It sounds like a high frequence virbration (similar to revs), the pitch increases with the speed of the car. Noticable (above other noise) at about 35mph, then gets louder and higher as speed increases. Dipping the clutch, accelerating or cruising has no effect on the noise, so I'm guessing its coming off the wheels/suspension? It sounds like its coming from the rear of the car. I dropped the tire pressure for the recent icy/wet weather., but putting it back up also made no difference. I did do about 1200 miles two weeks ago and 900 miles last week. And about half of that was in wet weather on gritted motorways. I'm guessing something is badly worn as a result. 1994 BMW 320i coupe.

Jacking the back up and spinning the wheels by hand would be a decent place to start. Guest   #3   12-03-2005, 06:12 PM Josh Assing Junior Member   Join Date: Nov 2005 Posts: 51 What's this noise? I'd check your drive shaft balance if you have a balance AND noise issue... just a guess tho. definately check the oil levels (tranny, diff) and jack the car up and spin both rear tires to be sure the bearings spin freely & there's no play..

My guess is that a wheel bearing is going/gone out. Have it checked out before it becomes a catastrophic failure and leaves you stranded.

The Inspection II light also came on , so I guess I'll have to grease up . I have to do about 20 town miles on Sunday. Hopefully it will last me until Monday !

Is your car a manual? Does it make the same noise if you are not in gear and just rolling along in neutral? (note: you have to actually be in neutral - disengaging the clutch just disconnects the transmission from the engine - if you are still in gear with the clutch disengaged, you will still hear the whine) My car (2004 E46 318i manual) has a transmission whine, particularly in the lower gears - it is normal and nothing to worry about. If this has just appeared then it is probably not normal! Paul "Lordy" <see.reply.to@lordyorguk.invalid> wrote in message newsan.2005.12.04.00.18.08.590760@lordyorguk.inv alid...

Is it more noticeable on sharp corners, especially in reverse? R. Mark Clayton View Public Profile Find all posts by R. Mark Clayton Add R.
