I have a mitsubishi challenger which has this strange noise at and above 100km/h. It’s difficult to describe, like a constant highish pitch hum, just loud enough to hear it over the stereo, sounds to me like some sort of wind noise. Sounds like it is coming from around the front passenger wheel area, maybe the passenger side engine bay/dash. The rubber splash mats between the engine bay and passenger wheel were split and flapping and I thought it may be them rubbing on the wheel but I tucked them away and it the noise was still there. Seems worse when the prevailing wind is going from right to left across the road and also when the aircon is on. If the wind is gusty the noise starts and stops with the wind gusts. It’s starts at about 100 km/h and gets worse the faster you go, pretty
well constant at 120.
It’s been there for a while intermittently but we went away on the long weekend and it was worse and quite annoying.
An ideas??
Thanks in advance.
Cookie.

Hi Cookie, I have 91 tRITON S/C & HAVE AT TIMES BEEN MYSTIFIED BY STRANGE
brrrringgg sound & found it to be slight misalignment of front wheels.
If they toe out you may get a singing/scrubbing sound from the front until corrected.
Run your hand slowly around tread to see if there are any lips on the edges of the lugs. Probably worse if you are using mud terrain luggies which should be rotated often.
Hope this helps.
