I have a 98 TJ. I have a 500 miles trip one way next week. The wind noise is quite noticable at highway speeds from where the top meets the windshield frame. Over the last 3 years I've just dealt with it from both my jeeps. Figured I'd ask if anyone had suggestions on reducing the noise.
Put up with this for years too... then it occured to me theres a really simple way to debug it. Just needs a big roll of tape and a few hours. I used clear packing tape from staples... I'd recommend the heavy/thick stuff since it will remove easier and wont split off.
I started by taping across the where the top meets the windsheild. Then take a test drive to see if it goes away. Then kept taping more things off one at a time and taking a test drive each time.
Turns out mine was actually coming in under the wind shield at the joint that allows you to fold the wind shield down and lay it on the hood. It was even a bit of a tricky thing to tape off as you go straight across and cover the bulky hinges over with a ton of tape. I noticed the noise was reduced but still there. I overlooked a body joint between the cowel and the fender that allowed air in at higher interstate speeds. It was not even a 1/8" across/deep, but it was sufficient to cause the noise.
So now at least I have a quite jeep even if its duct tape repair man status... and I know which seal needs fixing, so its just off to find time to fix it.
When I got a pelican case it came with a big block of foam to cut out whatever you wanted to keep in it. Anyway, It had a lot of foam padding left over...(it tears apart pretty easy) and I put it in between the top bar that contact with the soft top.
I do not think Jeeps were made to be quiet. At freeway speeds there is going to be wind noise. The aerodynamics alone create wind noise, it is like driving a bill board. Like others say, turn up the radio if it is bothering.
encase jeep in a bubble. of packing tape. hahaha. I'm sorry, but I'd rather have wind noise than drive around with my jeep with tape all over the place.
Its just a debugging aid to see which seal is not tight. Not like you're supposed to leave it there forever.
In a hard top jeep, you should be able to easily make a phone call and listen to the radio, so if you cant do either easily, theres a seal thats letting air in. And there so damn many seals that all sound the same comming over from the passenger side, its hard to tell which one it is. So a little tape and a few hours and you know which one you have to replace... hopefully with a thicker one that holds up better than the crap jeep put on these from the factory.
I regularly change out tops on my jeep. One thing that I do when I put my hard top on is that I put one or two strips of weather striping between the frame of the windshield and the top. Doing this drastically reduces the wind noise! Hope it helps!
get some weather stripping or foam stripping, caulk stripping, whatever. Pull the top, line the top edge of the windshield frame with the weather strip then set the top back on and screw 'er down. Make sure it is thick enough weather stripping to squish a little when the top goes on. This will seal it all up nice and tight.
Mines a soft top so the radio on 30 ( out of a possible 60) makes the noise go away And since I refuse to use a phone while driving I can't tell you what to do for the phone, except set your voice mail up to say, " I'm driving, leave a message"
I am finally on board with obama's hope and change thing. I now HOPE that when its all over I have at least a little CHANGE left.
1. Take your hardtop off. Scrape off any old foam/gasket/sealer that might be left over between the hard top and the body and windshield. Clean the surfaces that will meet when you put the top back on.
2. Replace with new sealer. They sell custom made stuff, but you can use the same stuff they use for campers. Put a new strip across the top of the windshield, across the body tub where the top will sit. I'd recommend against Pelican foam (good idea though), or any messy caulk type suggestions.
3. While it's off, make sure the gasket around your windshield is still good (like Atuel suggests). The part where your whole windshield folds down - that wears out, and can be replaced.
