I was able to fix the problem myself. Remove the rubber covering behind the screen. Loosen and then re- tighten the little bolts holding the screen in place (not too tight, don’t break the plastic). Keep the rubber cover off for a few days as you drive the truck and adjust bolts if needed again. Sometimes it would return and I just needed to tighten ever so slightly again. The bolts are more settled in now is my guess and I hardly ever hear the sound anymore. It’ll still come up occasionally but not often and much less pronounced.
