Yeah, the Arnott AS-3381 product page even says that it features "Multi-ply Continental ContiTech air sleeve". I figure my car must have a single-ply Firestone no-tech air sleeve.

I have heard one Tesla S owner complain about this for several years. Only to find out it was a simple fix with front disc brake pads clunking.

Alright, Iām jumping in hoping yāallās Insights will be helpful for me as well.
My 2016.5 P90D has a bad clunk/rattle from the front left, and Iāve replaced or examined everything except the struts.
I had my original front struts replaced with the 77-Cās back in 2019 because of noise at low speed. As with everyone else, that noise came back after a few months, but it was minor so I just dealt with it.
Now, I have a very loud clunk/rattleā¦but strangely, I can only hear it with the windows down. I still think itās the struts, because it lines up perfectly with impact of bumps and Iāve inspected or replaced every other component.
Here is my thread on my sound, with a video sample:
teslamotorsclub.com
So, at this point I think Iām going to replace the factory air strut with the aftermarket Arnotts and see if that fixes things.
I was also considering the Unplugged Performance struts, but it looks like they actually still use the part of the factory strut that rattles, so I think thatās out.
Arnott might be the only permanent fix. Iām going to go ahead and do front and back because my backs feel soft - Hoping this does a lot for the car!

Clunk from the Front...NOT the usual suspects
Hi folks, I have a clunking noise coming from my front driver side when going over rough roads (not 'smooth changes' like speed bumps). I have checked the usual suspects: Sway Bar end Links - replaced with new Fore Arms - checked bolts, checked bushings with crow bar Aft Arms - checked...

I would recommend asking Tesla to investigate the source, they have great guys who have the ears for that
Here in Canada, the price is around 90$.A lot of parts around the suspension could cause this noise. I listened to your video but never heard this kind of noise. In my case, it was more like a "ping pong" noise, like the coil spring is hitting the aluminium casing of the struts. Yours sounds like something loose and clunking against metal. Maybe a rock in the brake disk or a loose brake pad?
On my tesla Model S, Tesla changed:
FR UPR CTRL ARM, RH, DUAL MOTOR(1043966-00-B) (Creaking noise over bumps)
FR SUSP AFT LINK ASSY(1027351-00-C) (Rubber was worn out)
FRONT STABAR LINK - DUAL MOTOR(1030603- 00-B) (ref:
The stabilizer bar (can't find the part number yet. Rubber was worn out and starting to get loose.)
Shock Tower Braces: RH - LHD - SVC NVH(1064611-S0-B) and LH - LHD - SVC NVH(1064610-S0-E) (reduce the problem of the 77-C struts or even resolve it? ref: Rattle noise coming from front Air Suspension (2017-18))
Tesla realign one of the brake dust which was making a vibration noise when hitting the tire.
Everything helps a lot but the ping-pong sound at low speed was not removed until we changed the struts. Because the struts 77-C don't seem to resolve the ping pong noise at low speed, I decided to try the Arnott. Up to now, very happy with the better ride quality with hope they will last better than the OEM...

Thanks for the insights - yes, my noise does sound like something loose and clunking. I have mobile service coming by on the 11th for something else, so I'll see if they have any thoughts.

Just a general Arnott note from skimming their website:
Interestingly, their offering for AWD vehicles is made from Continental components, and the offering for RWD is made from Firestone components.
Since they mention it's OE, I am curious if that's the same Firestone components that cause issues in the stock struts, just white-labeled for Arnott.
Definitely make sure you get the Continental ones (the part numbers that jcpetit mentioned)

Well, my sound ended up coming from the inner bolt on my aft arm being loose, and not the strut:
So, my struts do work as they should. But with that said, I already have Arnott's in my garage....are they significant enough of an improvement over factory that I should still replace my factory struts with them? My car has 41k miles.

Do you have the 77-C struts ? If you do, they should be good up to at least 100K.
I had the older ones and my car was around 140K km when I changed them for the Arnott. Also, I'm in Montreal, Canada where roads are very bad and winters very harsh...
But my EV garage and I agreed that the ride is better with the Arnott (Not scientifically tested). We just don't know how they will behave in the long run.

I have the 77-Cās up front, theyāre 2 years old. I have factory struts in the back, theyāre 6 years old.
They perform okay, but are a little āsoftā for my liking, and they kinda wheeze over speed bumps sometimesā¦they just feel low quality IMO. I hear that the Arnotts feel firmer and more planted, but thatās from a very limited number of reviews available.
hello
I also have noise from the air suspension Model S refreshed from 2017, I would like to buy the suspension from Arnot, can anyone tell me if the height calibration needs to be done at a Tesla dealer after suspension is changed. I would like to change it at a local service because the nearest Tesla service is over 600 km away and they dont have diagnostic tools for Tesla cars.
Thanks

Hello.
Are you sure the noise is coming from the suspensions? I would make a diagnostic first, the noise can come from a lot of sources.
Usually, the first cause seems to be the sway bars. then the control arms, the bushings of any parts and finally the suspensions.
The sway bars are new...only at low speed under 25 km/h the noise can be heard and is very annoying...if I drive on the same bumpy road with 50 km/h ore more,I can not heard nothing.
I had that noise issue and this is the post that applied to me. They ordered new parts but the same version 1 and the same issue occurred. So they are now ordering version 2. (Why they didnāt order version 2 the first time is beyond me.) In the meantime they put in some foam to help with the noise and it did make a big difference.
Rattle noise coming from front Air Suspension (2017-18)
Thanks @dougpy - I'll have to check the part number on my air struts next time I get a chance to see if it's different... BTW, noise still gone? @tkizzy the noise you described sounds very different, both in character and situation. The air suspension issue we've been discussing sounds almost...
teslamotorsclub.com
This is from my invoice. And I did have them order version 2.
āConcern: Rattle or squeak - customer states: Unfortunately the upper control arm replacement that I had done yesterday did not resolve the rattle/clunking issue coming from the front of the vehicle. Noticeable when going under 20 down bumpy roads.
Verified concern with customer, removed and replaced both shock tower braces. Noise is still present, however upon Installing foam in-between strut tower and brace isolates noise. Found that part that was replaced was a direct replacement and not the revision with rubber isolator, If noise persists, braces with isolators will need to be ordered and installed at new appointment.

It looks like we have now shock tower braces with rubber isolator to mitigate front noises Could you tell us if they are the parts RH - LHD - SVC NVH(1064611-S0-B) and LH - LHD - SVC NVH(1064610-S0-E) ?
Also, do you already have the 1067361-77-C front air struts?
I have now the Arnott air struts in the rear and front. Everything was much better for a few months. But now for a few days, I started to hear weird noises, this time at the rear (both sides), mainly at low speed on rough roads. I have an appointment in 2 weeks to check it out. I hope it isn't the Arnott rear struts... I sure let you know when we find out.

Height calibration is not necessary after changing air struts.
I hope not.....because they'll damn sure blame it on any aftermarket part that's in there! Tesla won't even diagnose my rear suspension because I have aftermarket adjustable control arms.
I would describe the noise as significantly reduced to the point where the noise is not noticeable unless I listen for it. So for me, it is virtually silent. And yes, the upgraded shock tower braces are still working, and I've not noticed any return of the noises.Hello Transporter73,
are your struts still silent after a few months?
Thanks
Hello. Just wondering if anything was discovered about the noise.This is interesting

I have a 2017 S75D, with the clunking noise at the front, and I'm considering the Arnotts.
