Hey guys, im kind of new to the truck scene. I have a 99 gmc sierra z71, and my front carrier (i think its also called a carrier) is fuc*ed up. I was driving in four high and it locked up on my. Is there a special carrier that goes in the front differential or is the rear and front the same. Wat size is the front and what r some good brands that are both good and fairly inexpensive. Thanks in advance
