'02 745i squeaking noise at low speed..

[TomT745]

At 5-15 mph, this squeaking/squealing noise seems to be coming from the front of the vehicle. It only happens when the car is warmed up (10 min. of driving). What could this be? The local service center can't figure it out either. Could it be a brake/caliper issue? I perform regular service on the vehicle. Man do I want a 2010 750i.... anyone want to donate?

I think I'd start with checking the brakes.

Ball joints and metal shroud touching the roto are also possibilities how many miles you got on her

Possibly a caliper binding/sticking, after a journey touch the centre of the two front wheels and see if one feels hotter than the other....hot one will be the problem.

She is running strong with 150k mi.

Check the bushings, i have seen a weak subframe bushing mimic a brake squal. Is it only under braking?

[TomT745]

Actually, when I brake, the noise stops. The noise exists during acceleration and rolling.

checked the hubs? bearings still good? it's got to be something with a rotating assembly then...checked the calipers for tightness? what about pads? one wearing down or not returning when the piston is released could squeal...

Thanks for all your help... I was putting on my summer wheels/tires and discovered that one of the spokes on my winter wheels was cracked and as it turned, the broken halves were rubbing and causing the noise... thank God summer is on the way!

Glad it's sorted!
