Carrier/rack problems of the 2008 Dodge Caliber

I did some work on the front end, I replaced tierod end and ball joints,also put new tires on the car. I was scheduling an alignment when the front would make a pop sound and a slight snap when going over bumps and when the steering wheel is turned to the left. I looked to see what the matter was and the sub frame was cracked and rusted. . . I wash the car 2 a month especially in winter. The sub frame also connects the swaybar, struts and it cant get aligned due to the broken frame. . All too prematurely.

Driving down the road and making a righthand turn, I heard a loud pop then the car started pulling hard to the right. I had to decrease my speed to 25 mph due to the severe pulling. Had dad look at car and found the sub frame was cracked in half on drivers side. The car has not moved at all since that was found. My 3 year old daughter is often in this vehicle!.
