roy, SLS = Self levelling suspension. Birdguy, check your rear springs for broken coils and check the sls link in the centre of the rear anti roll bar is still connected. If these are ok then you'll need to check the suspension globes in the boot, they can be found behind panel at the back of the boot. Undo the 20 or so 10mm bolts and pull the panel out of the weay. There is no way to manually adjust the individual shocks and one side being lower than the other would suggest either a knackered globe or a knackered shock. DO NOT under any circumstances try to repair a faulty shock yourself as the system mercedes uses is under immense pressure

Thanks alot Mick I will check these things out rite now..


The 560sel and SEC had hydraulic rear self-leveling suspension that few but Mercedes are willing to work on. Over time, the hydraulic balls in the rear fill with fluid as the seals age, resulting in a harder and harder ride. Unfortunately, you can NOT swap them out for Bilsteins or the like - they must be repaired by a dealer or REAL Mercedes expert.


I'm totally in agreement with (535) Mr. RicKELake, I was told from one of the Mercedes Dealers that one of my cams are not working properly and that they cost about $150 each... My vehicle has been sitting for about 12-14 years, I believe that my reservoir is contaminated with h20 over the years and the hoses is old,dry, crack and leaking. I'm going to first start out drain the old fluid and replacing the hoses, there's a bar which control the hydraulic at the rear and which I sprayed WD-40 on and it's working pretty good, will keep you updated on my result, if anyone has any suggesting on what my problem might be, Feel free to drop me a line or

    I don't the my 560sec is self leveling. It's really bouncy in the back. Could it be bad shocks or spring? Or has the self leveler token a dump on me :-(. P.S where do I check the oil for that?
