Chassis/frame on 4th generation 4runners have a severe rust problem. many are documented & discussed at http://www.toyota-4runner.org/4th-gen-t4rs. similar trucks in toyota's product line qualified for frame replacement but the 4runner was ignored. the rest of the truck is 100% rust free except for the frame. recently had a body shop look at the frame - was described as "too rusty to weld onto" when discussing patches. below i am asked for a date when this event happened. i am putting todays date, 2003 because logically the truck has been rusting since it was built.
The frames on 2003-2008 4runners rust very badly and have deemed hundreds of otherwise good vehicles unusable. note that just the frame components are rusting through while the bodywork remains intact.. toyota recalled and replaced frames on several similar vehicles in their lineup but did not offer the same to 4runner owners. hopefully this changes.
