I want to know if I need to replace both axle (CV boots) In my 2005 Honda accord?

-I am being charged 400.00 for parts and labor. 118.00 each axle. I am wondering if I need both replaced? When I turn to the right I hear the clacking noise. But when I turn to the left I dont. Will they just replace one, or is it better to replace both?Personally I would just replace the bad one
Kinda hard to say without seeing it but I'd say better safe than sorry.
