the inside of the front tire is wearing and is almost flat. while the outside still has tread. I think the same happend on my truck and it was the upper ball joints. I think I need and alignment also. any help would be great thanks

 

Start with an alignment and go from there. Most likely an alignment issue.

 

negative camber if you're lowered

 

if you still have stock springs your car could also be lowered without you doign anything

 

off the top of my head ...
1. out of alignment
2. worn out struts
3. bad tie rods and ball joints

 

Not rotating your tires?

 

check your tension rod bushings
