Maybe, although I've only heard that noise starting from Friday and at no time at all beforehand... I have an irrational fear of the pump running in a vacuum and auto-disassembling at high velocity
If you fill the fluid level to the top mark with the engine off (for more than an hour or so), then run the engine for a while and stop it for an hour, does the level rise past the full mark.
If it does, then replace the accumulators, as they are taking on fluid.
