I think the self level works

Typo's all over sorry.

sounds like at least 1 of your shocks are done for. A bouncy car is a symptom of knackered shocks because if they're leaking oil they'll sag, leaving the car riding on the springs. I don't think the sec had self levelling unless it was an option. A quick way to tell is to look at the top of the shock, if there's a rubber hose coming out near the top then you have self levelling, if not you just have normal shocks and can thank your lucky stars cos they're a lot cheaper (and easier) to replace.

Yea I have SLS. There is no leaking from the pump or shocks. Um and I had raised the car up in the back on the driver side (engine off) to put some air in the tire but I didn't raise it to much. Then i raised the passenger side (engine on) a lot i forgot why i did that side. now it's level on that side. P.S. the car was sitting for about a year or year and a half. Driver side was in dirt unleveled had two flats.

ok, chock the front wheels and jack up the rear end (don't forget to use axel stands). climb under the rear and look at the antiroll bar, this is where the self levelling control unit is located. it's only a small metal box with 3 or 4 pipes coming from it. There's an arm coming from the unit which should be attached to the antiroll bar. This arm is unfortunately quite flimsy and has a tendency to cease up and break. This would result in the self levelling not functioning and could leave your suspension feeling, spongy. Hope this helps..

Thanks a lot I will take a look at it.

Ok thanks alot I will take it to a dealer cause I do want it done right. And I could be riding in air I haven't thought about that. Cause its not hard at all just really bouncy and one side sits lower then the other. Car was sitting for 1/2 year on a drive, it was very unlevel plus the hole driver side was flat.
