My 2003 Toyota 4 runner sr5 was swaying back and forth at speeds up to 35 mph something is wrong thinking maybe the sway bars so took it to a mechanic and after he drove it and put it up on a lift he was frightened on how much rust and separation on the frame especially the rear passenger side right next to the muffler complete separation and then you walk to the middle any day now that would have separated . I was told to to have a tow truck take it back to my house which is about two-three miles away which I did but now it sits in my garage - and with only 139,000 mile on it not able to drive or sell unless its for junk.
Excessive frame rust, especially at rear area of vehicle. Body mounts disintegrating at rear. Other attachment mounts (for example rear anti-sway bar) are rusting severely. Rust noted 11/2/2018 when vehicle was in the air for service.
Noticed the right front wheel making awful sound. I had my mechanic to take a look. It is the wheel bearings going out, but then proceeded to tell me that the rust is so bad underneath that all the hose lines will have to be replaced. Brake lines leaking, transmission line leaking. All will have to be replaced. The rust is eating away underneath the car like cancer. No stopping it. The sway bars are rusting into as well. Our mechanic will let us know how much it will cost to repair the lines. . . But is it worth spending the money on??? this is our 7th Toyota that we have owned, always taken excellent care of vehicle, and I have never experience such a rusty mess. Love my 4runner but really don't know what to do with it!.
The rear sway bar and axle have rotted out. The sway bar dropped to the ground while driving and caused the vehicle to lose control.
