Screws back out at times. They say you should give your rig a look see, and tighten all loose screws before every run. Also check the wheel nuts. Could have been loose from the factory. Not a bad idea to get a screw kit for your rig.

It is a good idea to check your vehicle after every run for loose parts, debris, etc. I have found many loose screws this way. Better than finding it was loose during a jump or speed run.
