So I have noticed that my front tires tilt inward. I am not sure if this is an alignment problem or my upper ball joints might be busted... I have had several alignments done on the vehicle, but I can't eliminate the tires from tilting inward like these pictures. Could it be a upper ball joints? I noticed when i was replacing lower ball joints and a front drive axle the underside of the upper ball joint had a small chunk of metal missing. I am not sure which side it was though. I have jumped the truck several times before. Here is the pics.
