^^^^ Thanks for the info here & in my thread about the same problem ^^^^^
Yeah baseball cards in bicycle wheel spokes or wheel of fortune.
worse in the cold start mornings after sitting all night & chilly-er weather 20-40 degrees.
When the truck was new it wasn't doing this....
I bought it in Jan & have seen colder weather no popping
It has also happened during a 2 hour drive to visit my family at several stop lights/stop & go situations.
So the truck was warmed up.
Only at low speeds or cold at reverse .....
