My car's Front Subframe Crossmember is bent on passenger side. Mechanic suggested to change control arms as well. Should I change the control arms also?

Would like to know symptoms of bent crossmember? Driving is not comfortable for me. I am uncomfortable that my car is not absorbing any suspension. When tires move on gaps on bridges/small pot holes/uneven roads I feel like tires hitting something very hard. Is crossmember bent causing this? Appreciate any help.

Also looking for Front Subframe Crossmember for 04 G35 Coupe Base. Please let me know if anyone have it. I live in Sunnyvale, CA (94086).
