Help! Fast Clicking Type Noise When Accelerating only (coming from rear of truck)
 

Hello everyone, first post here. I just picked up my truck from the dealership (this noise was happening before I went but they couldn't replicate it which means they didn't bother test driving it). The repairs were passenger front tire wheel bearing/spindle replacement, rear axle seals, sway bar and oil change. This noise has been going on for about a month or two now. Basically if I over accelerate at any speed the noise starts and gets worse the more I accelerate. When I'm at idle or letting off the gas the noise instantly goes away (as far as I can tell). With the windows up I can hear the noise and it seems to be coming from behind more towards the rear. At first I thought it might have been the rattling of my tool box not being shut all the way (wasn't the case lol). It's like a clicking/tapping noise (more of a loud clicking that gets worse when I over accelerate), it stops when I left off the gas. This morning when I got to work I put it in park and rev'd really good but couldn't hear it so only when im driving. Has anyone experienced this?

vehicle : 2010 ford ranger XLT with 91k miles

After some youtube research this is the only video I could find that could replicate the noise
