BMW howling sound from the rear end.

You sure it’s not a wheel bearing?

Sure hope the change in diff corrects the noise!! Hate to think I’m going to all this work and still not fixed I’m a graduate of Utube University so I’m tackling the job myself!! Got a salvage diff for $499

I've got a woo woo sound sometimes that increases with speed, like when driving past roadside posts/fencing. My wife says she can't hear it but I can. Since I had my new rear tyres, they are Goodyear asymmetric 6 so can't be them surely, hoping it's nothing more than the hand brake pads sticking a bit. This thread has now got me worried though :thumbsdown: If it is bad at least I'm in the UK so help is only 3 hours drive away oke:

Is the car lowered or wide tyres rubbing on the bodywork as the rear suspension compresses on accelleration, it could be a broken spring but you would have seen that when you did the diff.

Hello,

[E85_200_3.0_6_speed_manual]

I have this weird noise https://www.youtube.com/watch?v=_GPyuxuyJRw around 20-30km/h (12-18mph) during the acceleration. Now I changed the differential, but the issue is still the same. :headbang:
I have poli bushings, but the noise was noticeable with the originals too.
Maybe every diff has this sound? Or coming from the different area? Any idea?

Hi,

Did the noise get progressively worse with time and did you establish the cause of the problem. I have a noise from the rear which I am assuming is differential but its quite loud now and there all the time at any speed and not when just under load/acceleration.

Cheers

Mine turned out to be the offside front tyre, it was deformed on the inside edge, that’s why my wife couldn’t hear it.

That's a big thing with tyre's on these, I had my rears go out of shape, sounds like a bearing.

Mine made a rhythmic thromp, thromp noise in time with the speed
