HYD. suspension question

I have a 88 300TE and rear struts are due to be replaced, can i disconnect the load level system with out any bad effects to handling or anything? reason i ask is it works when it feels like it and have sent to shop many times for the mystery problem and can never get a straight answer from the local benz dealer about what i asked. thanks for any help offered and i have learned so much from this forum. I have found that this car is a much different monster than my Porsche 928. anyways thanks for help offered.

RE: HYD. suspension question

Probably, The system is pretty straight forward. The engine driven pump drives hydraulic oil thru a pipe to the rear axle, the valve is connected to the torshion bar via a arm. AS the car settles the valve opens and allowa oil to flow to the "spheres" which are canisters containing a diaphram and the other half is filled with nitrogen. The oil is fed thru a hose to the hydraulic "struts" they are not shocks and ccauses them to extend which raises the level untill the valve closes and routes the oil back to the reservoir and pump. The spheres go bad around 80 K the struts go bad when they leak or their bushings go bad. The (2)spheres should not go for more than $300 at a good shop installed with oil flush, MB little higher. The struts are $400+ each and are not more difficult than shocks. I have not heard of too many valves or pumps go bad, you can disconnect the valve, and the car will sit a little lower due to no redidual pressure in the rear. There have been some who replaced the "struts" with regular shocks and by passed the valve since it is a loop system. I dont know if the 88 used a tandem pump with the PS, just dont let it run dry.
