andnyleswillriot Posted April 3, 2013 Share Posted April 3, 2013 Hey guys, So just recently in the past 4 days every time I start up my car I get an odd noise as if something underneath or maybe even around the wheel area is shaking or vibrating against something. Once the car sits at idle for about 20 seconds the noise goes away but comes back again once I start accelerating. Once I get up to about 35 mph it goes away entirely and doesn't make any other noises beyond that. The only work I have done before it started happening it switching my two front wheel positions when I painted them (I switched them back to no avail) I have a 2009 2.5i SE with only 42k miles (and only 6k since I bought it certified pre-owned from subaru) so I have a hard time believing it's something serious. No CEL's or anything out of the ordinary, just a very odd vibrating noise that's really annoying! thanks for any help! Link to comment Share on other sites More sharing options...
_karu_ Posted April 3, 2013 Share Posted April 3, 2013 Does it sound like metal rattling i.e. rattling loose heat shield? Link to comment Share on other sites More sharing options...
andnyleswillriot Posted April 3, 2013 Author Share Posted April 3, 2013 I guess you could say that, it's kind of a deeper toned rattling. but I'll check that, thanks.\ edit: starting to think it could be the same case as this: http://legacygt.com/forums/showthread.php/easy-remove-heat-shieldi-161318.html Link to comment Share on other sites More sharing options...
_karu_ Posted April 3, 2013 Share Posted April 3, 2013 Thanks for pointing that thread. I also have similar issue. I brought the car to reputable muffler shop in my area and they actually did not find loose heat shields. The annoying thing is that, the noise isn't constant. I have to rev the car to get it to rattle. Therefore, it's not easy to pinpoint the rattle. However, as the picture in that thread shows, it could be the metal "ring" inside the heat shield. This is definitely worth taking a look. If that's not the case, it could be something above the front under cover. Link to comment Share on other sites More sharing options...
andnyleswillriot Posted April 4, 2013 Author Share Posted April 4, 2013 yeah I'm having a hard time pinpointing where the rattling is coming from with the naked eye, hopefully get it up on the lift to take a look soon. After driving some more the noise is getting what seems to be more inconsistent, which makes me think it really is a heatshield rattle or some sort of rattle. might take it to the dealership to take a look if I can't figure it out Link to comment Share on other sites More sharing options...
andnyleswillriot Posted April 4, 2013 Author Share Posted April 4, 2013 anyone have any other ideas as to what it could be? Link to comment Share on other sites More sharing options...
08SpecB_DE Posted April 4, 2013 Share Posted April 4, 2013 Sounds like a heat shield to me. Link to comment Share on other sites More sharing options...
_karu_ Posted April 4, 2013 Share Posted April 4, 2013 Without opening the front under cover completely, I checked the heat shields coming off of exhaust manifold. I did this by opening the cover for the oil filter and use mirror to look up. I tapped the shields with screw driver and it was not rattling. The problem must be something else...

08SpecB_DE Posted April 6, 2013 Share Posted April 6, 2013 Have someone help you duplicate the noise so you can figure it out. Perhaps a big, empty parking lot? Noises have to be heard to figure them out. Link to comment Share on other sites More sharing options...
