Heavy front rattle - video included

Hey gang,

Let me preface this by saying I did a fair amount to scouring the forum and checking a number of things before I posted this. So hopefully I have not missed something. I just had my ball joints done today, and that did not remedy the rattle, hence why I am on this mission!

OK so about a month ago I noticed a heavy rattle developing anytime I hit a manhole cover, or pothole....usually lasts a few seconds after, and sometimes affects the steering. I have checked the trackbar, swaybar links and nothing seems to be obviously loose when I put pressure on it, nor do any of the bolts appear to be loose. SO, I decided to throw the gopro under it pointed at the suspension while driving up and down my street, and put a post up to see if anyone sees anything obvious. I left the audio in thinking that might help illustrate the point....Note that some of that noise may be the stock plastic skidplate that is slightly loose.

If you have time take a look and let me know if this is anything obvious.

Also, happy to move the camera to another position if it would help to see it from another angle.

The video lives here:

Thanks!

Nice capture! Yeah, I got it as does another guy see here

2013 JK front rattle/clunk HELP!

so far haven't been able to isolate it yet as its so intermittent. For me its from the front driver side almost sounds like something in the engine bay when I do hear it. So far to date 1 year in almost no issues have surfaced even though it is still there.

Sounds like exhaust banging around to me. It has that hollow pipe sound rather then a loose solid steel part.

Hey I am that other guy! I did find my rattle it was driving me crazy. If you go under the jeep under the drivers side door. Look up and to your right. There is a heat shield that looks like really thick aluminum foil. It should be lined on the tub or flooring of the jeep. The only way the factory made this shield stay on is from integrated push tabs that go over the threaded side of a bolt. One of mine came loose and caused the shield to hang down and knock on the exhaust. I pushed the shield back on the bolt and threaded a nut on it to make sure it didn't happen again.

Thanks, that is good news! I missed your conclusion at the end of the old thread there. I'll have mine on the hoist soon for other work and will take a look. OP let us know if that solves your case too.

Thanks guys, All good info, I'll look into it. the one thing I will say, is that it "feels" heavy. Like I can feel it rattle in in the whole jeep when I hit some bumps. Its weird...just feels like something is deathly loose, but there is nothing out in the open.....gonna take a few more videos at different angles and repost

OP what part of Mass are you from? I am from Danvers, for some reason I think I have seen your jeep around. The leveling kit looks good I had one, but ended up returning for something a little bigger. If your clunk doesn't end up being the same as mine, I would go ahead and double check the sway bar end links since they were removed to install the leveling kit as well as the torque on your wheel spacers.

Fellow jeeper from Boston here... Can you feel the rattle directly onto the steering wheel and pedals?
I had quite a few clinks, clunk and rattles and every time i could feel them on the steering wheel.
X2 on sway bar links and re-torquing

Hey, I'm in the Worceser/Fitchburg area. So right before I had the ball joints done, I rotated the tires, and when I did that I checked the torque on the wheel spacers. pretty sure they were tight 80lbs all the way around.

When I gave it the once over the other night, I gave the swaybar a good tug and it seemed OK. I checked the quick discos, and nothing seemed out of the ordinary. Should I be looking for something more specific? Thanks again.

eldomi809, yup I can feel it in the wheel, have not noticed in the pedals, I will check today.

Honestly, when I had mine I swear I could feel it in the steering, but I think it might have just been me feeling the recoil of hitting a bump and associating the sound with that. As soon as that noise was gone my jeep all of a sudden seemed to drive a lot smoother over bumps. If you check my old post I also posted a video of the sound I heard inside of the car. I went over everything as well and then noticed that heat shield hanging down. The one thing that drives me away from it being anything major is that your jeep is a 2012 and fairly new. I am sure you have heard the whole intermediate shaft problem/fix/noise, but what I discovered Chrysler addressed this issue in the 2012-2013 Jeeps by installing a factory retainer. I literally thought my Jeep was falling apart the noise was so bad. It was also a lot easier to get at this heat shield when the vehicle was up on a lift.

Also any clinks/clunks while in park and abruptly moving the steering wheel between 10 and 2 o'clock. If so maybe have a buddy move the steering wheel while you physically check under. As well as rock the jeep side to side to see if this produces it? Are the shocks torqued and with good bushings? Sometimes if the bushing is worn it will look and feel tight but still make noise when driving

OK cool I'm going to look into all of the above. I've asked around with a few friends who I wheel with, and they also suggested the swaybar links too. Gonna reposition the go pro pointed at them this weekend and I'll post a new video of that. Thanks again guys! PS once I get this figured out, I want to get back out onto the trails, so if anyone is up for it in MA or surrounding areas, let me know.
