Description of the problem | Synopsis of problem: the frame of the tacoma was fabricated with insufficient corrosion protection, particularly inside the boxed section of frame under the midsection of the truck. The frame is literally rusting from the inside out. What happens is, as the frame rusts on the inside of the boxed section, the rust flakes drop onto the bottom of the boxed section. These rust flakes then plug the weep holes in the frame so that moisture is not allowed to drain out the interior of the boxed section, thereby exacerbating the potential for corrosion. So what is happening is the bottom of the boxed section of frame is rusting out due to the build-up of moisture and the accumulation of rust flakes plugging off the weep holes. The rust flakes are 1/8? Deep on the bottom of my boxed section of frame. Basically the bottom 20% of tacoma frames are rusting out. What is particularly dangerous about the bottom of the boxed section of frame becoming compromised by corrosion, is the bottom of the boxed section is where the bracket for the rear leaf spring is attached. As the boxed section corrodes, there is less and less material supporting this major suspension bracket. The design of this bracket must be analyzed by your nhtsa independent engineer. I strongly believe that it doesn? T take much frame corrosion to severely compromise the integrity of this welded leaf spring bracket. If this bracket fails, then the front of the leaf spring comes free, the rear axle comes out of alignment, which could cause the operator to lose control. This is a major safety issue! I also can't help but wonder that since the frame is an integral part of the vehicle's safety system, what does a severely corroded and weakened frame do to the level of crash protection offered by the vehicle? If nhtsa? S independent engineer finds that the frame does play a major role in the crash protection offered by the vehicle, then the nhtsa will have no choice but to force toyota to do a recall. |
