Really not sure when this started happening, but I now hear it more and more. Very possible I am just hearing it more as I am trying to listen now.

Nearly every time I put the Jeep into gear (auto) I hear a "snap" type of sound. When I drive slowly and hit the gas normal and then off the gas I hear a "click" sounds. I am guessing it happens at any speeds, but the faster I go the more wind I hear so can't hear as much. Its not super loud as you really need to be listening to hear it.

I have tube doors so I am able to really lean over and listen and sounds like its coming from right below me.

I am going to look at the Trans fluid this evening, but what else should I look for?

The diffs are both full, and oil level is fine. Checked those this weekend, as I honestly thought it was the rear diff since I had the gears upgraded a few months back. All fluid levels were fine :)

Jeep is a 16 JKU Rubi with 44k on it. Thinking I might have to bring it into the dealership, but afraid of what the bill is going to be :(

Anyone have any ideas what to look for?

Take your time with this one

There's a ton of possibilities. Could be a trans issue, or could just be linkages that were in a bind when the vehicle was parked. My 07 JKU clicks and clacks all the time and i've taken it to various mechanics and dealerships and they have reported all is good to go. It really depends on a lot of different mechanical factors that can influence the way that the vehicle responds to tension & stress.

if you changed gears that is the first place I would look. your tranny will still has warranty as 16's have 5/60,000 drivetrain warranty. it is possible gears or spider gears are the issue tho and being gears were changed nix the warranty there. just because the diff oil level is fine does not mean that is not the problem. too much back lash, broken spider gears etc. pull the drain plug and look for metal.

The diff fluids were changed at 500 miles, and at 5k miles, and both times everything was clean. At the 500 mile mark the covers were pulled off to inspect things at the shop that did the work. Everything has been clean thus far. I have about 7.5K miles since the new gears went in.

I will be checking the trans fluid this evening as I wanted the Jeep to sit over night and cool off before checking. I kinda hope its just low and easy fix.

Since I started rolling around with tube doors I hear a lot more things now, which can be good or bad I guess.

I will try to have the better half start the Jeep while I slide under and listen. The Jeep is tall enough to not run me over :) If I hear the noise around the trans then will bring it in for them to look at. Forgot I still have a warranty on power train. If its more towards the diffs then I will pull the covers off and inspect them.

I'm getting the same kind of noises from mine which is all stock. Off and on I get it when shift into reverse out of the garage, but I tend to hear it more so when I accelerate from a stop, and as I let out of the throttle it does an upshift at the same time and makes the snapping sound.

At some point I'm going to slide under it and check looseness in the driveshafts. If nothing seems obvious I'm going to pull front driveshaft and check to see if sounds go away. It's been making noise for as long as I can remember so I'm not in a huge rush, though I'm at 57,000 miles so maybe I should look sooner rather than later if it is drivetrain related.

I was able to check the fluid when hot and cold and its in the normal range and looks fine.

The sound also happens if the Jeep is warm or cold. It doesn't happen every time I shift from P --> D or --> R but it will make the noise when going slow and hitting the gas off and on.

I will still try to get underneath and look hopefully this weekend. I may also just for peace of mind drain the rear diff, and possibly open it up to look inside. Will depend on if I see any metal pieces while draining.

I am leaning more towards a linkage type issue, which it is what it is unless its something simple to adjust. I just hear it more since I have tube doors on, so who knows how long its really been going on.

My 2017 JKUR does this. When going park to drive there is a clank, sometimes loud. (stock btw). The click when hitting the gas is also present. Louder in 4lo. Take a video if you're concerned and I'll take a listen. I've heard exactly when you're describing though on multiple Jeeps.

I listened under the Jeep while the better half moved it from P --> D or P --> R and was able to see the shifter linkage attached to the side of the trans make the "snap" sound. I spayed it down with some teflon greese, but still makes the noise. Nothing major since I can see where its at now. Its moved perfectly fine, just once in a while makes the noise.

As for why it makes the noise when I tap the gas pedal I am not sure, but its the same sounding noise.

This point I am happy its not the rear diff, and can live with the noise. The doors will be going back on in a few months anyways, so to me the noise will disappear.

Thanks everyone.

fyi
our 2015 JKUr has been doing that reverse snap since I bought it. Closing in on 56K mile. Does it early in morning out of the garage then quiet rest of the day.



No other noise from the tranny. Also remember hearing that from our friends Dodge Minivan back in the 90's. Not sure if that helps but just another data point.

Doubtful if this applies here, but my brother had a similar sounding snapping noise on his automatic Escape a while ago. Took me a while, but I figured out it was a loose axle nut on the front driveshaft.
