RUST! Third gen taco

Most of this rust is on the welds, This is totally normal in the rust belt. Wire brush them and coat with a rust reform and primer. The other rust here is just surface rust I would probably use fluid film in those areas.Overall you did a good job keeping it in good shape continue doing what your doing
Don’t worry so much drive it and enjoy

 

What makes you think an older truck would be in better shape? The last 2nd Gen would be 3 years older than your current truck.

 

Yeah, and unless that 2nd gen tacoma comes from a hot dry state like arizona, its going to be worse than you have now, unless it was rust protected. Welds are usually the first place rust takes hold. Unless treated it will spread.

 

Don't recommend in a place wear they salt the roads, it peels and can trap moisture or salt. If your worried about rust stick to an oil base undercoat.

 

I just went out and took these pics. 2006 4Runner with 170,000 miles. Spent its first 10 years exclusively in Ohio, PA, NY, and NJ. Lots of snow and road-salt driving (Upstate NY is ridiculous). I never treated it with anything. Just washed it regularly. You can see the rust seems to be where the welds are.

 

What’s wrong with the stock ones?

I take my truck off-road and no issues whatsoever.

 

My brother bought a 2001 highlander from flordia, and had it driven up here where it spent the next 10 years on salty roads till the engine failed due to being a sludge one. That suv was had no rust protection, but had very little rust. Its weird how some toyota's like that can have a near perfect chassis after 10 years, and you have tacoma's built at the same time need new frames, all driven in the same conditions.

 

They barely cover anything....thus I used the word "inadequate". I can see the chassis and look from one side to another. What's the purpose of wheel well liners?

 

The ones on the 2022 are very flimsy. There aren't even any flexible flaps to cover the openings to the engine. It is exposed.

 

Didn’t mean better shape than my current one, second generation just more badass without that undriveable transmission

 

I'm not sure that he's wrong though! I saw underneath my 2012 last week after not having it on the lift for a few months and I was appalled by what I saw for new, dry-looking rust. I'm going to undercoat my new 2022 twice a year for a while. Spring and Winter. It's worth pointing out that he is in NY where they salt the roads and you are in BC where vehicles don't rust. You obviously don't know what you are talking about.

 

Disagree.

I had a 2022 T4R loaner for months with the 5 speed and 4.0 combo and didn't think it drove any better than my 2016. It certainly had worse gas mileage than my lifted truck on 285s.

Everything else about the 4runner I loved but was not a big fan of the engine. It actually felt like it had less power and the 5 speed made it feel like it was revving too much and needed the extra gear I'm used to at highway speeds.

 

Just stay away from those hard rubberized undercoatings.

 

let me clarify my comments:

* salty brine water is sprayed up into the frame and crevices of the undercarriage all winter, by driving on wet roads.
* getting in there and cleaning the salt water out in springtime, and then spraying an oil or coating right afterward, again in springtime, will stop that salt water from oxidizing the metal in the humid moist air of summer.

* OR conversely, washing out all the salt at the end of summer/ early fall, allowed it to stay in your frame for 6 months . . . went straight out of winter, covered in salt, and drove it like that for 6 months, and it had all that time to corrode.

which do you think is better for stopping rust?

Getting the oxidizing agents off your vehicle as soon as possible. Then covering the metal with a coating that acts as a barrier between the air and the metal will ensure the best results.

 

Good Advice.

salt water will inevitably find its way behind the rubber undercoating, and it will rust like mad and you’ll never even see it. (Until it’s too late.). Ziebart is awful.

Krown is decent. Or, often you can find a private shop that’ll do FluidFilm.

 

I tend to agree. Ideally what should happen is coat your vehicle after purchase. And dependent on your environment, rinse the bulk of salt off when it is convenient and also above freezing during winter, or if that’s just not going to happen, do a good exterior rinse and flush the frame in spring. And let it dry for a good while then top up your rust protectant.

Now do I hold myself to something like that? No, but I have rinsed at the end of winter pretty good and reupped my coat. The newer frames tho with all the plugs are more resistant to so much crap in the frame which helps.

Any brine/etc within the frame isn’t going to be rinsed out driving in rain or anything, it’s just going to sit. So no point in leaving it all summer til next winter. My personal opinion is most people have no earthly clue what is going on inside the frame. The exterior really doesn’t matter, as we have seen time and time again with perforation starting inside out.

 

Those are fine as long as you don't mine repeating the job every year if you live where i do. With a cosmoline type coating its one, and done, at least for a way longer time. If the military, and the germans use it on their vehicles its good enough for the tacoma.

 

I'd get the frame treated. I have pics in my album of my 2010 that failed and got reframed last year. Got it Woolwaxed last fall.

 

Ok, but why does the alternative have to be to wait until the end of summer to rinse down the frame? lol..

I would wash the salt out of the frame in spring like you suggested, but wait to get a good month of dry heat through it before filming it. Hell, wash it down AGAIN in the midst of summer before filming it, but at least that way it will be during a season where things properly dry out.

My initial point was, why seal a wet frame (unless spring is dry where you are)

 

You’re assuming people have no earthly clue, clearly based off your first hand experiences / relationships. Mine are polar opposite to that. Live in a town of 2200 residents (Tofino) and anyone that I know here that has a vehicle worth a damn does something about their frame / undercarriage.
If you bought a brand new truck here and did nothing, in 10 years your frame would snap like a fucking twig.
Just saying.
