Front end steering problem

In june I got into a small Collison with a tow dolly/car hauler. My truck was the only one damaged on the front passenger side. Lights still work and tire/brakes was not damaged. But the very next day I had a BAD need for a alignment. Went and got that done but I needed another alignment literally less than 2 months later.
What parts do you think are damaged and could have caused this?
Any one else having similar problems?
Any suggestions welcome and there is not a price on parts since I'm currently replacing most of the mandatory parts. (Radiator/Full front and rear brakes/Headlights) etc.
Looked under neath and nothing looks broken but will take another look if needed.

 

We like pics to help form opinions here. Your alignment numbers might help as well.

 

Check the poly bushings on the steering rack for wear and tear. Also the lower control arm bushings. Do you know what is going out of Alignment? Cam, toe, caster?

 

Ok will show pictures when I get back home.

 

Will look again when I get back home to make sure. My apologies
