Different rear axle, so no out back. in front yes you could, however i am unsure of where the break is for the ratios. Doesn't a PW come with 4.56 gears? If so will the PW locker/carrier accomodate a 4.10 or 3.73? Maybe, maybe not. The PW lockers are not designed to accomodate the torque the CTD can throw at them. Besides you'd prob want to look for a 05-08 PW front and rear end. I am not sure what if any changes they made to the axles when the PW jumped to the 4th gen bodystyle.
Perhaps someone in the know can chime in.
Either way, I'd just go ARB.
