front wheels tilted

i noticed today that the front wheels on my blazer are tilted inward at the top and the tread around the inside of the tire is ofcourse wearing veary fast...i had thought that it was just the alignment but i was wrong...does anyone know how i could fix this or would i have to bring it somewhere ...seems like since i bought this blazer all i have had is problems....still cant figure out what is wrong with the tranny either

sound like you just need a camber adjustment w/ a front end alignment. any auto alignment shop should be able to fix it or tell you if there's a more serious problem. alignments only run you 25-40 bucks on the average. the tranny i can't help you with. the blazer is one big headache for me.
