Also the rubber impeller was dry and relatively hard. I
have a volvo shop manual and it says that the impeller should be lightly
lubricated with grease. There was definitely no lubrication left on this 4
year old impeller.

The grease is to aid in re-assembly. With all the water flowing through
the pump, the grease will be gone in minutes. Don't worry about greasing
your impeller other than for initial assembly.
