So I have been converting my '85 Toyota 1-ton pickup into a flatbed. The flatbed has been on the truck for a few weeks. I just have to finish the deck and it is ready to go. Today I was poking around the frame right above the rear axle. The original overload bumpers had lost their rubber and in trying to remove the remaining steel plates the bolts on both sides of the truck just snapped off. Now I know why. I was chipping off some rust that had been above the plate and my chipping hammer went right through the side of the frame rail. Kind of like lead foil over graham crackers. It obviously rusted from the inside out.
It seems I have good steel on either side of this point. I think there are some internal pieces that were causing the water to pool inside the rail, at teh same location on both sides of the frame.
So now I have to take everything apart and grind away on the rails to find the extent of good steel and start adding some steel bandaids.
I am worried about removing the flatbed now because it is holding the front and back frame sections in alignment.
Oh lots of fun.
