Mercedes Driveshaft Flex Disc Replacement | No more clunky shifts!

Hear a loud CLUNK every time you shift your beloved Mercedes into reverse or drive? Your Driveshaft Flex Disc could be going bad and needs to be replaced! Very common issue on ALL Mercedes models. What happens is the rubber begins to dry out and crack causing all kinds of vibration like you see in the beginning of the video. This part is made to reduce the vibration between the driveshaft and the transmission.
In today's video I'll show you how to replace the flex disc quick and effectively. The car used in the video is a 2000 Mercedes C230 Kompressor, but this is same procedure for any Mercedes model with this part. (C / E / S-Class CLK SLK W210 & more)

how cool me Already Ia speak what these tool your Are much good principally at Screwdriver gives Milwaukee.

[@aironmendes5973]

Here in Brazil no sells gives Milwaukee sells others brands as The American Dewalt have an drilling machine The drums her much good also but ever quiz an Milwaukee who You know one day I buy an of that Thanks fur link in purchase. 😉🤝👍

[@chadg6874]

I was looking for a video like this a couple months before you made it! All the other ones show the part and talk about it but dont actually show you how to do it. Lofe saver!

[@Mechani_Cole]

Glad it was helpful🤙🏼

[@Bethkimphotos]

thank you for this very clear and bright to the point

[@aironmendes5973]

Another outstanding video! 🎉

[@sonidoritmoyclase]

Really good video thanks gonna try and do that soon

[@angturil]

don't forget to mark the drive shaft before completely unscrewing and removing the discs, it is balanced and you don't want to lose that!

[@user-iw6dr9rb3b]

You have to mark bolts or position

[@AlexanderRau]

well made brother, thanks for sharing!!

[@Mechani_Cole]

Thanks for watching and commenting 🫡

[@malcolmmcfarlandsr.3591]

Great video thanks!

[@Mechani_Cole]

Thanks for the comment🤙🏼

[@bigfather1279]

nice video clear and well filmed also . did u remplace the other flector on the back?

[@Mechani_Cole]

Thank you, and no I didn't. The one in the back didn't have any cracks and looked really good still

[@agushendro4743]

Very useful video. Btw newbie question, did you put the car shift in P or N when doing this? Try to find info in google so far no luck.

[@Mechani_Cole]

Good question! Neutral is what I did. After the car was in the air and secure of course.

[@justice4romania96]

Hey! Why was traces of oil on the trim over the flex disc? I have the same problem, yet the seal is dry. Thank you!

[@Mechani_Cole]

Good question. Maybe Grease was used during install from factory and spins out? Not sure, didn't seem like an issue on mine

[@tonymyersnz]

Awesome video, thanks! Would this issue also cause a small/barely noticeable vibration? Mines definitely cracked and needs replacing

[@Mechani_Cole]

Thank you and yes! I'd suggest doing transmission mount as well since it has to be removed

[@tonymyersnz]

@@Mechani_Colethanks for the reply, do you happen to have a part number for that? Much appreciated.

[@tonymyersnz]

And on another note, I am sourcing this part atm, I believe it is 0004110200, would this be okay for a w219 CLS350 2006? Again, thank you!

[@Mechani_Cole]

@tonymyersnz both should be listed in the description

[@tonymyersnz]

@@Mechani_Cole apologies, I am wanting to confirm if this will fit a w219/cls350 as I could not see it listed under the description/ebay listing

[@kendalgee5808]

I would go with OEM only. I had a nightmare of a time using aftermarket febi bilsteen front sway bar busings. They squeeked like crazy. When I went back to new OEM bushings = back to normal. Cheap out on the part, you will pay later when you have to do it 2x with an OEM part.

[@Mechani_Cole]

I disagree. I've been using this Febi replacement for about a year with now issues.

[@kendalgee5808]

Febi Bilsteen replacement what? Flex disc or sway bar bushings?@@Mechani_Cole

[@Mechani_Cole]

This video is about the flex disc. That's what Im referring to. I don't have a video on the Sway bar bushings

[@kendalgee5808]

Good to hear the Febi Flex discs work well. From my experience the Febi sway bar bushings squeek really bad even when u grease them. @@Mechani_Cole

[@Mechani_Cole]

@kendalgee5808 good to know as well🤙🏼

[@ahd5764]

Can you help me with a question? I have a cls w218 and at high speed if I take my foot of the accelerator quickly, it gives a kick, sometimes stronger, sometimes less strong. It seems to be heard from behind, and I think it is from the cardan, driveshaft flex disc, or something. What do you think?( the gearbox shifts very well, but i think I need to change the gearbox oil. In that condition, that could be a factor?)

