Cracking noise in rollover bar <--(?)

Not sure whats its called, maybe sound bar? Whatever keeps me safe if I roll over! Anyway, I just bought the 2004 rubicon and on the highway when i hit a crack or pothole I hear a cracking sound right over my head. Its definitely noticeable and happens often. Is there anything up there that could be loose? It's not anything in the soft top and its not the speakers because I messed with all of that and held on to them going over bumps and it still cracked.

Thanks for any insight.

Door surrounds? Soft top frame?

I maybe way off----but having had my rollbar sound pods off on and replaced I think I may have an idea--goes with "door surrounds". There are 2 large knobs that tighten the door surrounds they are very difficult to see or turn unless top is off--maybe loose or possibly broken? If it is not in speaker sound bar/pods--this is only thing left--cept for soft top framework--sorry just thought of that part.

The smaller spreader bar that pivots could be bouncing or cracked.

Haven't had a full top on in a while.

The noise if you had to pin point it--in front of your head? behind? left? or right?

I really dont think its the soft top frame I was messing with it alot. I'll check around the doors, much appreciated. It almost sounds like its coming straight over my head. Doesn't sound like anything is falling apart, but I just bought this Jeep and its driving me nuts!

It sounds like its right over my head or behind my head. I am very inexperienced on the nooks and crannies of my jeep since I haven't had the top off yet because I just bought it. I'll try and find these knobs you're talking about. Like I said above, its kind of nerve wracking because I dont know what it is. It almost sounds like you just jumped on an old creaky bed, but with a sharper cracking sound. Thanks for your help, much appreciated. I'm new and so freaking excited to have a jeep and be a part of this forum

Might just have to pull the top off to get a good look at it. I know that sounds like a PITA but.......

someone posted on here about the lights in the sound pods being loose and making a rattling noise. pop them out put them in the right way and that may stop it. There is a certain way they should be in there, If you look at the side of the lens when you take it out there is a ling groove and 2(?) short grooves on it, just make sure they line up the right way. Worth a shot and costs nuthin

Read original post again--and wondered if it is only on the highway? and if so at what speed? Does it sound at all like a wet towel being "snapped"?

If the soft top is worn/stretched enough and it is windy enough it will "snap" similar to the wet towel sound. Only other thing I can think of that could make that noise above your head.

To check if it is top itself drive on the highway with one hand pushing up slightly you will feel the crack in the fabric when the sound happens.....if it is the top.

That's what I was thinking man. gonna be cold as hell in the northeast this weekend, but it might be a good time to get acquanited with how to do it. Is it tough to get the padding off of the frame and get back on once the top is off?

I'll give it a whirl. The more I listen to it and it does seem to be getting worse, it really sounds like the noise is associated with the bar.

Man first of all thank you for helping me to brain storm. The dealer put on a brand new best top right before I bought it and I did hear that snapping noise you were talking about, but it doesn't do that particular noise anymore now that its broken in.

The noise that's really bothering me now is definitely METAL on METAL. And it does happen at all speeds, but it's harder for me to miss obsticals in the road going at high speeds on the highway. Going over a speed bump or turning sharply will make it do it. I tried tightening the knobs this morning, but they already were. I think i'll just have to take the top and pads off.

I wonder if the sound bar is not bolted down? there are supose to be 2 torx head bolts on each side of the sound bar, i think you will have to have top down to check it, or you could just try to push on it and see if it moves..

You know, if I had to take a wild guess I think this might be it. I was wondering if they were any bolts (movable parts) associated with the roll bar. I thought that it was all one piece, but if it is piecable I would be willing to be that is what's loose.

roll bar is what keeps you safe the sound bar is the bar above your head that has the speakers in it.

The bars that connect your rollbar to the windshield are bolted. If they are loose, they will rattle. When the noise happens, grab that bar just above your left ear and see if it deadens the noise.

I took mine off so that I could remove the padding without cutting it and didn't bolt it back tight enough. It's a theft proof bolt (torx with a center nub in the middle) so it was a PITA to remove and put back on. I replaced the bolts with metric grade 8 equivalent hex bolts and tightened them up enough to stop my rattling. At one time I even had 3 or 4 zipties jammed in the crack trying to get rid of the rattle.

Wow, great advice, thank you. I'm going to record the sound and post it then. I'm nervous about tearing the top off this weekend in 35 degree Pennsylvania weather, but I may have to do it.

You can see the bolt I'm talking about with the top on. There are two torx bolts holding the bar to the windshield and on big one holding the bar to the B pillar. It'll on the top a little to the inside. It's the big one that's most likely loose. The bolt won't feel loose but if you use some muscles to try to move the bar it should not move at all in any direction. If it clicks, the bolt isn't tight. You can try a nice set of vise-grips or buy the security socket for about $25. I tried drilling the nub off but that didn't work at all.

Best thing i can compare my sound to is a loud ping, like if a hammer hit metal pipe.

Ping sound to me would have to be hardware from the bars that go from windshield to rollbar being loose. I had sound pods on mine so can't tell mounting for the sound bar---my after market sound bar used sheet metal screws for mounting.

I'm assuming the connection you're talking about would be behind my head near the sound bar intersection? I should be able to get into there without taking the top off right? I messed around with it for a few minutes last night and couldn't seem to get a feel for or get my eyes on any hardware. And you guys are saying there's a special tool for it once I do find it?

You may have to slide your padding forward a few inches to reveal the bolt. You can get a tool for it but I just used vise-grips on mine and took the bolt into Lowes to match it to a hex bolt (Metric grade 8 equivelent).

Well, I got to the hex bolts on the sides this past weekend and they were both as tight as can be. With the padding off I was able to more easily identify where the sound was coming from. It looks like the bar meets in the middle and one side slips into the other side. It sounds like the cracking noise is coming from where they meet in the middle.

I'm kind of at a loss now because everything that should be tight appears to be.

Smile Bolt size

Hi Gents,
I have been fixing my. 92 Jeep
This forum has been great!
My first post,

I'm also having this issue with the roll bar noise.
I checked tonight and the bolt is Mia

I know some said metric grade 8

Do we know what size it is?

Also was a washer needed?

Thanks
