1997 Honda Civic Axle needs replacing too soon?

In February of 2008, at 130,889 miles, I had one of my front axle shafts rebuilt in my 1997 Honda Civic.

In March of 2009, at 142,392 miles, the same mechanic told me both my front axles needed to be replaced.

Did the one they rebuilt wear out too quickly? I don't want to pay for something that should have held up longer. I know it's not under warranty, but I will take it somewhere else if it was not done correctly the first time.
