Please help ball joint question
 

I just got a 2007 cx7. I was told it needed lower ball joints. I ordered the ball joints online. Then when i trued to look up changing them. It looks like the whole control arms get replaced. Is it safe to press out old an in new ones into the arm? I really need this car on the road. If anyone can help me please reply. Thanks

Yes it is....
 

You can buy the c type clamp and adapter pieces to go with it. You can press them in or out on control arms. Usually only once. After going through the second pair. The socket where they sit in can become stretched if done more than twice. Then you'll wanna replace the control arms. But yeah their meant to be replaced at least once.

Few months ago I had mine replaced for free. https://www.cars.com/recalls/mazda-cx_7/
