I have a 2004 4Runner Sport 4.7 V8, and I can't find any rust anywhere. My wheels (including the spare) are aluminum. I live in Colorado. Maybe I'm just lucky.
I have a 2018 4Runner used in Florida only, and no off-road driving.: Spare tire started rusting after 1 year. Refinished. I go around the entire vehicle periodically and hit anything starting to rust with rust oleum "rust reformer". (A decent product) I have a 1999 also which is mostly rusted out beyond repair, but it was up north for 9 years. Not going to let it happen again.
4th and I think 5th gen. AC drain hose is on the passenger side but terminates short, about 2/3 way down the engine bay. In rust belt, that hose will drip water down onto the frame and rust it out quicker. Extend the hose down to below the frame when you can.
Thank you for your video. Questions: where can you get those stainless steel screws for the taillights that are compatible with the screws on the vehicle? Thank you
2015 4Runner in rust belt here. The entire trunk window assembly is rusted completely through. Surprised the rear window hasn't just collapsed into the door. Can't use trunk back window anymore. As mentioned that rear trunk area always stays wet and pulls in road debris when driving. Rear brake lines completely rusted and burst causing a complete failure of the braking system. Have to drop the fuel tank to change them due to how they're routed. Spare tire ridiculously rusted. Power steering line rusted out and leaking. Rear trunk lock, I'm on my 3rd one. They keep rusting out and failing. Great vehicle but there should be recalls from Toyota to have this vehicle spray coated. If you own one do yourself a big favour and spray coat it with rust protection every year, especially inside the trunk back door. Incredible Toyota has been making the same 5th gen truck for so long and have not addressed these issues. I guess they want you to just buy another one.
As far as the frame, they rust from the inside out. So undercoating does dick. You'd have to strategically spray fluid film or something inside the frame
@@ftwbeard1730 I will put that on my running list... I am making a list and posting it on my tool chest of all the little things I want to do after this winter. Thanks for the heads up on this stuff !
My 1996 4RUNNER same problem had to replace rear bumper rusted from inside out I thought Toyota galvanize their trucks my passenger side rear frame has a small crack sprayed lubricate under neither trying to slow rust lol.
I'm late to this vid, I see a Virginia plate so they are considered as a rust belt state, gets salted roads I believe. 10yr old car at time of this video so untreated will def show rust, not surprising after such a lengthy period. Those living in rust belt know that yearly undercoating preventative maintenance is way to go. Got nothing to do with design flaw.
@@michaeldbhawker3556 what about the oil type of undercoating? All of my mechanics say they hate working on them (greasy) but admit they help slow rust.
@@katiejon17 Crown undercoating seems to help . The main thing I do living in the rust belt is wash off the underside a lot ( at least once a week ) in the winter with a car wash wand . And with the motor running I also raise the hood and rinse off the inner fenders , radiator , brake lines and under the hood .
Depends where you live. I have a tundra, Tacoma, and 4Runner, between 5 and 12 yrs old. None have rust issues. We don’t salt our roads here and summers are usually bone dry.
Thank you for this video, I have the same runner, took the tire down and took a wire brush to it, then rust protection. Thank you Sir for this video.

Gonna rethink Toyota for next vehicle. My 15 year old sierra was awesome and I’m in rust belt! Ty!!!!
Wow, and I thought it was only a 3rd gen 4Runner issue. Toyota does everything well expect for their frames.
4th and I think 5th gen. AC drain hose is on the passenger side but terminates short, about 2/3 way down the engine bay. In rust belt, that hose will drip water down onto the frame and rust it out quicker. Extend the hose down to below the frame when you can.
Thanks...i appreciate it!!
Yup, my 2006 Corolla is the same way.
Good tip! That is condensate water I think which will be acidic and very corrosive.
Your correct. I discovered that this drip contributed to my floor rotting out on my passenger side right above the frame rail.
Tricky Japs you can’t trust em.
Thank you for your video. Questions: where can you get those stainless steel screws for the taillights that are compatible with the screws on the vehicle? Thank you
I got those at advanced auto..they have an entire section of stainless steel hardware.
@@ftwbeard1730 thank you for the info!
@@ftwbeard1730 is there a link to their website?
Thanks for this.
No problem.

Good attempt to protect from further rusting. Which year is the 4runner?
Its a 2011. I keep my vehicles forever. Hoping to get many more years out of it.
thanks for the info
Undercoated mine right when I got it!
Well, sounds like you did a good job on fixing it..👌
Hopefully..rust is the death of a vehicle.
Does the factory warranty cover “rust”?
As far as the frame, they rust from the inside out. So undercoating does dick. You'd have to strategically spray fluid film or something inside the frame
Wondering if all those screws were same size to buy a pack or were they different sizes ?
I took them out and roughly matched them up at an auto store. Stainless is expensive so they are usually sold in 2 or 4.

what year is this.truck

I think they've gotten better but still have a long ways to go. I keep an eye on the underside now and touch up the undercoating whenever needed.
My mothers 2007 never had probs, weird
Don't forget stainless for the screws underneath on the plates or you'll never get them off,
What did you use for undercoating
I hit any surface rust with a wire brush and then go over the bare metal with rustolium.

Hope you didn't use rubberized undercoating? That stuff causes the rust to accelerate.
Yup. Never undercoat rust. There are dedicated products for rust mitigation.

Wool wax and fluid film are your friends
Fluid film
Everything every year. Last forever
Every Toyota has terrible issue with rust. Toyota needs to use better steel, or stainless steel altogether.
That’s simply not true.
@@Starman-yt8lj Yes it is. Some progress, on my 2018, I noticed my front bumper beam is aluminum!

Toyota is selling out to china
Tell me one vehicle that will last longer than a 4Runner?
