New Member - Two Problems

Hello, about two months ago I bought my first ///M car and second BMW and E39. I have been lurking on this board way before I got my M5 just to learn about them.

But now I have two problems, an annoying whine and squeaky brakes.

The whine: It is audible at anything above about 30mph with no throttle load (I have a muffler delete so the exhaust drowns it out), and becomes much louder at 45+mph. It is a "wooo" sound when off the throttle and a continuous "whoop" sound when on the throttle. Both sound almost like loud tire noise but a bit more high pitched. The noise seems to permeate through the transmission/driveshaft tunnel and I have had passengers say they can hear it more when sitting in the rear. Whether the clutch is in or out has no effect either. I also just replaced the transmission fluid with Redline and the differential fluid with Redline 75W-140 about 500 miles ago (the car has 101,400 miles on it by the way). From what I have read it could be the center support bearing or the differential, maybe even transmission bearings, but I would like the have more specific opinions based off my description because the noise doesn't match up with the ticking and metal-on-metal sounds people have described the CSB as, and the diff only whining with throttle application. And I would hate the spend my time and money replacing something that isn't the problem.

The brakes: my front brakes squeak at low speeds, and screech horribly loud when I am turning with a bit of brake pressure. I haven't found much or potential solutions on this: add anti-squeal compound and bed the brakes, both of which I have done to no avail. The pads are pretty new and the rotors are in good condition. Unfortunately I don't know enough about brakes to have any idea what to do next.

Any help on these issues will be greatly appreciated as they are driving me crazy.

I'm in the same boat

That's funny. I just bought my first M and second bmw about 3 months ago and have exactly same your issues plus some more little things here and there. I took it to the dealer for inspection and found nothing. I changed transmission mounts and fluid. Changed rear end bushing and fluid and still the same. Break pads looks new and good rotors and make exact noise like yours specially after driving hard when I pull in to my driveway slowly and slightly braking it will squeak. I guess all these little things is normal for an old high performance car. As for brakes I guess rebuilding calibers and flushing system will fix all noises. Good luck

What kind of brake pads are you both using? Squealing brakes shouldn't necessarily be a problem other than annoying.

Subscribed.

I recently purchased my car with 103k and have the same noise from what sounds like the differential. Mine is only apparent at 43+ mph. I've also changed the diff fluid to no avail. I can clearly hear mine over the dinan exhaust. Noise mostly goes away when I take my foot off the gas.

It's very difficult to comment based on noise descriptions like wooo and whoop. Sound clips would be a big help.

sikesrr: I honestly don't know the brand of brake pad that's on the car right now, I didn't check when I took the off last. And its not just annoying, it is so loud it gives me a headache.

68FB: Sorry, I'm not very good with descriptions. I'll try to post some sound clips soon, although because of the nature of the sound, I'm not sure how audible it would be.

From my experience, stock pads do not squeal, they're just dusty, track pads screech like a MOFO when cold but stops on a dime. You win some you lose some.

Would anti squeal compound on the brake pistons / pad ears help the squeal?

I'm about to try that as I've got some squeal too (not sure if it's from front or rear). I've got Stoptech 4 pistons up front, and the pins rattle like crazy over bumps so I'm going to try to bend them a bit to keep some tension on them.

Drivetrain noise, I agree a sound clip would be good, but I know how subtle some of these noises can be to try to capture... Good luck with it - and Merry Christmas! (I've just snuck onto the board on Christmas morning while no one's looking!).

I have the same constant high pitched whine. Either the Center Bearing or the in the rear CV/Differential.

What differential oil are you running? My 540i has 175K miles and I've not had the same whine (older driveshaft, older differential)...

I'd put in Redline 75-90 but now am thinking of swapping in the 75-140 (both for LS applications).

bimmerule: They might be track pads. When I get them really hot they stop squeaking, and they bring the beast to a standstill like it's nothing.

M5 Sydney: The backs of the pads are absolutely coated in anti-squeal compound. And merry Christmas to you as well.

ME_264: I put Redline 75W-140 in the diff that I bought from Turner Motorsports.
