My 2001 Toyota Tundra sr5 4wd. Access cab pick-up truck has a rusted out frame. My truck broke down on the highway(may 1st) I towed it to my mechanic shop. My mechanic replaced an oxygen sensor that had rusted away on the exhaust system. Further inspected the vehicle and said it had extreme corrosion (rust) on the frame, brake line connections, suspension mounts, exhaust system. . . . "rust everywhere". He suggested it was unsafe to drive because the brake line connection points were so corroded (rusted away) that they could fail while in operation.
