first, you probably want to make sure that what the lower control arm bolts to hasn't moved.

Jack the car up, and measure as precisely as you can parallel points on the left and right side of the car, from some rear suspension member to
a mounting bolt of the control arm [where it mounts to the body]. It should be within a 1/16 of an inch [or 1 mm if you are in Canada!].

You also should check that it hasn't twisted [one bolt hole is further out than the other].
I believe the distance between the front two and the rear two mounting bolts should also be the same.

If it has, you probably will want to junk it, as it generally is expensive to get a unibody frame straightened and if you don't the car won't
handle right.

As for actually repairing it, the cheap chilton/haynes repair manuals you find at your local parts store would have the procedure, as it's pretty straightforward and common.

If you got a curb hard enough to damage a control arm and knuckle, step one is to take the car to a good body shop and have the cradle/unibody inspected.

For future reference, Chiltons/Haynes manuals are more useful as door stops.

After reading the title I thought this was going to be a medical thread and was ready to move it to the lounge. :)

Oh it is? So you have the equipment to check it yourself or you took it to a shop?.....

FSM or try the tech tips section. These are pretty straight forward bolt on parts. The control arm to cradle bolts must be tightened with the weight of the car on them, at ride height.

Took it to a body shop that used my recent alignment to do some type of measuring. Thanks for the info but what do you mean I have to use the weight of the car to tighten bolts

"With the weight of the car on them". You can't use the weight of the car to tighten them. You tighten them to spec with a torque wrench, while they are installed on the car with the wheels on the ground.
