Do trailing arms go bad or is it just the bushing?

I had a shop look at my 06 5 and the guy is telling me the trailing arm needs to be replaced.

I think you can change out the bushing but going through the shop, changing the complete arm is likely less expensive (less labor).

Thanks. Also after some extensive research seems like bushings are not sold separately
