rear end is making a popping sound that almost resembles the noise a ping pong ball makes but its only during slow acceleration. theres 2 videos attached to this so hopefully someone can provide some advice because i have no idea where the noise is coming from

 

Sounds are always so hard to diagnose over the internet, even with a video. Stock diff and axles? Are you able to jack it up and take a look at things?

 

Check to see if the pinion nut is loose
