Have you or a shop even looked under the rig to see if anything is obvious? Otherwise, the possibilities are endless. Any recent work done to the rig? You said you are about to put it on the highway. How long have you had this noise problem?

Previous owner told me about it when I purchased, Ive looked under and haven’t seen anything out of the ordinary hanging out I tried to shake the exhaust, I’m going to try and replicate the bump when I get back to my truck, plan on having a professional look at it but wanted to find a what to fix myself

If you are going to fix yourself, you need to know first what the problem is and trying to diagnose a noise with your supplied info is a crap shoot. The info about the previous owner and that you have looked with no luck is also info that should be supplied in the first post. Frustration builds when trying to get info and it is supplied in bits and pieces. Does speed of when you hit the bump make a difference? Does turning over the bump make a difference. Does accel or decel over a bump make a difference? Etc........
