hey guys, Thanks in advance for your input.

I have a 1981 300td and love it... however it currently is suffering from a crazy bouncy rear end (inflatable bounce house status.) I know that this is a common problem but before i order parts i wanted your input....

the rear of the wagon bounces like crazy driving down bumpy roads... when parked, with the engine off you can bounce the rear of the car (by jumping up and down on the rear bumper) and it continue to bounce after you step off the bumper.... The SLS seems to work, and if you manually manipulate the leaver it will raise and lower the rear end without hesitation.

as far as i can tell there are no leaks in the sls system, and the fluid in the reservoir is at the correct level.

from what i can gather the accumulators need replacing? and while im at it would you guys suggest replacing anything else?

-as a side note i am running on straight vegetable oil via a two tank system. I have over 10k miles with no problems at all. My 2nd tank is located in the spare tire compartment so i have more weight than usual in the rear...despite this my other mercedes diesels (sedans) handle wonderfully, and i see no reason why the wagon should not as well..

thanks again!
