Andrew, if the SLS oel is that dark, drain it, take out the reservoir 
and clean it.  then fill with clean fluid and bleed the system.


I always changed the fluid every time I was in the system, like  for 
changing accumulators.  I don't know what the book says, but i'd drain, 
flush and put in fresh oel every 2-4 years at least.


Most of my wagons came with SLS problems, so pretty much I did that when 
I got em.

Take a turkey baster and slurp up a bunch of the oil, put it into 
a bowl and see if it is indeed black. More then likely it will be 
a clear slightly brown oil color. That is what mine was but in 
the tank it looked black.

I just happened to check my SLS fluid today, and to my horror the
suspension oil is black. What does this mean? Do I simply need to change
the SLS fluid,, or is there something wrong with the pump? I have a 123 300
TD same as yours.

Yep. Drove up to the library and the improvement in ride was 
definitely noticeable. Well worth the cost and the 2 hours to do 
the job. Next is the o-rings and seal in the pump. Will be 
picking the ones from MB up tomorrow. The other two I got when I 
was in town yesterday.

I like to bleed the system by loosening the flexible hose connections at
the top of each strut, which is where all the trapped air will end up.

So for a couple of months or more I've been noticing that the rear end 
of my 83 300TD has been going up and down a bit more then normal when 
going over bumps. Not too bad but kind of like when the shocks are not 
too new any more and may need replacing.


About three weeks ago I noticed that the oil in the SLS tank was a 
little lower then half way so I put in enough to fill to Max and 
checked for leaks, of which there were none, so I said good to go.


Last week I checked the oil in the SLS tank again and found it down to 
Min or a bit below. No leaks. I dithered a while and on the 5th I 
ordered new accumulators from Parts Geek. They got here yesterday. Not 
bad shipping time.


Today I got under there and put a hose on the bleeder and let the oil 
out. WOW! So much gas in it that at first it looked like oil with 
water it was that white. About 3/4 of a quart later it stopped.


Changed the accumulators and checked the old ones. IF one was to go by 
the old way of checking by just pushing a little wood dowel
into the hole and see where the plug in there is one would assume that 
everything was good as the plug was right there about an inch or so 
in. Just like the new ones. Not satisfied I took a steel flatface 
punch that fit into the hole and pushed down on the plug. Don't do 
that at home. I almost got a face full of oil that squirted out of 
there. In other words there was still enough pressure in the gas bag 
to push oil out with an opening force of less then 75lbs or so that I 
was applying to the plug. So while they were still working, sort of, 
with the help of all the gas that had leaked out into the lines and 
struts, they were well on their way out.


On the new ones BTW I could not move the plug at all by pushing on it. 
Makes sense since there is somewhere around 400lbs or more of pressure 
in there.


I guess this confirms that if you have to suddenly put a lot of oil 
into the SLS tank without seeing any signs of a leak then you might 
want to check what the oil looks like coming out of the bleeder on the 
leveling valve. If it has a lot of foam then send for new accumulators 
because the ones you have in there are bad.
