Ball Joints q's
 

Well while changing my tires over for the winter, i pulled out my drivers side rim, and saw that the tread on the inner side was just bald. It was the only tire that was bald, and my friend pointed out that it could be the ball joints being weared out. Not to sure what it is but i've read before that its caused from having a bad alignment. Any suggestions? Looking to get an alignment done next week.

get your car in the air, and wiggle the whole wheel side to side, and front to back while you have someone look at the suspension while you do the wiggling. Whatever suspension ailments you have will show up.
