I'm ready to give up maybe you guys can help figure out this problem. The truck is a 2001 F350 diesel, the problem is everytime that I start to brake heavy or when I'm towing my trailer the truck wants to pull to the left the more weight the worse she gets . I have just rebuilt the whole frontend (balljoints,u joints ) and just redid the the whole front brake system (hoses , pads , calipers , rotors) but it still pulls to the left. Do any of you guys have an idea what the H is causing this ? And I did have the frontend put in line . This really sucks , can't haul my camper to go to any of the shows.
