No More Hood Lift

Well I did the the Mod for the crazy Hood Lift at 65-70 mph...scary. It doesn't move at all at 75, just got done testing for about 25 miles between 65-75mph higway. What a difference now, coming back from Camp Jeep last year my Son was actually worried the hood was going to leave the Jeep. Soild now.
Easy cheap Mod, > 36" long, 1/2" (osd) black rubber hose bought at A&A Auto, black silicone & taped it over night. Piece of cake. Also removed the the spring beside the latch on hood. The air doesn't push that flimsy thin piece of rubber molding down now.

Ya no,..it might be, they might of replaced that very thin flimsy rubber molding with a heavier piece that won't collapse and let the 70 mph wind come under your hood. Just check it out & you'll no. Let me no if they changed it. I no this 1/2" hose blocks all frontal air & that's the ticket.

The fix went together well. The only thing I did different was roughing up the rubber with sand paper for a better stick. Rubbed off the goodyear writing so it blends better.

there are several remedies. the rubber tube. removing the spring. replacing the rubber latch with a solid latch. adding a piece of square tubing under the upper core suppport as another lock...

some work better on different rigs.

Another long windy drive yesterday taking my Granddaughter home,..very pleased with this, no up & down hood movement at all. Really don't have to watch it anymore.

I'm dropping the hammer on the fix this morning. Not worried....So far this is the best and cheepest fix. The new latches look cool but just too much work and money that I can spend else were. I think the square tubing didn't work out well in the end on that thread. This is the best way to go. Plus...remove the spring as well when you do this....

I think it might have been something early in 07's production.

Our black one that we got in September 06 was bad, real bad. The red one we got in September 07, I haven't noticed the hood lift issue on really.

The quick way to find out is look at the rubber molding on both & see if the newer one has a much stonger texture of rubber,.... or they went to a complete round piece instead of a flimsy thin 1/2 moon piece that the air will lay right down..

Yeah, I heard a rumor that they upgraded the rubber piece on the 08s. I would be curious if that's true.

I don't think its so much the year of the vehicle. I have an '07 and it only does it occasionally. Its not much and it is easy to mistake for road vibrations most of the time.

I have noticed that it only occurs when the wind comes from the side or from an angle.

Part of it is the rubber piece that comes stock, but I firmly believe that it is also inherent in the design of the hood period. I've talked to people with CJs, TJs and YJs, all have experienced this at one time or another.

Remember that the hood wraps down the side rather than dropping down between the fenders as on most vehicles, so air can easily get underneath it and lift it up.

I made a suggestion on another forum, that I personally haven't had the opportunity to try yet, though someone else tried it and said it worked great.

The solution? Run some weather striping along the sides to help keep the air from coming in under the sides of the hood. Once I get the bills caught up and can start doing more work on my Yeep, I'll do this myself.

All of these weather stripping approaches seem like they're doomed to failure to me. The entire underhood area is open to pressure blasts from the front through the radiator. Pressure can also enter quite freely from the bottom and the sides through the openings in the wheel wells. I see the problem all the time when I meet a big rig coming at me from the opposite direction. I feel the big pressure blast and the hood raises. I believe the pressure enters mostly through the radiator area and simply stretches the rubber bands.

I truly doubt that you can solve the problem by sealing the gaps between the hood and the rest of the body. I think the real solution lies more in replacing the rubber bands with a positive latch of some sort that holds the hood securely in place, as seen elsewhere. The modified safety latch approach would also accomplish this, though one should be careful to not eliminate the main purpose of the safety latch when modifying it.

They also sell replacements for the rubber side hood latches with beefier ones that don't stretch from the wind. That fixes it... Or if you are short on cash you can zip tie over the rubber ones to prevent them from stretching.. Just 2 more simple fixes for ya...

These are all great, but in my opinion, this ought to be a recall dea from JEEP. Obviously there is an issue. I will be duing this mod myself, but I wish Jeep would step up to this and recal for stranger latches or rubber.
