A ten year old truck and there are questions on what Might be worn ?
It's great that people on here try to help with issues , but they sometimes overlook the big picture.
In a nutshell , the OP has worn out suspension parts .
We all can try to diagnose which ones they may be .
But it is rather difficult to wiggle a wheel from behind a keyboard a few hundred miles away and say "OH ,it's a ball joint"
To the OP:
You may be better off enlisting the help of some nearby members or mechanics referred to you by someone you trust who can do a "hands on ".
Archimedes screwed us !
I knew a blonde dyslexic agnostic insomniac - she'd lay awake at night, wondering if there really was a Dog.
