Hey everyone, I’m sure this has been asked before but I’m having a hard time finding out where I should begin. Just today, I started hearing a scraping/grinding noise coming from underneath my truck while driving. It would only sometimes happen while I was cruising along, light on throttle. I found that I can make it really loud if I was on the break and gas at the same time(almost do a burnout). The driveshaft has no horizontal/vertical play, and the u joints look alright. I’m going to link a video I took, im hoping someone has heard this and might have some input. Unfortunately i had to make a tiktok and link it here, im not sure how to do it any other way. 07 1500 classic 4.3 2wd. Thank you!
