Thanks to Jim and John for a perfectly good diagnosis - my PS pump is in
fact *quite* loose (I think partially due to a good soaking in oil from
having a loose and then detached vacuum pump... Imagine that!).
As soon as it's dry and I have some daylight at home, I'll contort enough to
tighten it up. For now, guess I'll keep driving the truck. I'd hate to have
ANOTHER engine-mounted pump fall off.
