Frame Rust Problems of Mazda B4000

My frame is completely rusted out. I went to get the truck inspected and my mechanic said the frame was very thin. He said that it may not even last another year and that next year if he does inspection the frame make break while on the lift! I live in maine and have taken care of the truck, washing it regularly. Seems like other people have had the same issue. This is unsettling. The truck is is in great shape otherwise. I wish I could get more miles out of it. Seems like such a waste. . . . . Only 97,000 miles on it.

10 years in northeast pennsylvania have caused little to no rust on 3 other Ford vehicles in the family, but my truck got hit with an extreme case of rust. No major offroading or mudding, no jumping/abusing the truck whatsoever. Toyota recalled the frames of their pickups, and I *believe* that Ford got their frames from the same steel manufacturer. I speculate that steel manufacturer, and/or Ford, did not "dip" these frames in any anti-rust formula. Frame rust/rot/cracking on a 1999 Mazda B4000 4x4 (the truck is/was made by Ford, 98% the same as a Ford ranger). Rear leafspring shackles fully corroded and extreme rust around sparetire carrier. Seems to be a problem with the late 90's - early 2000's rangers. New rear leaf spring shackles were added in place of the rotted out shackles. Frame was welded on 2 different occasions at rear upper shock mount where frame cracked. It is now cracked again. The truck has never been through any abuse. It's been primarily a highway vehicle in the family.
