Is the purpose of this thread to save money to reapir the SLS or is it that the SLS is a problem area that in not reliable or has a short life?

Thanks

Hey, Ken Downing, can you give some more info. re: rubber pieces for rear springs? It seems probable that failure of the hydro. system is due in part to the failure of the springs. As the springs do less of their job, the hydro. system has to pick up the slack and suffers from the effort. Before I start rehabbing the hydro. system, I need to be sure that the springs are doing their job. The most efficient and affordable solution so far seems to be to get the larger rubber piece installed. So, I'm wondering what the part number is and where in the world I would locate these dudes. Thanks for making a very cloudy picture a bit clearer.

Don, no, there is not a site in the USA as far as I know of - however, MB just opened a new site... not sure if it will have pricing though (subscription required) : http://www.startekinfo.com/StarTek/ Note that the Euro site will at least let you know that the part is still active & orderable, and give you a rough idea on cost, since Euro dollars are pretty close to US dollars (presently).

Mccan, the rubber shims above the spring are to compensate for longer/shorter springs (red/blue color codes) for the same part number, OR for vehicles with more/less options. If your car has one of the thinner pads, you could install a thicker pad, but it won't make a big difference - about 1/4 inch in ride height. There are only 3 thicknesses available in the rear, but 4 in the front. They don't squish down with age, but they do get hard. And yes the hydro system supports some load at all times, at least on the newer SLS systems. Pull the shocks out or disconnect them and watch the rear sag with no load. The shocks just support *more* when a load is applied. The part numbers are all in the EPC (dealer part catalog), available on eBay cheap.

Thanks, Dave. Is there anything else that can be done to stiffen the springs? Maybe inserts? I have corroded steel lines and possibly more problems than that . At least the pump works. So if I am going to rehab. the hydro. system, I want to be relatively certain that it won't be overworked and prone to another failure.

I am surprised to learn that fitting conventional shocks is so difficult. I was under the impression that this was a common fix and not technically or financially prohibitive. Apparently not so. Actually, there hasn't been the first person to chime in with a success story about making the switch. Perhaps we should run a survey...

mccan, well, the best thing would be new, possibly stiffer springs. But damn they are pricey! (see my previous post with prices.) Inserts, well, yes those would alleviate sagging, as long as they stay put - some of those things like to pop out. I don't recommend this in general, but for a real low-budget fix, it's worth a try. If you get the rubber inserts and they work well, you may need to replace them every couple years as they break down & compress (don't ask how I know this.)

And yes, I think a survey would be great! You have a point, nobody has come forward with a success story. Hmmmmm. I think you could make the car ride OK with the SLS removed, provided you never carry more load than a couple passengers in the rear. Otherwise I think - just my opinion here - that the rear would sag rather annoyingly?


Best regards,

SLS blues

I will be converting an '85 300TD wagon to non SLS in the next few weeks. I have never done this before, however I have put a lot of thought into it. I will document all of the nessecary steps along with parts used in the process and will post back here when finished. I will also take some pics along the way. These SLS systems are a real pain and I intend to provide a solution. Be patient SLS owners! Help is on the way!!!!

I love my SLS. Matter of fact, I love both of my SLS'sssssss......
If they are a pain then they simply haven't been fixed correctly. You can't ask for anything much more mechanical.
Good luck with your project, and we'll look for the pics.

The only (claimed) advantage to removing SLS is saving money. The system works fine when the components are functioning properly. Most people don't want to pay for new spheres or spring legs, or figure out how to adjust it correctly...

AMEN. I too love my two SLS wagons. Hauled the wife and three kids with four large suitcases down I-95... rode like a dream. Head across state once a month in winter to the folks with similar loads and love it. 800 pounds in the very back? no problem. Find the head and fix the SLS.

Dont think you'd save $ in the long run by changing the SLS out... if you can me and others would love to hear about it.

Regards,

I do not know if this is available for the w123, but I had a Volvo 245 Wagon a few years ago, which did not have any form of SLS, but it came with something called progressive springs - i.e the rear springs became more stiff, or hard, as more load was put on them, keeping the car reasonably level even with full load.

But if I was you, I would still fix the SLS system instead of going through a lot of hassle to find and replace a lot of parts in the rear suspension, because you will end up with a much better and more stable ride in the long run.

SLS to be or not to be

Just a couple of weeks ago there was a TD in the Chicago area for sale on ebay that had been altered by removing the sls and installing heavy duty springs. This being done to support a very large wvo tank. Ill search past auctions and see if I can find it, but at least we know it has been done.

When I was in a dealership in Canada, the service advisor told me if the SLS goes bad, there are regular shocks which can be installed. The cost was about 300 CN at that time about 2 years ago.
Do not think US dealership want you to know this. The three dealers I do business with are more interested in selling a new car than fixing a old MB wagon.... Higher profits and few teck people know a plus 20 year old car or diesel

Wouldn't a 12 volt hydraulic pump of some kind work in place of the one on the head?
