The dust boot on my balljoint is torn, is there anyway to replace the boot. A-arm is stock.

 

nope, you need to buy a new a-arm if you want it fixed. the a-arms actually aren't that expensive. my buddy had the same problem and he is just running that one with a torn boot. he hasn't had any problems yet. i don't remember if his was an upper or lower a-arm though. but, it wasn't too expensive for a replacement compared to the aftermarket ones.
