Hi guys

I have an '86 Cossie with droopy rear suspension and want to know what I need to check to trouble shoot the system. No leaks at any junctions I can see, either in the 'shocks' or the pump. Fluid reservoir is full.

I've had the car for around 6 months, bought with a FULL MB dealer service history and one owner from new, so, aside from the stiff rear end it's a good 'un!

Any ideas?
