Only that it's a common problem ;)

There's a very good discussion of this on Chris Miller's website:

His repair index is a treasure trove. In particular, he has good discussion
of rebuilding the pump -- see Section 48, Steering on this page:

Note in particular the discussion of how the pump goes together and the
necessity of ensuring that if you do disassemble it, the mating surfaces are
not warped when you put it back together! It's not an incredibly robust
unit, as everyone who has one of these babies knows! ;)
Let us know how the servo swap goes.
