Documenting engine cracking sound GMC Sahara 2012 5.3 vortex. U joint falling off not assembled

In this video, I am showing that the vehicle was not properly reinstall the hardware when the new U joint was replaced you joint was replace as stated by customer from previous shop but upon further inspection, the cracking noise of the client was hearing after coming off of the highway and coming to my location. I was able to inform him and show him that the driveshaft of the vehicle was actually falling off, and the bolts had actually backed off The mounting bracket plates, and was causing the driveshaft to fall out. Service was not complete from previous shop unfortunately but it was brought to me so error
could be corrected for preventative maintenance. This is Mike with Madmikescustom. I’m located in Aurora. I will know if anybody needs any help I’m here and I’m here to help.
