The strut I used in this video as replacement is aftermarket and made by a company called Arnot.
Thank you for going through this nice and slow and really getting the camera in there so we can see wtf is being discussed. I still don't know how I'm gonna get my big fat arm up in there to that plug but at least I know how to direct a skinny helper now... hahaha
Thanks for explaining this project in detail as you actually performed the removal & replacement. You did a very good job. 👍 Great video!
Your very welcome! Glad to hear it. Thanks for the kind feedback ✌️
@@MercedesTech Does the same procedure apply for the driver side rear installation? Also, can you purchase just the hardware that's suppose to come with the strut? i
@@TheRutt1962 exact same for other side, just a mirror of it.
@@TheRutt1962 not sure about the hardware, usually have to reuse bolts. But I believe you can get some hardware from a dealer or a third part website like autohausaz.com
This video is great I don’t even have any issues with my air suspension but now if I do encounter it I’m not going to worry so much , someone told me it’s £1000’s to repair but I can do this with some time and patience. Thank you man, btw your calm explanation is amazing
I was very impressed in what Detail You show the entire Procedure ,nothing was left out !
wow, that was a lot more simple than I thought. I took my car to a shop to get fixed with this same problem, turns out I could have done it myself if I had not been spooked to think it was super complex :D oh well, next time I will give it a try
Excellent camera work, lighting, positioning yourself out of the way so we can see your hands work and not the back of your head😉. Always amazes me how you expert mechanics can almost literally do the job “with one hand tied behind your back” bec that hand is sometimes holding the camera. Also, knowing that you worked at the dealership tells me that you you performed this maneuver in the best possible way. Kudos to you Sir and thank you for giving confidence to this “shade tree mechanic”.
Thank you so much! I appreciate you noticing the work that went into the video 🙏
thanks for this video. Today I have been replacing rear strout in my S500, and in one moment needed help or advice, your video did it :) In my case the brake calipers stayed in place, and also I did not unscrew bottom arm. To remove strout I have used a strong steel bar lever and soft protection foams to push down whole wheel system and it worked like a charm. Also pressure pipe I have installed different way, and screw in place.. Anyway repair were succesful, took me almost 2 hours to complete and tomorrow I', going to replace other side, probably in half of that time.. It is not that hard as front strouts.
Good video I like that you take your time and give the precautions and limitations associated with the job also the nut and bolt sizes. On another note I use the rubber mallet also saves your elbows in your wrists and also it’s a hell of a lot easier. Good job
Thank you! I appreciate the feedback! 🙏
Hot dang, that little trim piece to get to rear struts is pretty rare in a sedan. Usually have to pull the whole shelf. Nice
Exactly! Watched my coworker do the rear struts of his bimmer wagon and he had to gut the rear of the interior to just see the bolts! One of the many reasons I love MBs
The lighting Is perfect I’m going to do this job myself and this video is going to help me out thanks bro 🤟🏾
Having reviewed the video from Bilstein (air strut manufacturer), and found that the rear suspension could be replaced without removing the brake caliper, simply squeeze the strut carefully through the tight sapce.
The brake line is my biggest concern when doing this repair. I try to avoid getting even close to stretching it. If your try to do a flat rate job, go ahead. But I wasn’t and usually aren’t in a hurry in my repairs. The lower suspension has to bend down quite a bit to get it out. If you compress the old strut (if you can) cool, but it’s not recommended to compress a new strut and I don’t think possible as they are very stiff.
I was gonna say WTF is the point of that lmao
My 2005 s500 airmatic is just leaning on the passenger rear. It is worst in the morning but will air up once i start the car. I have no warning lights at all. the other sides are sitting fine. Do you think this is a strut issue? or could be it be a sensor or valve block etc?
also how many hours of labor is this usually at an independent shop to do one strut? thanks for posting this informative video
It’s definitely the strut. Mine did the same thing till it stopped airing up. It’s very easy just get your hand dirty and watch these videos.
Best video for shock replacement
Hi, thank you for the video, i must remplace one of my strut and i'm asking the air pressure in the airmatic system doesn't make problems in the remplacement ? When you dismount the pressure pipe?
Dude my respect's to you thank you for showing me how to do this :) w220 all the way :)!
Your welcome! Glad it helps. 👍
Hardest part was definitely putting the strut back in the right spot i recommend taking off the back of the control arm to get the new strut on using a t55 torque bit and a size 18 socket
I appreciate your comment , I was struggling
Is it really necessary to remove the brake calipers and things?
It makes it easier to push the lower control arm down which also avoids stretching or breaking the brake hose
Awesome video - very helpful to know what is involved. I am currently in the middle of this project and it was quite tough to take out the rear strut. I had to loosen the 18mm bolt few turns where the spring arm connected to the frame. in terms of re torquing (the last bolt to torq) that bolt, does it need to be done when the car is on the correct level on the ground or can it be re tighten with the jacked position?
