Hello everyone
please welcome and join me in Easy Steps today I'm going to share with you my
Mercedes GL550 model I got a problem, my back air suspension has gone bad
This is how the suspension looking in the front, if you see a lot of
gapping and if we look at on the rear and it's totally flattened
I am having issues with the GL 550 this is the left side and this is the right side and
this is how the front looks see if we look at the front it's a big gap and if we go on the back see
at this moment if you look at we have a nice gap so it's working so this one is happening for all
last a couple weeks now if you see that air suspension is going up again the bag is filling up
and even while driving all of sudden it goes flat so there was a problem see now it's going down,
going down and down, and let's take a look on another side, if we look at this side
it also does the same thing, it's going up and down, I shut off the engine and if you look now
it's only 2 fingers left, this side bag has gone flat right away, and on another side,
if look at we still have a big gap. This is the tubing, this is call Mercedes Benz original it's
a line cable so this is the one we're going to replace it the air suspension bags these are new
bag so these we going to replace it and then that is the part I'm going to share with you that oh
it's an easy DIY process and let's see how we fix it, once I'm going to fully jack up then I'm going
to put the dead Jack's underneath then I'm going to pull out this jack so we have enough room to go
down once we open the trunk then you lift, open up this one and we going to take the spare tire out,
I already took the spare tire out, once we open it then you lift this one and take out the spare
tire, how it's gonna look inside 2 screws you need a Torx driver to open it you open these then you
lift it up, you lift it out and this one has one two-three and three on this side these six of
these are locking tabs you just pry it out we're going to take out all the pushpins 3 on the side
then by a couple on the back, we going to pull this carpet by folding it like this if we take
a look down here we just going to make sure to fold it, this is the one we need to open it and
this is the OEM part and we going to get a plier and put it right in the middle then we going to
open it, once it opens then it's going to come down, so this is the tubing from the airbag
and that's the tubing routed right here and then coming down that's going inside the trunk that's
where we opened it so I'm going to open it from the airbag and then I'm going to replace this one,
the reason I am replacing this tubing because I hear the air leak from this
side, I am going to open this, this is now loose and we can pull this one out so that's gonna come
out and this is the tubing right here and if we look at it now so you can see it that's going inside
of this we're going to push this tubing we need to pull the adapter out and this is the adapter
we just pull it out so once we pull the connector out so this is the tubing we're going to pull it
out so that's gonna come out just like that and On this side, we already pulled it out so we are
pulling these out just like this is the old tubing and this is new and this is the new coupling and
this is the old one I took it out what I'm gonna do I'm going to take this one-off and we're going
to insert from the bottom of the car where the rubber grommet is so I'm going to insert that one in and
we're going to push this up and then I'm going to insert this one and then I am going to put
a new coupling and we're going to tighten so let me go down I have inserted the tubing into
the trunk and as you have seen the way we took it out and that's way it's going into the same
hole as you see I inserted the tubing into this one go in this one I'm gonna go in inside so
we're going to pull the tubing from the top so I'm going to put this rubber tubing into place
once you install the coupling and this is the place we're going to tighten it and I'm going
to put it inside make sure that I tighten it right so it's nicely tightened, looking perfectly fine now
we're going to tighten on the trunk side so this is the top side we're going to insert that one
inside and this is a very important part of this tubing so once we put it in the coupling that
the slanted side has to put it inside first hand tight and hold it with a plier then we
use ten millimeters wrench and that's tight this is perfectly fine now we're going to turn
the Mercedes on and we'll see after placing the carpet back we put the wheel back and now this
cover these caps gonna go into these holes and we're going to put it in like this and we're
going to press all three gone and these are the Torx screw we're going to put it in I'm going to
tighten it that's how it's easy if we look at it now very big gap the leak is on my air suspension
has been fixed and I drove for two hundred miles and I waited a whole day I let it sit last night
this was filled in and does not go down
now it's still doing good, that's how easy we fix our air suspension leak,
it's not your airbags gone bad and it could be the tubing and I show you the easy fix,
I hope this video will help you out and motivate you to do DIY work yourself and able to fix it
