I have a 2006 z71....when I make sharp turns the rear end creates drag, or friction or resistance....whatever you want to call it. When I coast thru a sharp turn, the rear differential gears bring the truck to a stop. I then have to straighten out the truck to proceed. I know its a problem with the differential. I'm familiar with the spider gears, c- clips the pin.....my question is this: What other rear ends can I swap in.....just a direct R&R.....
