So why do the mounts come loose in the first place? Isn't there a set screw securing them? Well actually the mounts are held to the truck with a soft rubber like epoxy that boosted applies during assembly. The set screw is only there to align and hold the mount wile the epoxy dries. If you try to tighten the screw once the mount is loose, it will only dig into the aluminum truck and continue to rattle. If you are unfamiliar with the sound it makes when it is loose, here is a video of mine when the first mount came loose:

Lets get started! You'll need a socket wrench or skate tool, a 1/8 Allen key, q-tips, JB weld two part epoxy, something to mix on or in and some paper towels.
Start by taking the wheel and pulley assembly off along with the little rubber o rings.
Next loosen the set screw located on the rear of the mount.
Wiggle off the motor mount being careful not to tug on the wires.
Mix the epoxy.
Apply epoxy generously to truck where the mount goes.
Carefully slide mount back on while holding wires so they don't touch the wet epoxy.
Wipe excess.
Put wheel back on and don't forget the rubber o rings. Make sure belt is properly centered and tighten set screw. Double check the alignment, do final clean ups and let cure for at least 10 hours. (15-24 is optimal)
That's it! See not so bad. Sure beats waiting two weeks for boosted to do basically the same thing!
