Hey all, I am new here and have a question. My vacuum lines are bad and have caused damage to my plastic hub. I thought my bearings were going out from the sounds, but it was the hub trying to engage and disengage on the drivers side. I have decided to replace the pvh with the avm manuals. So, I will still have the cracked vacuum lines pulling air. Do I just leave them alone, tape them up, replace them? I don't know if I want air or whatever constantly being sucked through the leaking lines, but I bet you guys do know. Ay advice would be appreciated. Thank you. 1999 super cab, sport, 4x4, 4.0, standard, 4w abs.
