video wouldnt load. my blind guess is motor mount.

 

Check your heat shields for the exhaust around the cat. to see if they have come loose.

 

motamounts.

 

Does it present at idle but disappears above 1500k or so? Motor mounts.

 

Its hard to tell from your video what is causing that sound. Is it just a virbrating sound or are you feeling actual vibration? Is it happening only while you are moving or when you are also just stationary with the engine revving? Has the vibration always been there or did it happen after you did some work like changing the balance belt?

I embedded the video below for those that said they couldn't see it.

 

It is mostly a sound. It happens at low rpm after you start accelerating. It starts at a certain RPM like ~1200 and goes to ~2000. No noise when idling and stopped. The vibration has been around for while. Just starting to try to sort it out.

It sounds like its coming from the A pillar somewhere (but could be the door).

 

Maybe the plastic rain tray came loose and is rattling? Or else something else is rattling in the battery tray? Get a friend to drive while you sit in the passenger seat and prod around to see if you can feel the vibration. Or maybe by touching an area you can stop the rattle (and thus locate it).

Rattles on my cars have always been heat shields (around the cat, below the headers, etc).

 

I had a vibration sound that turned out to be the corner of my hood tapping the body. Hood adjustment and proper placement of the rubber damper in the fender channel fixed it.

 

Cats gone.

 

UPDATE:

I went out and listened some more and the sound does appear while reving the engine at idle too. Not as loud or noticeable and I can also feel the vibration a little.

How can I tell is motor mounts are bad?

 

You can measure them in-situ:

 

So, I measured the height of the right mount and it looks like ~60mm. Don't see any substantial cracks in the rubber.

 

So now you know.
