WK- Grand Cherokee (2005-2010)
My '06 G/C 3.7 v-6 just hit 219k miles. For about a year now, I have been getting a humming noise from the rear of the vehicle. It sounds like a tire hum, starts around 30mph and gets louder the faster you go. Does not change if you are on the gas or not, turning or going straight. I believe it...
