The fuel tank straps on my 2001 Ford f150 are completely rusted. Other areas have also rusted out such as the radiator supports - radiator and shroud dropped out and are hitting against the engine fan. The pick-up bed of the truck is also rusting out. Updated 08/11/11 the consumer stated when he inspected the straps, he found one of them completely covered in rust, but still in tact. Also, there was unusual rusting all over the underside of the vehicle. The entire lower radiator support was rotted out and the underside of the pick-up bed and other supports have major rust. Updated 08/12/11 the consumer stated when the support gave out the radiator and radiator shroud fell onto the fan that is mounted to the engine. Also, the ball joints and steering were wearing prematurely due to lack of grease fittings. Updated 08/30/11.
