Take a real good look at the rest of them. You might be better off replacing them all while you’re at it. Yep got the whole back line replaced. Even though it was the back driver's side, the back passenger side was pretty far gone too. You're drivin' along, you're drivin' along, the kids start shouting from the back seat, "I gotta go to the bathroom, Daddy!" "Not now, damn it!" Truck tire. EEEEEEEE! I CAN'T STOP! There's a cliff! AAAAAHH! And your family's screaming, Oh my God, we're burning alive!" "No! I can't feel my legs!" Here comes the meat wagon. And the medic gets out and says, "Oh my God". New guy's around the corner puking his guts out. Do you validate?
