2015 silverado. This sound randomly comes and goes while driving not while idling.. smooth pavement or not doesn’t mater, front end is solid no movement in any ball joints or tie rods. Cvs are solid! Uvs are as well! What is it!!! No movement in the steering wheel when it happens!!!
Happens when the accelerator is slightly pressed, when released and truck is slowing from a low speed there seems to be a click the as the peddle is slightly pressed the knocking returns..
I have a short video that i can text or email, this page won't allow me to upload,, Thx
