Have a 2004 h2. Daughter was driving down the highway and font wheels started locking up. Got to her and it would not move with out noise and front driver wheel almost shuttering(assuming both but could not see the passenger wheel. Changed front bearings and checked fluids. Acts like there is something locking up in the front diff. Get to about 10 or 15 mph hear a growling from underneath and then all of a sudden both front wheels lock up. Any help would be greatly appreciated.

 

I would definitely assume the front diff or transfer case would be the culprit. Disconnect the front diff from the transfer case to isolate which one it is.
