Well, I thought I had my SLS all sorted out on my '84 wagon, new accumulators, high pressure line, return line, fluid flush and fill, new z links, adjustment rod, pump confirmed as good, etc. Yesterday, I noticed that my passenger side appeared to be lower and sure enough it sits at 12.5 while my drivers side sits at 13.5 so passenger side strut appears to be slowly losing pressure internally over night as I cannot see any signs of external leaking. I have not checked upper hose connections on struts but I would imagine if these were even just slightly loose there would be some visible leakage(?) Has anyone on the site ever discovered that their upper hose connections were loose and that made a difference? I will check these connections today - Thanks again -hate the idea of buying a new strut and if I have to, who has the best price of these very expensive struts? THANKS!
