My guess is that you're mixing 2wd and 4wd parts. You'll need to better explain what you're trying to do before anyone can offer some real help.

From all the previous discussions on the 10-bolt axle, I've read, it's usually suggested to upgrade to a 14-bolt semi-floating axle.

Make, model, year, yes it makes difference. Twenty feet away they all look the same. Open the doors and hood there all different.
