i was checking my berake pads case i heard a little squeel, turns out they are fine, just a little dirt in there. however, when i was checking the frone, i noticed that the dust boots on the ball joints on top and bottom control arm, on drivers and passengers side wewe broken, ooks like they exploded. so i have 4 ball joints that the dust boots are gone from. my question is i dont feel anything wierd in the suspension or anything else, so i dont think the ball joints are bad, how long will they last like that, estimate, the answer "not long" will not help me. thanks.
