Very easy.... Did mine last weekend. I reused the bumper fasteners in the rear, They come out real easy, Had to cut the heads off the plastic rivits in the wheel wells, No big thing. Bought replacement clips at autozone.
I'd recomend a impact wrench to remove the bolts.
Spray a little penitrating oil into the 2 rear bolt holes to clean out the dirt. Mine were really bad.
I Set the hitch up on a crate underneith the jeep. My wife lifted one side while i put the front bolt in the other. Just worked my way to the back.
