I'll start with, you're not going to be opening your cloth top with this thing installed, like the description says. Yes, you can remove the center cross bars. But, the front struts won't even allow you to begin to open the top. So, there is no way that you can open your cloth top without full removal of the roof rack.
The instructions are atrocious. Parts of the rack have been redesigned since the instructions were made. There is better labeling of parts in an Amazon package. I did manage to assemble it alone in about 2 hours. If you're able to figure out puzzles, go for it. If you get confused by your remote, forget about it.
The thing is solid. I wouldn't expect problems with the build construction. Heavy guage metal throughout.
I took it out on the freeway, and I didn't notice any considerable noise. But, let's face it, the cloth top bronco is noisy to begin with. I keep looking back thinking a rear window has opened up.
I'll keep it on for now. The way the rear cross member sticks out from the back of the Bronco makes a good place to load and unload my canoe and kayak without worrying about the cloth top. And it'll be a solid mount for roof cargo haulers on trips.
