i hate to post another weird noise thread but all day today i been hearing some werid noise and dont no if its the diff or not.. i no that if ur diff goes bad it gets louder as you accelerate.. the noise im hearing makes it even when im not accelerating and just sitting in neutral and reving my engine in netruel.. i have a invidia v3 and its not the vibrating hanger noise.. it just came out of nowhere.. it just vibrates every here and there.. it doesnt vibrate for more then 5 seconds..and when i grabbed my exhaust it still made the noise but not as much.. i dont think its the exhaust because it never made the sound before.. i just put some new 255 tires on there so i hope they didnt mess anything up when installing the tires.. it acutally sounds like theres a rock inside my exhaust lol.. anyway to check the diff other then just noise?



also my maintence light came on tonight saying 126.. i nno i need to change the oil , i change air filter like 2 weeks ago and diff fluid about 3 weeks ago.. does the diff number (6) come on from mileage or is something wrong with my fluid.. i have 27,000 miles