[@Mechani_Cole]

I would change the gearbox oil first. I'd also replace the trans mount if I was you and see if there is a big difference

[@ahd5764]

Thank you!

[@DrOdTtg]

I have a ml350 05 and when I put it in P and D n R I hear a clunk and when I drive I hear it in the shifts too I think it’s the support bearing could it be this ?

[@Mechani_Cole]

You can usually visually inspect these and see the wear and tear. Lift it up, put it in neutral and grab the drive shaft. Turn it back and forth and see where the movement or clunking is coming from

[@talklacey664]

Is there a front and back side to the flex disc or does it not matter which way it goes ?

[@Mechani_Cole]

People have been saying there is a front and back, but both sides looked exactly the same to me

[@Sanneti2012]

Besides the clunking, is it possible that this bad flex joints cause intermittent vibrations thru the whole body?

[@Mechani_Cole]

Yes, but repalce the trans mount at the same time. Will make a huge difference

[@Sanneti2012]

@@Mechani_Cole i did replaced the mount already (ML350 ‘13 4matic) I noticed some change but there’s still some vibration. It barely has 100k miles. Thanks

[@Mechani_Cole]

@Sanneti2012 have you replaced the engine mounts? That should make a huge difference. The disc doesn't need to be replaced unless you see it's cracked or worn

[@Sanneti2012]

@@Mechani_Cole I haven’t but I noticed the engine being very stable, no jerking when accelerating. I guess I can try.

[@MN_ALGORITHMS]

Do you need to replace the driveshaft end bushing too?

[@Mechani_Cole]

If yours is cracked and worn yes

[@MN_ALGORITHMS]

@@Mechani_Cole thank you!!!

[@mienqchau]

I assume all wheels has to be off the ground?

[@Mechani_Cole]

It's easier that way. Can maybe do it with just the rear lifted. But I'd recommend all 4 corners

[@mienqchau]

@@Mechani_Cole good looks my guy! just have to ask!

[@bahissafg]

Watching this I don't even have a bicycle 🚲 🪖

[@Mechani_Cole]

It's never to early to learn🫡

[@bahissafg]

@@Mechani_Cole thanks I agree we appreciate your work you earned a sub and like I learned already alot. 🙏

[@aprilfisher2928]

Can the drive shaft be crack also

[@Mechani_Cole]

Possible I guess. But very unlikely

[@aprilfisher2928]

Wow this guy said my crack a little

[@aprilfisher2928]

Wish you can fix mines 😊

[@Mechani_Cole]

It can happen. I'm located in Vegas if you're anywhere close

[@aprilfisher2928]

3000 miles away

[@boninotate1305]

You forgot to mark the drive shaft

[@Mechani_Cole]

For what exactly?

[@angturil]

@@Mechani_Cole it is balanced. If you don't put it back in place the exact way it was screwed originally you will lose that balance. You MUST mark it at any cost or your brand new discs will wear out much faster than before, not mentioning the vibrations that it will cause. Mercedes WIS document AR41.10-P-0050-03SX. This is Mandatory on such operation

[@Mechani_Cole]

Thanks for sharing! So far so good about 6k miles later, will update here if I have any issues

[@luisenriquechavezdiaz3071]

Bro just ordered the part from Amazon and it didn't fit xddd

[@Mechani_Cole]

Did you replace the mount as well? Could asap be the rear one

[@luisenriquechavezdiaz3071]

@@Mechani_Cole i Will order from FCP euro the one on the description didn't fit my Mercedes w202 2000 c230 Kompressor since is a different part number, and yep I will order a new mount for the transmission

[@joshuaculley9695]

I only hear the clunking when I turn and am accelerating. It feels like the moon is messed up like twisting a chicken bone kinda crunch. Is that the flex disk or the universal joint?

[@Mechani_Cole]

Hard to say for sure without a visual inspection. Could be either, or bad tie rods/control arms if it sounds like it's coming from a wheel

[@joshuaculley9695]

It’s not coming from the suspension. The sound is coming from the center console part down from the hear shift knob where the tray is. I’ve got a 74 450SL Mercedes. I guess a better explanation would be when the car is accelerating when I’m turning and I can hear it and feel it as if the u oversaw joint was twisting as if you were twisting a chicken wing apart in a circular motion so when I let off the pedal the grinding crunching clunking noise stops and I slow down some to not engage it too much and damage it further whatever it is. I believe it’s the driveshaft just below that part. Wish I could post pictures. Also. Not sure why I was saying when I typed moon..

[@Mechani_Cole]

@joshuaculley9695 I see, that's a way older model for sure. I think you got it pretty close. I would assume drive shaft, or carrier bearing
