Inside wear can also be attributed to too much toe-in or toe-out.
In fact, improper toe will wear the front tires down quicker than improper Camber angle. Bad Camber takes a while to materialize in the tire. Bad toe can happen in a few thousand miles if it’s severe enough.

Given the car is 17 years old, you’ll want to check the condition of the bushing and put a pry bar on the arm to see if there is excessive movement
