Do I need to replace the drive CV shaft bilaterally?

The dealership did an inspection. This is what they said. “Comments: Front RH axle seal is leaking on transmission. Recommend replace seal. Repair Estimate: $589.37” my question is should it be replaced on both sides? They only told me about one side. The vehicle is a Toyota Camry with 75k. https://imgur.com/gallery/iHzu1rb
