If you own a Wrangler JK you might have experienced something very unsettling while driving on a freeway. When you go over 60 MPH, you can’t help but notice the hood jumping up and down so violently you think at any minute its going to rip the latches off and come flying up at your windshield. Not everyone notices it and some people simply ignore it. I was ignoring it myself for over three years, even though it always seems to scare the crap out of me! I know that the chances that both latches fail and the secondary, metal latch in the front fails also at the same time are slim, but it’s just a distraction that I don’t need while I’m driving my “brick on wheels”. It is funny though how my passengers react to it when I point it out to them…
Finally after three years of driving my jeep, the passenger that I’m in a relationship with, asked me to do something about it so I did.
The reason behind this flutter is the fact that the stock hood latches utilize a weak and stretch-prone rubber that allows the hood to lift and flutter at speed. The rubber is very soft! You can actually pull on your locked hood, grabbing it right under the latch and see it lift slightly. That is not a good sign!
The solution to this problem is to make sure your hood closes tighter and doesn’t lift when the gust of wind hits it.
