Front tire is grabbing on turns, I've been told it's my front differential

It very well could be the transfer case. This can also be binding in a u joint but it needs to be inspected to be sure. Don't order any parts until a shop has diagnosed the issue. If you don't work on your own car then use this link to find a good shop near you. https://repairpal.com/repair-shops Alex

4 wheel drive is engaged - whether you want to be or not .. ALL four wheel drive vehicles exhibit this when in 4 WD on dry pavement. Have the 4x4 *vacuum switch* tested - located on top of the transfer case.
