went to the mechanic.. put it on the ramp.. checked for lose things.. he noticed that the propagator shaft (or is it drive shaft??) was lose..( http://www.realoem.com/bmw/showparts.do?model=AF91&mospi d=47256&prod=19891000&btnr=26_0004&hg=26&fg= 05) he advised me to either get a hold of a 2nd hand driveshaft if poss.. or get the brackets from a BMW dealer.. still though.. thanks for the feedback...

I had exactly that, went down a minor road, few
bumps, and then there was a screeching grinding sound, bit like dragging a spade up the path. Got home and found a stone stuck between the backing shield and the rear brake disc. But if you say you can feel a vibration on the handbreak, you may have hit the exhaust and pushed it up so its touching the underneath of the car, or a stone between the zorst heat shield. But with the noise disapearing when turning, points back to the front brakes. Are the brakepads low? |

Could be a stone caught between the brake disc and splasher shield. This has been mentioned before on these forums as a cause of noise from the front end. Andrew |

Hello Guys... I need some assistance with this (intermittent) issue I'm experiencing.. everytime I go to the mechanics, the noise is gone.. but when I'm nowhere near a mechanics the sound is back...very annoying... anyway some background to the problem... I'm driving through town... hit a few potholes/bumps.. and all of a sudden I get this loud grinding sound coming from the left hand side of the car.. i can feel that something is rotating(driveshaft maybe) a piece of metal is rubbing against it... the more i slow down the louder and longer the grinding sound gets.. At 30 mph the car sounds like a 1950's motorbike... at first i thought it was something rubbing against the breakdiscs.. but after checking the wheels, nothing was found/.. Are there any exposed rotating bits under the passenger side that could be grinding against some metal piece/parts? I've taken off both front wheels to see of anything was rubbing against my 15" BBS's.. but nothing.. wheels are untouched... One thing i did notice is, when I do a full right turn the noise will disappear comletely... but the more i turn to the left the noise gets louder... so I checked the front left wheel first... and one more strange thing.... when the grinding noise starts, i stop the car, reverse a few meters.. and the noise is gone until i hit some other bump or hole...etc... but than it will completely disappear for a few miles... than back again.... Also when whatever is grinding away, i can feel the vibrations in the handbreak... so im thinking it is something below the handbreak area... anyone got any ideas? I got my wishbones done last week... i though that may cure this... but the sound is back... i need help.... ... |