It is always tightened while the wheel is off and vehicle is still lifted
@@MercedesTech Thank you
Any suggestion if you break that gapped disposable piece you squeezed and don't have a replacement? The clamp for the tube that goes on top of the strut. 😢
You should be able to use the old one, especially if it’s still on the line. There’s a small risk of it leaking but I’ve never seen it personally. You don’t really want to spread it apart as they do crack in half very easily. Otherwise you may be able to get a replacement at the dealer separately or online
Very well explained repair, thank you
You’re very welcome!
Big shout out to you for making this video 👍🏼
Could you please tell us all the torque specs when you put them all back. Thank you for the vid
@Mercedes Tech, I have the exact MB model 2000 S430 that you worked on, I replaced the rear right struts and followed the exact steps, here is what happened: my compressor didn't turn on, the left rear and front struts stuck on the highest level, Pressing the raise button didn't take any action. I didn't see you disconnecting the battery. Any ideas?
I would probably disconnect the battery and let it sit for a bit. Did you ever get it back up?
@@MercedesTech Thanks a lot for your quick response; much appreciated. I did disconnect the battery, and now when Pressing the raise button, it says it's raising, but the compressor did not run, it sounds like it is trying to level, but the compressor is not kicking in.
Be sure to check the big orange 40 amp fuse and relay for the compressor
Hi, I replaced the relay. The fuse is good. The compressor starts and the car raising sign-indicator turned on, but it didn't do it, still high on the driver side and low on the passenger side (no change); after multiple tries, I turned the car off for a while and turned on, the compressor didn't run, seems the relay may be burnt?? Not sure what is going on :(
Seam more likely that your valve block is hanging up. Not sure why only one side of the car would not raise. Do you mean only the right rear corner isn’t raising? I’d that’s the case, I’d check to be sure your ride height sensor for the low corner is plugged in and not damaged.
thanks for the detailed instructions
how is the ride with the arnott compared to the original strut? just as smooth?
Yea, pretty much the same. If your real picky you might notice decrease I. Ride quality but it was fine for me
Great job man !.
That was a great instructional video, thank you. I do have a question, I read somewhere that when using an aftermarket air suspension replacement part, it is recommended to replace both sides? Would you give your professional opinion regarding this? My rear driver's side leaked and I am deliberating if I should buy one or a pair. Thank you again for your instructional video and your time.
Thank you! You can replace only one side if it’s just the one causing issues. I would try that first to see how you like the ride. If it feels off or inconsistent to you, do the other side as well.
@@MercedesTech Thank you for your response. And I'd like to add that your calm demeanor while doing difficult mechanical work is very impressive.
Do you have to disconnect the batterie when removing air suspension?
You should always disconnect the battery
I have the same right rear that went down yesterday,if I use the lift button it comes up,but it drops,all the others are correct height,I would suspect shock?
Please, I need your help! tonight where I parked the car behind the car there was a non-metal obstacle I climbed over going backwards then when I got off it was a little high I suddenly went down and my suspension on the back now gives way and appears on my dashboard stop car to low can it be a hose or both cushions? please give me some advice
You will want to get the underside inspected to see if a ride height sensor or hose/ wiring was damaged
Very very very very great video
How did you get all the bolts off almost all of them are torcwued on I can’t get them with my wrench I don’t have any high torqued t tools
Put a wrench or socket/ ratchet on it and hit it with a rubber mallet until it breaks loose.
Great video guy. Thanks.
Why does the caliper need to come off when removing the strut? I’m asking because I’m removing one from the salvage yard and don’t feel like taking off the caliper is necessary.
Just to eliminate stress on the brake line when you are passing down on the wheel carrier
Is all years done the same
Where do i buy these parts 😢
It's excellent, but I deed the same job on my 2005 Mercedes SS 500 my right rear side is almost one-inch lover ??? Why I don't know??? Maybe somewhere have so a small leak that can be not found , because I driving that car and when I stop after 10--20 miles looks the same thing. S probably is not leaked but still is right side not in level. Any idea guys??
That's normal
شكرا sehr gut gemacht
Great video
Thanks great work
Nice video! subscribed.
Are you local too the Bay Area? If soo do you offer automotive repair services? I sometimes do work on my own but sometimes get lazy or don’t have the time lol.
I’m not in the Bay Area. I’m hours south of there and moving out of state soon. Sorry, just too busy in general to even work on my own cars most the time.
I wished you live near me my 2011 Jaguar same problem and suspension compressor died as well...lol
I gotta raise the BS flag on your demo. Having just doing this job tonight, there was no way in hell my lower arm was going to budge with the sway bar link installed. Even then, I had to loosen the inboard bolt on the lower arm. Note to anyone else doing this, tighten that inboard bolt with the car back on the ground. I went with the cheapest chinese air struts I could find. If it lasts 2 years, that's long enough to send this miserable joke of a mercedes FAR OUTTA MY LIFE! And mine only has 40k miles, looks like a time machine it's so clean. Hope someone else loves it enough to put up with its horrible build quality and quirky electronics. No thanks! F these cars.
Thanks for that much appreciated
My I get a link for the suspension part
I used RockAuto.com and no I’m not sponsored or affiliated in any way.
@@MercedesTech thank you
rear shock air pipe going
Funny how you left detaching the electrical connector off camera when it’s the most difficult part if you are not familiar with those fucking connectors.
18! I have a 911
