Re: 04 suburban automatic trasfer case grinding noise
You more than Likely have Broken a Tooth off of the Main Gear Inside the Transfer Case. You will need to Remove it and Inspect the Gears Very Closely. It could require a Rebuild. Please Rate My Response! Thanks!

thats in the transfer case..did you get the linkage rods put in ok or did they bind up on reinstall..I had a suburban 4wd.. its basically the same..if its stuck in4w low..put the main transmission in neutral and work the transfer case shifter back and forth between all of its selections for a bit..these get hard to shift if they arent used much..also most of the time the vehicle needs to be rolling slowly to shift it..you will feel it shift in speeds under 5mph..good luck..
Four low is almost never used. I use it on very steep rocky or muddy trails in the woods or to pull someone out of mud or a ditch. Though some will shift standing still it is best do do this while rolling. Four high can be shifted at low speeds of 2 to about 35mph (higher also but not really good idea) Low can only be shifted between 2 to 10mph. If you find yourself stuck and unable to shift because you aren't rolling you can also turn the engine off, engage the transfer case and re-start. That avoids having the gears clashing together. Best rule is if it begins to grind, don't force it.
You say 'new' truck, 09? or new used? I have had 3 Fords, 3 w/ manual trans. case, if you go into 4x4 Low range, you must come to a complete stop before shifting the trans. case to 4x4 mode, and I always put trans (automatic) in neutral before slipping into 4x4, it engages smoothly, no grinding. 4x4 high range can be put in while moving, but I would let off the gas pedal, shift to 4x4 high range, then resume accelerating. If there is any grinding going on doing it as above, something isn't right. Check the trans. case fluid level also, to make sure that's not an issue.
