Hmm, have you done a search to try and see if others have had the same issue? Also if your IWE'S are engaging partially in 2 wheel drive and then engaging all the way when you move to 4 wheel drive then it will make a grinding noise when in 2 wheel drive and not in 4 wheel drive. If that's the case it would be a vacuum issue. Check all the lines from the hubs to the engine bay for cracks or breaks.Sent from my SM-G930T using Tapatalk
