The frame on my 2001 Ford Ranger has completely rusted through just in front of the rear springs on the drivers side. The truck only has 80,000 miles on it and is otherwise in excellent shape. There is no rust on the body. It is now unsafe to drive.
I attached a yard trailer to the receiver hitch and as I pulled out of the yard the hitch pulled right off the back of the truck. I looked under the truck and saw about a foot of the rear frame rails were completely rusted away on both sides. Both rear leaf spring mounts were broken away and the springs were pushed up onto the bed of the truck. This truck has less than 60,000 miles on it and no apparent rust. If this had happened on the highway the trailer would have gone sailing down the highway possibly causing an accident. Both rear springs detached from the frame and if I had been on the highway, there is a good chance I would have lost control of the truck.
2001 Ford Ranger was taken into auto shop for routine maintenance. The mechanic inspected the vehicle and found the rear spring shackles and the frame rotted and about ready to fail completely. The springs were found to be pressing up on the bottom of the frame. Also noted bumper was about ready to fall off. All of this due to severe corrosion of the frame. No maintenance was performed on the vehicle and a recommendation from the mechanic to remove the vehicle from the road was advised.
Went to rear of truck and found bumper had broken free on the drivers side. Looked under the tuck and found that the entire frame in the rear is rotted and the leaf springs are in danger of coming completely off. The bumper is entirely free from the truck. The passenger side of the frame directly over the tire is cracked completely through. This is the worst frame I have ever seen and have lived through the 70's american car manufacturers mess.
Rear wheel assembly (wheels, axle, leaf-springs) became detached from frame due to severe and premature frame and leaf-spring bracket corrosion (failure caused abrupt pull to center of highway at speed, fortunately no accident, since I am a pretty good driver). Subsequent inspection revealed extensive corrosion associated with vehicle frame and critical suspension components. Leaf spring brackets and various other suspension components noted to be manufactured from ultra-low carbon steel (known to turn to dust when exposed to weather). Vehicle is a 2001 with only 113,000 miles; truck is basically junk at this point with no chance of replacing the numerous components effected. I replaced the leaf-spring brackets; however I am fearful to drive the vehicle since it may kill me. Good job Ford instilling customer safety, satisfaction and quality engineering. Hope the few bucks you saved by using sub-standard materials on critical suspension components was worth it. I guarantee my family will never purchase another Ford product. -husband, father of two. . .
