Is replacing front compression bushing necessary? on 2006 Honda Odyssey

I have not experienced any noise when going over bumps, or having unstable steering wheel issues. But Honda service adviser told me that the bushings were cracked, if I don't have them replaced it can cause many subsequent problems. --the catch here is you can't just replace the bushings on this model, you have to replace the whole arm. So the part cost is not $20 but $330. I just spend $900 to have the control arms replaced as Honda advised. I want to know if the replacement was necessary.
