reaching out to see if anyone else is experiencing this. At low speeds, backing in driveway, slow speed bumps or slight lateral movement I have a rattle/tapping sound from what sounds like rear of truck. Looked under and ubolts and leaf springs look tight. Only thing I can think of is the e brake cables. The cables are very loose and I can see where they are rubbing on the leaf spring. Just moving them around with my hand it’s a pretty loud tapping sound. Next step is to get a friend to move the cables around while I sit in the truck to see if it’s same sound. I’m 70% sure it’s gonna be the brake cables, problem is how do I secure them from making noise? They are loose so the play in the line allows the e brake to be applied.
