I just bought a 2000 Silverado. The truck looks great, drives great, sounds great, etc... However, it did have a few issues that i wanted to take care of, like replacing all fluids and a bad sending unit (surprise, surprise). So, I went to the mechanic and spent most of the day there, while they were checking everything out and doing what needs to be done. The problem appeared when they dropped the tank to replace the sending unit. The two cross members, one that's just aft of the cab and one that is next to it over the middle of the tank are in bad shape. The front one is somewhat better b/c it is not completely gone. However, the one that's over the tank is rusted 75% through on the driver side. The pass. side of it carries one of the shocks, which is definitely not good, but somewhat better than if the shock-carrying side was rusted. Now, when I say rusted, I mean that there is a huge hole in it on one side and multiple smaller holes on the other. The only way it can be fixed is by cutting it out completely - frame rail to frame rail and welding in a new one. Now comes the question. Has anyone had this happen? How was it resolved? Can it be resolved? I looked at the parts diagram at a collision shop next door and they do not list a separate cross member. Is my "new" truck a total loss? I did some search on the i-net and haven't found a solution. The only thing that comes to mind is to find a totaled frame at the junk yard and cut the good cross members out. Please help! Thanks in advance.
