I do not have the answer for the wiper arm, however I have an answer for the wiper blade:
1. Be sure you get the right replacement wiper blade. The 2005 Jeep Cherokee has a special 14" rear wiper blade that fits the special rear arm. You can go to your dealer (which may be expensive) or you can look into 'Trico Exact Fit Rear Integral Blades' that snap right onto the special arm and look just like the factory original. They're available online.
Note that just because its a special arm, does not mean its hard to change.
Important: When buying windshield wiper blades be sure to always look up your make, model and year in the application guide book at the store
