Freedom top off/Driving with the rear glass open

Driving a JK with the Freedom top off was not pleasant, too much rumble and disturbed air flow in the cabin. I opened the rear glass and it was great. I started getting a little uneasy about driving with the rear glass window open as there is no frame around the glass and though it was too much load on attachment points, etc. I decide to support the glass, but wanted a simple and inexpensive solution. I went to Home Depot, bought two, flat 1/8" thick 3/4" wide by 36" long aluminum stock (P/N 3069944710) and made two identical supports that clip or slide into the hydraulic ram lower posts and run up to each side of the glass lower rubber seal. They are held at the top by a 40" bungie cord. It seems to do the trick. Let me know what you think.

That's a cool idea (as I read the beginning, I had the same concern over stress on the mounting points), but I'm not sure it's doing anything with the bungee cord attachment. It's not attached at all to the window, so it's not taking any of the force. The window is still free to move around and bounce, it just has a limit on its range of motion.

Also a new JK owner here, with the same concern. Anybody with experience on running with the window open? lflr, how do those supports attach to the window?

Thanks

Cool idea butÖ

I always thought that running any vehicle with the rear hatch open runs the risk of exhaust fumes entering the cabin. Also it seems like a bad idea too because if the Jeep starts to bounce from road conditions there will be too much stress on the hatch itself.

Yeah, I thought about that too; leaving the window open is probably not the best idea.

I've run mine with the freedom top off, the windows down and the liftgate up. Never occurred to me that it could be an issue either from stress on the mounting points or carbon monoxide.

I would think there is enough air coming through that the carbon monoxide hazard would be nonexistent. I would think twice about it if I had the top on, all the windows up, and the liftgate open. :shrug:

I believe it is in the owners manual not to run with the tailgate glass open due to asphyxiation ....
Having freedom tops off actually creates a vacuum within the cab as air flows over the roof drawing cabin air out. Opening only the rear window will allow exhaust to be drawn in and expelled through the top. Running with all door windows open as well as the back would be safe.

I didnít pay close enough attention to the OPís post about running with the freedom panels off at the same time as the hatch being opened. Probably not much of a concern then concerning carbon monoxide.

I have my fire stick CB antenna mounted the the spare carrier. When I have the glass up and close the gate, the antenna bends and pushes up on the glass and supports it. I run like that with the windows open and doorless all the time with 0 issues. I feel it's kind of a perk of the antenna.

I do have to say that it looks kinda silly with the hatch open while driving. Seen it a couple of times and it just doesn't look right.

If you really want to do that why not just unbolt the rear glass?

I have been toying with the idea of making a quick release system to just remove the glass. I just haven't figured it out yet.

Ever since I had a Bronco that the rear glass rolled down, I love driving around with the windows open and the glass out.

Make sure the disconnect is on the inside. And definitely post a thread, I think there would be a lot of interest in something like that.
