Bringing this thread back to life.
I have a 2020 Jeep Grand Cherokee High Altitude and am in the process of making this vehicle ski rack worthy.
Starting with the rails, I have ordered and installed the rails that can accept cross rails:
Add functionality at the same time with a set of genuine factory Mopar neutral grey roof side rails for your Grand Cherokee.www.justforjeeps.com
After the install did a quick test lap and they were silent, they feel solid and the neutral gray matches my vehicle perfectly. So step one complete, on to the rails.
Installed the rails and to be honest they were super simple. Clearly marked which direction to go, allen wrench even included. Took about 15-20 minutes to install and I placed them as far apart as possible. Here is the product:

Took a quick test lap and these things are whistling and making so much noise it isn't even funny. They are much louder than the crossrails+empty ski clip on my previous 2014 Cherokee and any other car I have been in with a system installed. The noise starts in at 20 and just continues to get worse. After reading through this thread there is some conflicting info and this problem is certainly still there.
This thread claims to make the thick part face forward, like an airplane wing...so it looks to be just like that, but not such luck. Here is the second trail where I moved the front bar back several inches:

The next step is I am going to reverse the front one and move it back up. Will report back but wondering what it is I am missing. This cannot be how people are actually driving around day to day.
That is sad to hear. I have closed that small gap in the picture. Took the photo before I noticed it. No change :/I’ve installed the bright lines cross blades purchased from amazon and they create zero noise at any speed. My cousin purchased the mopar cross blades which I installed and they began to whistle starting at about 25mph. I then removed my cross blades and installed them on his GC and again zero noise from the bright lines product. I measured and triple checked everything to make sure all was even and flush but alas could not silence the mopar blades.
-I think I see a small gap between where the blade rests on top of the mounting bracket in the photo above. I made sure that gap was not there when installing the mopar blades on my cousins GC but they still made noise. I hope you figure it out.
Yea the Rubber strips are fully seated.Are the rubber strips on top flush or do they fold up along the edges anywhere? I don’t know if such a small thing can be the issue, just tossing that out there.
