Rust and Concerns on newly bought 2019 4runner TRD offroad

i bought a 2019 trd off road came with some rusted parts
want to see if some one can help me to see if its too bad or normal
and found this part label on the shaft . does this mean its been replaced ?

 

Label is normal, how's the rest of the frame look?

 

rest of the frame seems fine with some minor surface rust

 

The assembly line workers usually remove tags when they install a part, but not always. Just usually. Make of it what you will.

Picture straight down, that rust looks pretty bad. That's a pretty thin piece of metal. You might want to take a wire brush to it of some kind, and remove the rust that's there. If it's all the way through, you might very well want to replace that part.

I'm not sure what the picture beside it is, but that rubber is definitely blown out. It NEEDS replacement. If that's covering one end of the a CV joint, as it looks, it may well be rusted beyond saving. MAYBE. It needs a good exam.
The water hose beside it appears to be starting to get soft. I would have all the big water hoses like it checked at the very least, or replaced as a preventative measure. I do mine every year. Probably more often than necessary, by far, but I've never had one fail.

The bottom picture...
That looks like the connection to a cat, or the muffler. The worst of the rust is on some pretty thick pieces of metal, and is probably survivable. The fringes on the pipes look rusted through. You might want to have the pipes those flanges are on replaced. You definitely want to get the rust off the thick pieces, treat them with a rust inhibitor of some kind that can take the heat, and replace the bolts and nuts. Absolutely use anti-seize on the new nuts and bolts, but beware: it makes the torque reading a torque wrench off by a bit. I'm not sure the exact amount, but I'll see if I can find a chart somewhere on the net.

ALL this is just my opinion, of course. And if you live someplace, like southern Arizona, rust isn't really a big problem. Dust intrusion into everything, yes, but not rust.
If you live in the North East of the US, they use a LOT of salt on their roads, and it will destroy the underside (read the fame) pretty fast. Use something like Fluid Film to protect the underside, wherever you live. It works. It needs replacing every year, but it's a LOT cheaper than the frame of your truck!

Does that help at all?

The advice you are looking for might vary depending on where you live. It might make all the difference as to what people will suggest you do.

It would be so helpful if new members would put their location in their profile. Especially when help is needed regarding rust issues...

 

Not unusual to have stickers, mine still has some dating to 7/98. Its very common to get rust on exhaust components, if it bothers you then you can brush it with a wire wheel, but it will rust in a short time if you don't treat it with something (which can be difficult on hot exhaust components).

 

Thank you very much for the response Pat
sorry glwood54,i live in Topeka,KS. added location to my profile.

 

Trekker, thanks for the response . i just bought it from a local dealer(19th). Its a Toyota Certified supposed to be in pristine condition. i am taking it back tomorrow to see what can be done.

 

Those labels are tenacious little guys. There's photos of older Tacomas with the frames rusted in half but with the label still affixed in other parts of the frame. The joke is that those labels are what actually hold Tacoma frames together...

 

When you guys are spraying with fluid film are you just covering everything indiscriminately? That is how I have always done it on my wranglers but I didn't know if there was anything outside of the exhaust that you avoid spraying like transfer case and so on.

 

I sprayed woolwax liberally, but not indiscriminately. I sprayed a little more lightly on the T case but it still for some.

I made an effort to avoid the exhaust, brakes, and cv boots. The cv boots just to keep grime off so it didnt chew into the rubber as they flexed.

 

I sprayed WoolWax pretty much everywhere underneath the vehicle. Laid it on heavy inside/outside frame. Everything else got a light spray. Tried to not get any on the rotors or boots like McSpazatron said, but with the mist there is bound to be some that gets on them.
