2018 with 35k on it. I suddenly got this humming noise today. It is speed dependent. I suspected tires at first but weaving back and forth makes no difference in the sound. I can pull the clutch in and it makes no difference either. Below about 30 mph I cant hear it. It kinda sounds like a bearing. I used a temp gun and shot my drive pulley and front wheel bearings... 134 degrees. Anyone have a clue what could be generating this humming?
