Is it a regular rotational noise that's happening at the same rate as the wheel is rotating (ie.... bloody fast at 40-60 mph!!
) or is it a lesser/slower frequency noise?? Maybe something that fluctuates up & down in volume &/or frequency even at a steady speed?? Or is it just an occasional chirping noise that could be something like a brake pad grabbing every now & then??
Need a bit more detail about the noise, what it sounds like, when it happens, how it varies with speed/anything else, or even
IF it ever varies to really help much more.... sorry!
