Full Throttle Gaming XP

Hello, I've had the same issue as the OP. Has anyone figured out this issue?

So I have a 2016 GMC Sierra 1500 4x4 SLT 5.3, 8 speed. I hit a pothole yesterday and shortly there after I had a "Service 4WD" message come on. I drove home, roughly 2 blocks, went to turn in my driveway and it was grinding/howling while turning. Only did it while turning. Definitely binding in the front diff. It has 2WD, Auto(AWD), 4WH, and 4WL. I turn the dial and it doesn't change to any other selection. What I've done so far: CVT joints inspected for damage, same with the front suspension, balls joints, tie rods, etc. Doesn't seem to have any damage. CVT joints loosened but haven't been removed yet. I checked fuses just in case, nothing wrong there. Didn't throw any code, and none pending. I know it could be a few things: Transfer case Short driveshaft stuck in differential Broken CVT (still have to check) Front Differential broke somewhere Transfer Case Emulator motor broke Am I missing else I can check? No visual outside damage to anything anywhere. I don't want to have to rebuild the front diff. Other question: If I unplug the transfer case and disconnect the drive shaft to the front diff and maybe even remove both CVT joints, even though it's still in AWD, could I still temporarily drive my truck without damaging the transfer case/tranmission. Or can I just remove the driveshaft from the T-case to the front diff and drive that way? Anyone have any suggestions?

So I have a 2008 Silverado 1500 LT 5.3 Extended Cab Texas Edition. I've had the truck going on 8 years now, but the trim has started to get loose. I've replaced body clips but some of the plastic has begun to break. I've searched junk yards, and auto lots with no luck to replacement. I tried GMdirect for the trim but still unable to find interior trim for this truck. It shakes and rattles over bumps like crazy, back door trim fell off. I've used foam to help quiet the rattling but if the trim doesn't stay on, there's no point. Might be from the back doors rattling (cannot figure that out either). Does anyone have a website link other than GMdirect for where I can find the interior trim replacement? Thank you!
