[W126 Coupe] stock 560SEC picture

[Axel Wulff]

Tom,

Bad accumulators can result in both a hard ride and a soft and "wobbly" 
ride.

With the hydraulic suspension the accumulators are the shock abosorbers. The 
struts are just hydraulic pistons. The accumulators have a membrane between 
the oil from the closed hydraulic system and the nitrogen in the 
accumulator. When your car hits a bump the oil moves up the piston and into 
the accumulator, which pushed the oil right back.

If you are low on oil and the membrane is shot, there will be no pushback 
and the ride will feel soft and squishy.
If the accumulators are filled up with oil there is no absorption and the 
ride will be hard.

Because there are two accumulators, suspension problems due to one or two 
malfuntioning units (and they can each fail both ways...), the best first 
step in sorting out suspension problems on a car with your mileage is to 
change them both along with the hydraulic oil and filters.

If your car is still riding low after servicing the accumulators, your 
springs are probably tired and should be replaced. A perfect excuse to go 
with the H&R lowered springs. :-)



Regards,
Axel J. Wulff
