2005 Toyota 4RUNNER suspension problems

Filed May 14, 2026 · Body, Suspension · WA

I have a 2005 Toyota 4runner with frame rust that has caused everything under my 4runner to rust. Toyota knows these frames have problems with rust and corrosion and have done nothing, I am far from being the only one with this complaint or problem. It is up for inspection anytime. I have taken it to get work done at shops and been turned away because of the amount of rust on all bolts, lines, all metal under truck causing it to be a liability. I cant even get my skid plates off to fully address the issue. The metal is starting to split on the main frame by the tire, it is rotting from inside. Rust has always been there but last couple years has gotten really bad. So much rust my gas tank strap has broken but so much rust I cant get the skid plate off to fix it.

ENTIRE body frame has excessive rust, holes, and cracks. It is available for inspection. Toyota dealership says it is safe to drive for now but it is failing. I feel any cracks, rust, holes, separation of frame components places all occupants and anyone near the vehicle at risk for when anything fails - this could be when the vehicle is on the expressway in motion (such as when the GM ignition switch failures happened), causing catastrophic loss of life, injuries, and damage to all. It's not a matter of "if" it happens, it's "when" it will happen. There are no warning lamps, messages, or other symptoms of the problem. The exterior, interior, braking, engine of the vehicle are in remarkable shape so it's very misleading. There are also 4runners on dealership lots that have significant rust, holes, and cracks in the frames that the dealership does not warn about, rather, they still have high for-sale values because the vehicle looks good otherwise.

Excessive frame rusting. There are holes in the frame from rusting. At this point in time there isn’t anything I can do about the issues. Frame is unrepairable.

Frame of the vehicle is showing rust corrosion. The frame are the same as the tacomas that were released the same year. The tacomas were granted frame replacement by Toyota but 4Runners weren’t. Noticed a lot of other 4th generation 4Runners are having the same issues.

My frame has rotted through, causing the rear bump stops to fall off, putting excessive wear on both frame and suspension components. In parts of the frame, it has rotted all the way around and caused a loss in structural integrity. Worst of all, there is a hole near the rear most strap holding the gas tank to the chassis, which is a risk to not only me and my pregnant wife but others driving on the road around me if it where to fall off. Looking at the body, there is no rust or corrosion. The same goes for the engine bay, the rust is entirely located on the frame. Mechanically, the vehicle is in excellent shape. It has now got to the point it will no longer pass a NYS inspection.

Vehicle’s frame and suspension is showing major rust prematurely forming from the inside-out of the frame causing visible weakness in the structure of the frame that could cause engine or other suspension parts to fall off the frame of the car due to improper treatment of the frame. If I were to get in a car accident I don’t see the frame holding it’s structure. I would I highly suggest to have a safety recall done with frames with such damage.

Brought the car in for an alignment and I was told they couldn’t do it because of all the damage to the frame from rust, parts of the frame are not even there anymore, the front row hooks are gone, they said that all this damage ca impact the handle of the car and that it can’t be properly aligned and possibly won’t pass inspection.

Upon recent inspection of my vehicle, it was noted that the frame is severely corroded and rusted to the point where collapse or breaking of the frame is possible while driving. Apprently the frame was not properly treated for rust protection and can now be unsafe for driving. Enclosed are pictures of the rusted frame.
