Will a dealer replace a slightly bent knuckle under warranty? Have less than 12k miles. Or do they consider that abuse? Or is it one of those, it depends...
You could try to get it replaced under warranty but I doubt they will. The dealer would have to get creative with how its submitted, which most dealers won't hang their neck out like that unless you're a REALLY good customer or know someone.
Is the right lower control arm completely pulled in towards the chassis? At this point it needs to be made sure the camber really can't be corrected and its just not a botch alignment job. You have to spend some time to get these trucks dialed in right; time that maybe the alignment shop didn't want to spend...
