Hi folks
I have a 19 Limited with 43k on the dash . When I go 70+mph on the highway, I hear a distinct high pitched or whistling sound from underneath the truck that comes and goes. When it comes, it is very noticeable. It is almost like a beeping sound, but not always beeping at the same rate. It doesn't change when I'm accelerating, but the beeps get closer together as I'm going faster. Sometimes it doesn't happen at all, even at 80mph.
A little research told me it might be something in the differential?
