Welp, I messed up pretty bad. Changing out the shocks should have been a simple task, but sometimes life hands you lemons and sometimes you're just an idiot.
Front worked out great, the rear shock bolts were super stuck on and were pretty rusted. After an hour of fighting and getting no where, I should had stopped and looked here for assistance as I normally do. However, I told myself this is my third Grand Cherokee and am the third time of putting on new shocks so they should all be the same! WRONG!
Take it from me kiddos; when you hit a brick wall, don't try to power through the it, find a way around.
I didn't realize that it is just a single bolt going through to a welded on nut from the factory (why did they make it that way???). I thought it was a bolt going through the mount and a nut on the other side like my ZJ and WK. See where this could be going?
Because of my arrogance, I wasted a lot of time, energy, PB blaster, and Dremel discs. I opted to cut off the rear shock at the lower eyelet, and take a cut off wheel to the bolt. Which did work, kinda. Half the bolt came out and the other half did not. I ended up having to cut the factory nut off carefully. The process generated enough heat to loosen the corrosion and allowed me to unscrew the bolt.
TL;DR
I tried to hulk smash the problem instead of using my brain and feel stupid.
Luckily there's not to much harm done (besides my ego) and I bought new nuts and bolts to go through the holes.
