I have a 1990 Chevy Celebrity station wagon that has a power stearing leak.
I've isolated the leak to two things.  The pump high-pressure hose is bad
(squirting here and there, and everywhere), and the driver side boot is also
leaking fluid.  Should that boot be leaking fluid, or is it just a dust
cover?  If it shouldn't be leaking fluid, does this mean the internal power
stearing gear assembly has a bad seal.

I noticed they have a crossover tube between the right and left boots.  Is
this to allow fluid to transfer from one to the other?  If so, then it
sounds like it's normal for the boots to contain fluid.

Thanks,
Don
