After making a few tight turns in a trail, I started to hear a popping noise when making turns, got out to have a look and notice this small arm is bent not sure what the part is called to order a new one? Anyone know ?

 

Picture looks like Sway bar.
Might want to check junk yards for a used replacement.

Is there a way just to replace that smaller post that's bent coming up? Looks like it just bolts Onto the main bar

 

That is your front sway bar and the small shafts that connect to it are your swaybar endlinks. If just the endlink is bent, those are easily replacable either with stock replacements, quick disconnect models, or adjutsable length. All Jeep aftermarket vendors carry swaybar endlinks.
