OK first of all ive lookied for something about it on the search posts, could not find anything. so here it goes./.
ive noticed that when im driving the car, the faster i go the launder this noise gets,
it comes from the rear of the car, i haqve a rebuilt suspension and the wheels are brand new..
what is raod noise suppose to sound like? what is the sound of a worn cv joint? all my fluids are 6 months old, and are all synthetic., so i dont think is diferential..
Ill try to record the noise and will post here tomorrow most likely.
but in the mean time, can someone give an idea of how this sounds like?

do you think it could be a wheel bearing? does it get louder the faster you go? then all of a sudden near a certain speed it goes away?
also check your tires, if you lowered your car, maybe its your tires.
well the shock mounts i did replace them so i took that out of consideration..
the wheel bearings.. the noise does not go away the faster you go, it just increased,, but it does not go away..
and how does a wheel bearing failing sounds?
also my tires are brand new, im using yokohama on all four, how can the tires affect it.. if needed, ill send the tyre number specs, dont remenber of my head.

actually you could be right,, because i have a new set of tyres, but my rims where purchased for aorund 300 , five rims got them with a buy at ebay that lived closed by, i know they where not perfect, and so before putting them on the car i took them to a guy to raound them off. and it did help.. but off course they wont be nicely round as new ones...
[attachmentid=17696]ok i got the wheel specs on my car, i have a set of yokohama A550V with some 10k. so they are good.
the rims are BMW set pictured below.
the tire size is P225/50R16 91V
So i dont know is this contributes..
also ill put the sound clip tomorrow i have to record it.
also out of curiosity, how does a failed CV joint sounds like.. I've inspected the rubber boots its all good. but do they make any noise.?
And the last thing, if the differantial has low oil, what does it saound like...?
i've replaced my differential oil its been 6 months with syntetic, but i know its leaking very little since the exterior part around the seal is wet, but not dripping, one of those very low leaks. anyway just wondering how that sounds..
have a good one, thnaks for the help, and ill have the sound clip tomorrow.

hey man here is an audio clip of the noise.. the click noises you hear on the sound clip are the microfone hitting the seats.. but pay attention to the main noise..
notice it keeps change its frequency as you go faster..
pretty much is that the faster you go, the more faster this noise occurs..
anyway if someone could let me knoew what is this??? ive checked suspension i dont seee anything loose.. and is all new..
and wehn driving o dont feel vibration on the center of the car, so i dont think it has something to do with the drivesaft, just the noise coming from the rear..
honestly is sounds like a problem with one of your tires. have you gotten them checked out? if not get a good look at the wheel bearing. if the noise changes exactly with the speed, than its (IMO) probably gonna be related to the wheel or surrounding parts.
it better to replace both rear ones at the same time?
also does someone know where can i get the bearing tool, rent it.. i really dont want to take the whole trailing arm out..
just one thing,, when bearings go bad, dont they make a metal screeching noise???
just wondering, thanks everyone///
please let me know...
damm it, im so pissed if its the bearings...
have a good one.
the rear bearings truly are a PAIN IN THE ASS!!!!!!! its always better to do both....no they dont have to make the screaching noise, and i have no clue about the tool rental, but u will need a 32mm 12 point socket, an air wrench, and a little more than a clue when it comes to wrenching.
for most, i'd recommend a good shop, unnless u can handle a headache.
good luck.

then best of luck to ya! its doable, its just a pain......i will however recommend that you loosen the axle shaft bolts going into the rear diff BEFORE you get her off the ground. otherwise its just gonna spin around when u try to loosed er up. they are the 6 point star nuts....i think 10 or 12 mm.
the rear most muffler section has to drop....
sooo does the rear swaybar link.......thak just the upper most left bolt off. the one that sticks out of the top or the trailing arm.(i believe its the easiest.)
CLEAN INSIDE THE HUB VERY WELL. USE NO GREASE!!!!!! ITS THE ENEMY!!!!
hold the back inner part of the bearing when ur putting everything in.....they are sometimes known to pop out when using the extreme forces to get everything in.
lastly....this is one of those MUSCLE IT IN type of jobs. Eat your spinach, wheaties, or whatever gets you strong and don't be a pussy about beating it in there. it takes ALOT of force to press the bearing in and get the old one off the hub. i will recommend a torch to help get the old bearing piece off the hub.
let us know when u hit and snags. and happy wrenching.
have you swapped the front and rear tires to see if the noise moves? If so, it's the tires/wheels...if not, you 've eliminated the noise coming from the tires.
