Grinding noise from rear driver's side wheel/brake/suspension
When slowly taking off, I hear a metal grinding noise, it sounds like something is rubbing on the brake dust shield behind the rotor. Only at slow, slow speeds when launching and reversing. I took the wheel off to see if there is a pebble or something stuck between the shield and rotor, or wheel, or somewhere in that area but I found nothing. Any ideas? Naturally I would go to the dealer, but I recently lowered the car and don't want them blaming the suspension mod on this problem. I've dropped every one of my cars, and I doubt that's what the problem is. It was fine for a few weeks after the install, this noise is pretty recent.

mine started doing the same noise, on the rear driver side wheel, I don't know what it is, but it seems to go away at times, I haven't lowered my car, I thought maybe the exhaust was loose, but nothing, I'm taking it to the dealer, see what happens

I believe there's a TSB (or whatever BMW calls them) about the brake shields on '08 cars and some '09s, but they usually 'clicked' only with heavy cornering. If the shields are silver, they're the possible bad ones, so you might get them replaced without much fuzz. Do a search for the bulletin number, so you don't waste time while dealer looks for it.
Having said that, I'd lift the car, roll the wheel by hand, and try to duplicate it that way. You can always bend the shield a little to clear any rubbing. Since I'll never track my car, I won't bother replacing them. Plus they might not even be bad, as not all make the clicking noise. Good luck. |

It happened to me after I gave my car a wash. For the first few miles after the wash it sounded like I was lugging around a rust wagon that was falling apart. Kinda embarrassing driving an expensive car that sounds like it's falling in pieces. The noise eventually went away a few days later. My friend told me that it could have been build up of hard water (calcium) in the brake assembly that caused all the noise. Now after every wash I blow dry the wheels/brake with my leaf blower. My neighbors are staring to think I've gone nuts since I got my car. I was always a few fries short of a happy meal to begin with.

..several threads on this over the past 18 months...it is a small rock stuck between the brake rotor and shield...very common. I have 25,000 miles and it has happened 4 or 5 times randomly but then goes away...sounds like your dragging cans around??.....good luck...

I have a similar/same noise. Mine comes from the passenger rear wheel, most of the time, on very slow (in parking lot...)speed tight right hand corners. I thought it was the brake scrubbing or something to do with a differential lock or slip...The driver side will do it occasionally on tight left hand slow (parking lot...) corners. Searching for a TSB...

Yours is diff chatter, which is normal. But I've read there's a TSB on that too which calls for a different differential fluid (with more additive, I guess).
The TSB clicking noise I was referring to is just during hard cornering, and involves silver rotor covers (newer ones are black). And the 3rd potential problem, a pebble or rock wedged in the shield is not really a problem, plus it's easily remedied. OP needs to determine which of the 3 he has . |

If I had them I'd have listed them, but just remember reading about them by accident. Since I didn't have any of those problems didn't pay closer attention. Sorry. But they're somewhere on this board .

Bump for a good read. This just happened to me in my 2011 E90 and I thought my wheels were loose or something but it's definitely the brake heat shield.

SI B33 01 02 January 2009 Rear Axle Technical Service This Service Information bulletin supersedes SI B33 01 02 dated March 2008. designates changes to this revision SUBJECT Grinding Noise from the Differential during Slow Cornering MODEL E46 M3 from start of production E60 M5 from start of production E63, E64 M6 from start of production E90, E92 and E93 M3 from start of production E85, E86 with S54 from start of production SITUATION A grinding noise may be heard coming from the differential during slow cornering. This noise is best heard during tight cornering situations; for example, while parallel parking, driving in a tight circle, etc. CAUSE When the rear wheel speed differential varies during tight cornering, a slip stick effect is created on the lining and steel discs incorporated in the differential locking clutch, causing the grinding noise. This noise typically goes away as the locking clutch discs in the differential are broken in. The break-in time varies depending on driving habits; for example, tighter cornering (working the locking clutch) means that it takes less time to break in the locking clutch discs. CORRECTION If a customer complaint is verified as described above on the E46 M3; E60 M5; E63 and E64 M6; or on the E90, E92 and E93 M3 vehicles, the differential oil should be replaced with a specially formulated differential oil, BMW part number 83 22 2 282 583. PROCEDURE 1. Drainthedifferentialoil.Refertotheappropriatemodel repairinstructioninTIS: Main Group 33 / Subgroup 10 / RA 0011259. 2. Refillthedifferentialwithspecialdifferentialoilass hownintheillustrationbelow. Differential fill capacity = 1.2 liters (1.3 quarts). Remove the seal (1) between the bottle cap and U:/.../www.bmwtis.net tsb bulletins bu... 1/2 neck. Pull the filler tube (2) out of the bottle. Remove the cap (3) from the filler tube (2). Insert the filler tube into the fill hole in the differential and with the bottle positioned under the output shaft, squeeze the bottle to transfer the oil into the differential. 3. Roadtestthevehicle. With the vehicle at operating temperature, drive in tight circles (20 circles in each direction), allowing the special oil to coat the locking clutch discs. The grinding noise will decrease when the locking clutch discs are sufficiently coated. Some slight noises may still be heard after driving in tight circles. Advise the customer that it will be necessary to drive the vehicle up to 600 miles before all noises are eliminated. Note: Vehicles that have had the differential oil converted to this special oil should continue to use this oil whenever a service requiring the differential oil replacement is indicated. PARTS INFORMATION Part Number Description Qty. 83 22 2 282 583 Special differential oil kit 1 Contains 3 bottles - .5 liters (.53 quarts) each (order quantity 1 : bill out quantity 3) WARRANTY INFORMATION Covered under the terms of the BMW New Vehicle Limited Warranty.

Same issue here fellas. I purchased a nice used 2012 E92 last weekend. This had me so perplexed, I went for a quick spin last night in the rain to test out to auto lights, and auto wipers... low and behold a grinding noise at very slow speeds, I stopped, broke out the flashlight and was laying in the rain in the driveway, didnt even pull it into the garage. Can you say a bit neurotic? But felt good to be back in the "I love my car" game, as my previous DD was lame.
I am hoping it is a rock.. sounded like dragging tin cans or something metalic rubbing. I plan to take the wheel off tonight and have a look. I will also note the color of the brake shield. Dan |
