Thats a wise idea, you'll likely get more responses that way. Welcome to the forum by the way!

My experience with SLS

Purchased an '82 euro td wagon with sagging rear - pump was replaced at some point but reservoir dry! I filled system and had some results but then noticed accumulators were shot, replaced those and voila! Also replaced SLS valve with used valve and linkage arm and adjusted to neutral position. I then measured center of wheel emblem to fender lip and noticed slow settling overnight but as I drove car, it seemed to improve. I added a seal conditioner (non petrol based) to swell any dry seals and so far, things look great! I am not a big fan of "mechanic in a bottle" but I have had several successes in the past and thought I would give this a try. I will most likely flush and refill in a few more months as fluid is over a year old and I want to see if I can maintain cleaner looking fluid as a result of a better sealed system. SLS is fairly simply but I can understand why it people run from it as components are expensive. One member sells SLS valve reseal kit with great instructions - my struts appear to be in great shape and ride is wonderful versus the drive home when I first purchased this wagon -my experience, thanks

Is it the same pump as used on the 190E 16? If so I have a used one.

It is mentioned above that the system self bleeds. Most of this talk is about the W123. Does the W124 also bleed like this? If the bleeding process is automatic with system operation, what is the bleeder on the top of the SLS valve for?

I just replaced my accumulators and am looking for what else I need to do to get the system functional.

That bleed fitting is probably there just to bleed pressure of the system in order to work on it. Same as the 123.

Hi,

I´m having a problem with my SLS.

The car rises whem fully load, everything works fine.
Except when I hit a bump or something similar. It feels hard, it´s like when we ride with bad shock in front. The springs go down but it´s not smooth.

What could it be?
Bad rubber bush? The Shock? The accumulator? The Valve?

Thanks in advance
Vasco

Accumulators. It's almost always the accumulators.

I second that.

I never really though about it before but it's funny that the same part can result in two different very symptoms when it goes bad. Hard ride or really bouncy ride. They must fail in two ways. Not sure how though.

What I've heard is when the diaphragm fails, initially the nitrogen mixes with the hydraulic fluid, forming bubbles that make the ride bouncy for the same reason your brakes get spongy when they need bleeding. Eventually the bubbles purge out and then the ride gets hard, because all the compliance is gone from the system.

I´ve check the rear axle, and found that a suspension arm is kaput.
Thank You!

W124 SLS Issues

New member to forum, was really happy to see such a complete write up on W123 SLS. While the SLS is functionally similar in W124, are the leveling valves (and repair) the same? My '87 300TD SLS jacked the rear end up as for a heavy load, even though there was no load, after only 432K miles. I read your (Biodiesel300TD) troubleshooting guide, but didn't find a "rear end jacked up and rides like shocks are bad" write up. D you have a guess as to what my problem might be? Do you have a kit for W124 valve (if that's the problem)? Do you offer rebuild service? Thanks for your help, David E

Unfortunately the 124 valves are not rebuildable. They aren't designed to come apart like the 123 valves are. You can get to some of the o-rings but not all of them. If the rear is riding high all the time I'd look at the connecting rod between the valve lever arm and the sway bar. It may have become disconnected and so the lever arm dropped down, making the valve think the rear is sitting low so it's compensating. If this is the case your car is sitting at its max height and probably riding bad because of it.
