What kind of system can I use to replace an old hydraulic system which is mechanical What components can be used in replacing hydraulic suspension system?
not all touring diesels came with leveling system if yours is so far gone it can't be fixed your best bet is to either purchase a clunker and swap the suspension out or purchase what you need from a salvage yard. at minimum you will need the springs and normal rear shocks from a 123 bodied sedan.or wagon
You could do what some people did with their 560SEL sedans. They took out the hydropneumatic self-levelling shocks and installed the regular shocks found in the 420SEL sedan. You could try installing regular shocks from a 300D sedan but I don't know how well they will handle the additional rear-end weight of the station wagon though.
