Please excuse my ignorance when it comes to rear suspensions. I am not a mechanical person whatsoever so I was hoping that this clue I am about to give may help someone help me. I know that there is not much to the rear suspension in these trucks so I am confident that someone will be able to provide some guidance here.
I am still experiencing the clunking noise. I had my family's mechanic tighten up the U-Bolts on both sides of the rear axel and it did not fix the issue. The following day I went to get my first car wash since buying the truck and the noise was almost completely eliminated following the wash. As I expected, the noise returned louder and louder as the suspension continued to dry off. That said, I am inclined to believe that this is a lubrication issue. Please let me know if anyone needs some more context here and I will try to help out. Extremely annoying that this happened to me on mile 100 on the odometer.
