keeper10,

It could be a coincidence but I would rather think that the two mods you did on the front end altered the air flow enough to mitigate the wind noise.

Congratulations!

Thanks ^

Well... Did not consider the lift itself but...

It was pretty loud. Never really gave it much thought though.

Noticed yesterday. Figured I drive another day before I posted. Drive to work was silent. I did nothing else. Top or doors stayed put. Just thought it was interesting and wanted to see if anybody else experienced the same removing the AD.

And JB... It would whistle at any speed. Increased as I went faster. Assuming it was coming from the top of the windshield.

Sometimes the airflow "whistles" can also depend on whether you've got your A/C--fan on/w windows closed, or heater/fan going/w windows shut--(positive internal airpressure) !

It's a jungle out there !

I have a windshield whistle that absolutely is driving me crazy. Everthing is pretty good with the soft top raised but it sounds like a bird tweeting when I flip the sunrider back. I noticed the leading edge of the rubber seal on the top of the windshielf frame sits a little high compared to the other new Jeeps on the lot. When I put a piece of tape from the metal frame to the rubber the whistle is reduced but doesn't totally go away.

I bought a Wade windshield air deflector and it reduces the noise even more but still doesn't completely get rid of it. But the Wade unit is basicially useless because it makes an absolutely huge buffeting sound on the soft top when I close the top. Then I bought a Rampage metal windshield header that's meant to be used with their Bikini top and it was about the same as the air deflector - some noise still present.

I've tried taping over the gap around the windshield, removing the antenna, removing the wiper blades and arms and installing round rubber seals (used on screen doors) between the gap and the frame around the windshield. I can tell you the air flow is very sensitive to minor changes because the whole soft top started shuddering and popping when the rubber seals I attempted got a little loose.

This whole thing has gotten me pretty OCD about it. It's too the point I can't enjoy the new Jeep because all I think about is the whistle when I'm driving. It's OK with the top up but I bought the Jeep for the open roof driving.

Here are a few pics of my vairous attempts and getting rid of this.

Holy cow... Really bothers you huh?

I drove a Tj for 10+ years that made every noise possible. Whistles/rattles/pops / etc.

I have seen write-ups for fixing the ever so common windshield whistle. adjusting the doors may quiet it down also.
But never tried anything to fix it... I really did not care much to be honest.

It surprised me when I realized it was gone. I am sure the noise was still there after the lift. AD was removed Saturday.

Remove it and see what happens. Worthless piece of plastic anyhow.

This may not be the source of your whistle, but mine was fixed by running a bead of silicone around the windshield.

I fiured I'd have noises with the jeep whether I was sporting the hard top or soft top.
I haven't tried the soft top yet...just got the jeep this winter. But, I have major wind noise fro the windshield /hard top area.
I found that if I pull down on the center of the roof edge the whistling is less. However there is no latch to pull down this section of the hard top. I also have wind noise in the uper corners. This I figure must be the seals. The two corner (L/side and R/side) of the forward edge of the hard top cannot be adjusted for a tighter fit.

I was wondering is there a mod that secures / clamps the center of the hardtop available? I'd hate to have to drill holes in the roof but may have to. There is a bracket on the windshield for a strap when securing the W/S when in the laid down position.

help or suggestions is welcome.

Caulk bead window whistle fix

Hey Cruise Missile.

I agree with putting a bead around the windshield to fill in the gap. I have been through 3 windshields so far on my 2009 Sahara from rock attacks. The most recent windshield I had replaced gave me fits. The gap around the windshield was equally spaced just like the first 2 were, but it started whistling on my way home from getting it replaced. Man, the disappointment you feel after spending $275 on a new windshield and it sounds like Tweety Bird is in your Jeep.

To anyone that has the dreaded whistle, before you go throwing some caulk around, , tape up the windshield gap first and go for a drive. Like Dale-K shows in a few posts back. Process of elimination is in effect here. If it doesn't whistle with the tape on, remove the tape and caulk the gap. Helps if your Jeep is black, that way you can use black caulking. I imagine clear would look okay too. The windshield gap (approx 4mm or so) around the windshield creates air turbulence, hence causing the dreaded whistle with the windshield. Filling that gap has worked for me. I am sure this method has been talked about prior as a fix.

Just a reminder, this is only one of the areas owners have had issues with the dreaded whistle. Process of elimination should be used to pinpoint the whistle.
I wish you all good luck.
