Where did you download the instructions from? I can only find an instruction sheet for a grand cherokee with a screw in tow hook (bj73sy). The bar i bought is for my 11-13 with 2 tow hooks. It bolts up okay, just looks like it should have something to support it vertically to take the weight of the mounting bolts.
The photo I've attached is the passenger mount from underneath. There is no vertical part to this bracket. Is this what yours looks like?
