Ok the title might throw some people off, I’ve been looking for this noise since June, a rattle and pop over bumps and turns. I have replaced everything in the front end besides my rack and tie rod ends. I know that they are ok. I found a way to replicate it by shaking the truck back and forth. I layed under it while a buddy shook the truck, and I tracked the noise and it’s coming from the motor mount area (driver side) and a bolt is loose to the touch. The mounts are in good condition. Only a year old. Could this be my problem all along? Video here! Sorry for how short it is but I labeled the noise
