Rattle Under Car

[zonk]

Hey when i bought my car it had a slight rattle sound coming from underneath.. The rattle sound would only come on if my foot wasnt on the gas it sounds like a rock hitting something or a bit of metal knocking against something. After a month of having my car I was nearrly involved in a acident which caused me mount a curb to miss this car. Lucky no cosmetic damage was done but it made a big Boom when i hit the curb..(I hit the front tyre and yer did a sorta bunny hop over it).. I pulled over to check if any damage and yer none as i said.. then i start driving and i notice after a few minutes that the rattle sound was gone.. I WAS LIKE WOOOPP WOOOP.. then just today ive hit a curb by being a fkn idiot having my seet all the way down and driving gangsta styles lol.. And now the rattle has come back to haunt me.. If anyone would be able to help me with this curb ball its doing my head in already .. makes me not want to drive my car and i love driving !!! HELP PLZZZ

Is it coming from the cat area? Sometimes the welds break inside the pipe and you get bits of metal caught in the cat that rattles like a mofo, better or worse depending on gas flow. The other option is to get it up on stands and just take a look.

Let us know how you go.

Check your exhaust hangers and your universal joint - it could be worn out.

i mounted an island once because some old man with a stupid acubra hat didnt keep his lane,,,,, I used to get a grinding sound when i put the car in reverse or when i dropped the gear without accelterating, it sounded like stone grinding..... anyway lifted it up and it was a piece of mettal that got bent and was rubbing on the rear axle, i just bent it out of the way..... cant remeber if the metal was from one of the exhaust mounts or an axle guard...

anyway it would be something simple like that

There's also plenty of exhaust shielding under the car also, it bends and wobbles pretty easily.

There used to be a rattlin noise on my r32 comin from the exhaust. I always thought that noise was a hole in the exhaust until a few days ago I took it to the mechanic and he removed the factory heat shield near the cat and now the rattlin is gone.

i took it to the mechanic the other day it was heat shield the bit on the exhaust which makes ur exhaust sound softer dno what its called i forgot.. but that was rubbing against the little turbine that spins (located dead in the middle under the car) dno what thats called lol .. But gona get it fixed and just remove that shield i think it is and get a 3 inch pipe and stick it in and chuck out the shield thingy lol... so gona be alot louder

Do you mean there was shielding rubbing on the turbo housing?

[zonk]

It was the cat converter rubbing something forgot wat it was called but it looks like a silver cylinder that turns constantly

LoL, the tailshaft? There's nothing else in that area turning that's exposed.

Good to hear it's sorted

[zonk]
