Thanks Tweak, will search him out

Does seem cars built prior to Aug 14 can have this issue and a TSB covers that. Sent to my dealer and waiting.

Other forums or Facebook, many have ordered them and many are giving good reports.

Resurrecting an old thread, but it's some relevant information.
I had recently changed out my strut mounts and installed Eibach Sportlines while I was at it, but was still experiencing a low-speed clunk from the driver's side. It turns out that my left control arm had a minuscule amount of play. So little play that it was difficult to feel and see when moving the wheel laterally with my hands. The culprit was a loosened front pivot bolt.

It's a bit of a pain to access this bolt as I had to remove the bumper cover and a portion of the sub frame (it's a bolt-in member; not sure what it's called) to gain access to the E18 external star bolt. The bolt wasn't terribly loose, but required tightening to 80 ft-lbs + 45°. I'm not a mechanic, but I assume the + 45° is to take into account that you cannot torque the bolt with the loaded weight of the vehicle on the suspension as the sub frame is not integral with the required portion removed.

Hello CNQCNTO. My daughter's Poppy also has a loud clunk and after reading the post I plan to perform the strut mount and jounce bumper operation. But what you posted is very interesting. Is the clunk gone?

 

[Silveray]

So I replaced both strut mounts and the clunk is still there. Looks like I need to dig in more into other bushing/arm etc. Also turning the steering wheel also causing some noise. Sway bar linkage looked ok, knuckles on them move smoothly and no slack.

Does the same issue with replacing the jounce bumper apply to the rear wheels? It's not clear to me, though it seems that most of this discussion has focussed on the front end. The clunking I'm experiencing seems to be from both front and back. How different is the setup in the rear?

 

[N.G]

I had the same "clunk" that is directly attributed to the cold weather. It was diagnosed by the suspension specialist at Downsview Chrysler today as having to do with the rubber front suspension bumpers or something like that (I forgot exactly what he called them) shrinking in the cold and failing to muffle the sharp bumps. The parts are supposed to be on back order so as soon as they get them in I'll let you know if it fixes the problem. He also assured me that the clunking wasn't an indicator of bad things to come from the suspension so I shouldn't worry while waiting for the parts.

Hi has your issue been resolved,
I have the same issue,
Did anyone pin pointed this issue?

I am a Fiat mechanic in Canada and have been pulling my hair out trying to find & fix this clunking noise. Most Fiats I drive have this noise but not everyone complains about it. I have noticed that when the vehicle is on the hoist, the upper strut-mount moves in the body-pocket. We have been replacing the upper strut mounts & modifing the upper strut plate to hold the mount tight in the body-pocket and this usually fixes the noise but some cars are still clunking. Was hoping someone on this site had more info. My shop-foreman said that a new style upper-mount is being made but I don't think this is the only problem. Someone said something about the steering-gear causing the clunking?? Any info on this noise would be appreciated

I had a suspension shop look evaluate the problem, and they reported back that the Steering Column Joint is causing a clunking noise. Not severe or dangerous at this point, but eventually should be replaced. So this affirms the info you have heard as well. Maybe it's not the only issue, but a contributing factor. The suspension on my car checks out as being fine.

Here is a quick video I recorded of the sound I am getting. It's when I hit a bump or pothole 1.5-2 inches or deeper at speeds above 15-20. The sound gets louder the deeper the pothole is and the faster I get (to a point).

Hi , hope all is well
Having the same sound issue coming from front driver side when going over potholes at a certain speed,
I see you have posted a link for a diagram but I unfortunately the link is not working.
that said has your car been fixed? Do you know what’s the issue?
My mechanic changed the shock then links but the enoying sound is still there... did anyone in this forum has the answer?

Hi any idea finally about that TUK NOISE ? It only happens on a certain speed going over Pot Holes ...
changed the shock , links... it’s still there ,. Very enoying !!!

Canadian 500 Turbo on a same boat.
Annoying clunking noise on certain speed like 20-50. When i lift up the car left shock looks loose at upper mount. I just got the upper mounts to get them replaced, but as i read i that might not solve the clunking noise over a potholes.

Also i hear a noise when turning the steering wheel on very slow speed, usually when i reverse out of my driveway.

@N.G Did you also replace the upper strut mounts alltogeather with the shocks? i just wanna save doing same job twice lol

As I mentioned above, I would check your steering column joint as a potential source of the noise.

I have a 2013 fiat and I've replaced the jounce bumpers and the top hardware assembly of the strut. Still cannot get rid of the clunking noise when hitting small uneven road surfaces. Could it be the axles sliding in and out of the transmission? Ball joints and tie rods are tight. No play there.

 

[JoeinCA]

Any one has an experience if i go and change the jounce bumpers with aftermerket like Sasch or KYB will solve the issue, or go with a pair from dealer.

Already got a top struts mounts but trying to figure it out that anoying sound over small potholes, still never replaced those.

i drive 2013 500T

Check your axles. My passenger side has a little movement and makes a clunking sound over small bumps or potholes. Grab your axle and see ig you can move it in and out to recreate the noise. Jounce bumpers are like bump stops. Unless your bottoming out your struts you wont get any noise from those

 

[midwayfiat1]

It's the jounce bumpers and or intermediate steering shaft.

 

[streetsurfer]

Front jounce bumpers CAN slide up and down on the shaft. The rears are fastened to the frame and do not have the strut or shock shaft inside it to force it loose. The surround the strut shaft on front, but only press into place at the top. New design contains larger inner nibs in the bore that press against the shaft. The top connection can still come loose on the uprated bumpers. This creates more of a plopping sound, sometimes two or more in very rapid succession as the bumper slides up and down the shaft in a impact/bump and makes the noise when it hits bottom and top of strut. At times it may re-insert itself at the top and hold for a time only to be knocked loose again later. Sounds more like a cork pop gun going off. Multiple hits... “ploppity-plop”.
