Thanks that a start

Whats wrong with them? does car drop overnight same as the citroens do?

[goldestate]

The ride is hard or bouncy on rear it has no particular knocks and after replacing wishbone bushes, anti-roll and drop links on front oh and adjusting wheel bearings the smooth front end is let down by the rear.
No it doesn't drop down as I suppose the road springs maintain height.

 

[franey]

Give me a nod if you need some of these (new)

 

[Neebo]

If it's a knock then maybe subframe bushes (front ones)Or support joint (rose joint/trunnion bush.
if it's bouncy maybe leaking shockie
if all ok and it's hard I.e suspension spheres (not common though)Fecking around with hydralic fluid is not a nice job as it's certainly NOT good moisturiser!!!!

I hate hydraulic oil almost as much as i hate used diff oil

Self Levelling

Hi Goldestate, are you in the UK? I am pretty sure I need to do exactly the same thing as my suspension at the rear seems to be too low, possibly a joint effort?
Regards
Stuart

 

[goldestate]

The suspension spheres have little if any effect on the sitting height of my car that is provided by the rear springs the spheres are the shock absorbing part of the suspension and the things that look like shock absorbers are in fact hydraulic rams if your car sits low it may just be saggy springs.

are you sure about that?

it's certainly not the case on the w124 rear suspension.

The rams adjust height, that much is true but pressure retained in the hydraulic system maintainss the car's height when the engine is not running.

If your suspension is harsh and has little or no travel then suspect the spheres

 

[goldestate]

I am sure, on my 210 the self levelling suspension does very little until some weight is loaded then the valve shoves more oil in to correct level
my suspension is hard and my spheres have failed the oil is discoloured my car rests on its springs roughly speaking the shock absorbing is taken care of by the gas contained in the sphere seperated from the fluid by a membrane.

 

[andy_k]

if the spheres have failed - which it sounds like they have, the space normally occupied by the Nitrogen is filled with oil because the membrane will have split hence the lack of movement in the suspension.

I haven't worked on a W210 system but when you drain the oil from a W124 the rear end drops like a Citroen.

 

[goldestate]

The rear suspension of the W124 features the Mercedes multi-link axle introduced in 1982 with the Mercedes 190 and which is now standard on many modern cars. Estate cars (and optionally, saloons and coupes) had Citroen-like self-leveling rear suspension with suspension struts rather than shock absorbers, gas-filled suspension spheres to provide damping and an under bonnet pressurizing pump. Unlike the citroen traditional application Mercedes opted for a fixed ride height and employed rear coil springs to maintain the static ride height when parked

you can quote as many articles as you like

Drain the oil out of a W124 system or have the return/levelling valve fail and your car will sag like a Citroen

Based on having done the job on a few W124s, not reading from a book

E320 W210 Estate Spheres and ride heights

Hi Chaps I am suspecting spheres! My ride height seems low at the back, I measured to the ground from the underside of the top of the wheel arch today and got the following:-
Left Front 66.5cm
Right Front 66cm

Left Rear 64.5cm
Right Rear 64.3cm

So I definitely have a saggy bottom, any chance of one of you chaps with good suspension confirming that it should be 66ish all round?

Do both spheres go at ones, maybe the ride height lever has seized?
Am open to suggestions.
Regards
Stuart

Are you talking about the same thing my car has rear springs and a self levelling system it does not fall down when the fluid is let out it rests on its springs I think you are mixing up two different systems

He's not mixing it up

Although the MB system has steel coil springs, they only support some of the weight. Even at the 'static' ride height with no load, the SLS system is supporting a fair bit of weight by itself.

Perhaps the Citroen comparison is a little dramatic, but with the SLS disconnected they definately drop right down low

I've had an couple of 124 estates and a few 190 2.3/2.5-16s with SLS (springs and accumulators combines), they definately drop without the assistance from the SLS.
