I have a 23 Raptor, 6500 miles are on it. I recently noticed that when accelerating from a stop you can hear a clicking/ticking noise coming from the rear of the truck. I only hear with the windows down, especially when next to other vehicles or walls where you can hear sounds echo. Sounds like this clicking is coming from the rear axle or driveshaft. You can hear a series of clicks when accelerating from a stop. I thought it was rocks at first but it’s definitely mechanical. You can also hear the clicking noise when shifting from park to drive or drive to reverse. All coming from the rear end. Any one else have this or know what this could be? Thanks.
