Rumble in the Jungle
 
My '98 328i is making a rumble/grinding noise when I drive it. The noise is persistent under acceleration/deceleration and is prominent from 15 mph to 80, the speed at which I first noticed it. I have searched and found several possible explanations such as the driveshaft carrier bearing or a wheel bearing, but I'm not sure how to tell which one it might be. When the car makes the noise, it actually vibrates the car a bit and it feels centralized, leading me to believe it is NOT a wheel bearing, but I can't be sure without checking the bearings. I'm not afraid to work on my car but I would like some tips as to what to look for and how to eliminate what the problem is not. Thanks so much for the help guys and gals. :)

Anyone? Any tips or ideas?

Jack up the car and turn the wheels by hand. Should be no trouble finding bad wheel bearing. Also a good time to check the other stuff you mentioned.

when you are driving and you turn the wheel back and forth a bit, or go into a turn, listen to the noise. If the pitch changes, its a wheel bearing (mine is doing this now, going in next week to fix) if not, probably the carrier

K. I've jacked the car up and turned both wheels. Nothing. They turn rather freely (the brake hisses but, based on my previous experiences, that is normal.) and there is no binding. I am also assuming that turning the wheels by hand will create enough pressure to make the bearings bind if they are bad right? As far as the carrier goes, is it toward the front of the car? Since this is the first german car I have fooled with, will removing the driveshaft require any thing above and beyond loosening it and dropping it to access the carrier? Thanks so much again for the replies so far! :thumbup:
