Not good! there is a sensor in your transfer case that senses that you are now in four wheel drive if your transfer case does not lock in it will set a code and the light will flash and default back to two wheel drive. check the fluid level in the transfer case and front differential for a sign of internal failure. that is causing the grinding sound.
It's the transfer case motor.I had the same problem and replaced it, now it works great. Part is about $100.00 ( aftermarket ) .Ifyou are going to replace yourself you will have to remove front drive shaft and remove yoke from transfer case with an impact wrench for clearance to remove transfer case motor . When you put the new transfer case motor in make sure you line up slot with grove in transfer case motor. Good Luck.
I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.
I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.
