NP247 to NP249 swap finished!

I finally got my Np247 to NP249 swap finished on my 2000 Jeep grand Cherokee limited Quadra drive. I will have to rebuild the front drive shaft to get 4 Wheel all time back, But I may drive it around with just the rear driveshaft for now and see if it changes any gas mileage or what it changes. I know these have been the worst updates but I can’t keep remembering to fight with jeep and recording at the same time but if you have any questions feel free to ask in the comments
