So i have a 14 rubicon now. I had a 11 Sport. Both 4 doors.
To me it seems like the 14 rides a lot better. I transferred the RK lift from the sport to this one. so wheels tires, and lift are all the same. I notice it in the front end the most. Am i crazy or is there something to this. It doesnt feel as bouncy or clunky as my 11 did. THe 44 front axle have anything to do with it

 

Maybe the plastic ball joints in your 2011 wore out? If you wheeled a lot, maybe you bent your C's a little? Speculating obviously.

The front dana 44 is really a hybrid. Has the 44 center section and axle shafts, but has the 30 tubes and c's with all the same flimsiness and plasticiness.

 

We probably need more clarification. Is the lift a puck-and-spacer lift, or did you replace the springs, shocks, and other pieces too? Also, what tires were you running before, and what are you running now?

 

I was just telling a friend I though my 09 sport (before mods) drove better then my 2013. You could just still be in the honey moon stage or what the others posted above. Anyways congrats on the new ride !
