How much play up and down is there in the axle where it goes into the trans?

This model trans is notorious for differential carrier bearing failure, if there is a lot of play, the bearing is most likely gone.

I have one '98 V6 coupe (a customers) that I change the left axle seal monthly as it gets torn up by the axle drooping down. They won't replace the unit until it completely fails (this has been going on for 40k now, car currently has 153k on it)

Your car should have a warranty extension good for 7 years, unsure of the mileage, for carrier bearing problems. Check your vin with Honda to see.
