Hum @ 80mph - BMW Forum

Well I just baught a 93 325i with aprrox 160k miles on her and while driving home I noticed at about 80mph I hear a hummmm type sound.. It makes this noise with or without depressing the gas peddle. Think this is comming from the drivers side (left front)but can't really tell while driving Any ideas?

Um thats funny that no body has commented this yet. Well I work on these cars all day long and it is definitely your wheel bearing. hands down, Cheers

I was gonna say wheel bearing also.

sounds like a tire problem

If it's a wheel bearing, the noise will change when you take a corner. It will get louder when you load the side with the bad bearing.

loading the drivers side like when Im in the car?

Now are these berrings re-packable? or should I just buy 'em while Ive got the old one out?

I thaught tires too of course since I just baught the car last week but in the glove conp't. I noticed the reciept ..... new and balanced less than 4k miles ago. Ill check the berring this weekend when I change the clutch.. Thanks for the replies!!!!

If not the bearing..and ur not sure its from the front it may be your differential. They tend to hum at higher speeds when the fluid needs to be changed.

sorry to dissapoint you

just kiddin, it's the bearing
