It only happens on the highway above 60mph. Not a rotational noise or a rhythmic noise that would go with a turning tire p.. It is definitely a Random noise like pebbles hitting the fender wells. Had my wife ride back there with the seat down. She said she heard it on both sides under the car in the fender wells. It is faint but definitely audible.

I check the lug nuts every time before autocross. Also it isn’t the clicking noise from the wheels under load in a turn. I have already fixed that and know it’s volume well.

I can check the axle bolts. Seems kind of like a long shot but I guess you never know.

What bolts would those be and what are their torque spec?
