My '85 Westy has started leaking what I believe is power steering
fluid.  It's coming from the passenger side of the assembly. Before I
make matters worse does anyone have any ideas on likely causes and/or
solutions?

        I've checked the reservoir and it's still above the minimum mark so the
leak has not yet been enough to change that.

        Thanks in advance,
