I've noticed that when I'm at full lock (turning left) my steering wheel is at an angle of 45degrees like this \ but when I'm turning right (full lock) its straight up and down like this l . I'm pretty sure it had the same amount of turns to go from lock to lock until I spun my car in the wet last month and mounted a curb. The alignment is still ok but why can't I turn the steering wheel all the way to the right? I hope you's understand what I'm saying.

You may have bent something in your steering linkage, like the tie rod perhaps?

It might be the stops on the lower control arms, 1 might have been damaged.
