I have and it is very hard to pin point. I have had 2-3 very mechanically inclines fellas to listen and it appears to be coming from the belt cover closest to the driver side with all the screws holding it.
I have a popping noise that kinda sounds like rocks clinkin on acceleration. The sound is coming from under the center console area between the two seats. I have an Axis 500 with 70 hours
Any help is appreciated
