the two link/trac-bars are for axle wrap. this is the only explorer i've seen with them. i know autofab offers them for broncos.
I would have just pushed that thing into the pool and walked away, and live the rest of life oblivious as to how that Explorer made it in there.
You know, have 2.5 kids, a "cute" house with a white picket fence, a dog... and an Explorer in the pool.
