I've heard about the Hemi tick but mine went away within 30 seconds after starting the Jeep. Yesterday I started up my Jeep and immediately noticed that the tick was WAY louder than usual. The noise continued (more so at low RPMs) the entire time I was driving around town, which has never happened before. Even weirder, suddenly road noise became much louder. A car in front of me went through a puddle and I could hear the splash and also what sounded like slight wind noise coming from the driver and passenger feet area. I was completely confused as both of these things happened out of nowhere. I have no idea what this could be, as illogical as it sounds I thought maybe a sound deadening panel had somehow come off? I'm calling my dealer but just wondering if anyone has a guess it this was completely bizarre.
 
Do you park your 392 outdoors? I’ve noticed a change in sound due to the colder temps recently. I am also very OCD about things so once you hear a sound it’s almost impossible to not hear it.

No it's in a garage. I was warmer here yesterday than a few days ago. It got down to 24 and I didn't notice the tick or the noise. Upon closer inspection, the noise sounds like my climate control fan is set on low but it's turned off and no air is coming from the vents.. The noise is only while the Jeep is moving....so weird.

My 13 YO son, who is an auto detailer found the rubber plug for the drivers side rubber floor mat on the floor of the garage. Without that, you have a direct hole where you can see (and hear) the road below. I had no idea that my Jeep had nothing between the driver and the street but a 2 inch piece of rubber in that particular spot but now I know. Is there anyone who sells a sound deadening floor liner for the 392? Thanks!
 
Since you noticed a difference once the plug was removed it sounds to me it does a pretty good job of sealing things up.

Yes I'm just picturing how much quieter it would be with sound deadening on the floor.

Nice find sir. Thanks for sharing the info.

I put this product in my 2006 Wrangler. It from Amazon, Noico. Very happy with it.

I'm getting a strange ticking sound when I get above 70 MPH, which makes me think it’s wind related. I know it’s not the “Hemi tick”; I had that on my Ram 1500. The Hemi tick is rhythmic; this noise is random. Anybody else experiencing this?
 
That's interesting. You would think wind noise at that speed would make any engine related sounds less noticeable, not more. Your first guess is probably accurate.

I don’t think its engine noise. I think something else, something that lays dormant until 70+ MPH air hits it. I will investigate and report back if I figure it out.
 
CBH, I seen somewhere on the one of the Forum's, where someone was missing one of the floor plugs and could hear and was getting weird road noise's.

Could it be the inner fender liners? There are reports of those coming off around 80 mph.

Could be they are flexing or vibrating? I will take look at them. Thanks!

If I remember correctly, there have been cases when they have come lose at, or above 80 mph, and there might be some kind of real on them where the dealer is ether replacing them with an upgraded design, or better tabs, I do not remember. But I think that could be your issue, if Jeep ever decides to send me my 392XR I will let you know if I have that problem when doing 80+ mph... LOL.
 
Im having the same issue with my 392. I noticed anything over 70mph I start to hear a random clicking noise. is it the fender well or is something else vibrating?
 
The driver side inner fender blew out the day after I took delivery of mine, it rubbed against the front tire and made quite the racket. I was driving over 80, in a headwind when it happened. I have a set of AAL inner fenders that I'll be installing soon.

Do you believe that was heat related? Others have suspected that.

Yes, I believe It was a combination of a bad design, along with driving over 80 miles an hour in the heat, with a headwind that was at least 20 miles an hour.

Here’s a picture of it after it happened.

I too have had a similar issue, I’m suspecting it is the flaps on the cold air intake located in the hood
