Rust down below - serious?

Super excited to be in an FJ at last after eyeing them up on the streets as I drove by...but have looked underneath the car over the last few days (just bought last week from a Toyota dealer)...and saw this...is this rust something to worry about?

I have already ordered the PT938-00140 skid plate from amazon...maybe that will address it because this is a part of the car that will have to be removed for that?

A bit more of a concern is what looks like rust on the front left axle...should I be worried? Anything I can do?

Welcome and congrats on your FJ

Your wheel sale thread says you are in SoCal. Where did your FJ spent its life? Looks like northern/mid western, with that under carriage?

Re: Rust down below - serious?

The CarFax said 3 previous owners, all in California...so I'm a bit surprised...not very wet here.

Re: Rust down below - serious?

Thanks Iconic!

Really? I was tapping away at this at the dealership tutting and using it to bargain with the dealer

Isn't that rust there?

(I always remember that saying, rust = car death!)

Re: Rust down below - serious?

As long as its not on the frame I wouldn't be worried. That looks like really light rust.

Not the worst by far, but for comparison, here's a 2013 FJ that the son of a friend had me look at.
The top side was in really good shape.
The underneath showed that it had indeed spent time in upstate NY (carfax) before coming to Ohio - which isn't salt free either

Re: Rust down below - serious?

Wow, thanks for sharing those photos - really interesting to see the different wear and tear...

It seems, having checked out in person 5 FJ's to choose mine, that the lotions and potions available now to detail the car cabin, paintwork, wheels is so good it can distract you from what's gone on underneath. Your photos really show that.

Thanks!

BTW - what can be done about the orange parts (rusting?)? Is there a good way to slow it down?

"should I be worried? Anything I can do?"

"BTW - what can be done about the orange parts (rusting?)? Is there a good way to slow it down?"

stop asking and start reading Do a search here and read any of the dozens of threads on undercarriage rust / frame rust / is this too much rust / fluid film / rust treatment / undercoating

Many folks have posted tons of information over the years about what has worked best and all of the various levels of work vs. benefit.

Mostly it is cosmetic, but since most of us want our FJs to last for decades, not just, say, 10 years like normal vehicles, we're all kind of obsessed with rust prevention and treatment of the frame and chassis parts because what starts out as "merely cosmetic" grows to become terminal, eventually. The nice part is the body seems to hold up very, very well. The big concern is with all the black parts made of thick steel.

Re: Rust down below - serious?

looks to me like the previous owners drove it down a beach and got some salt spray on the front skid and the radiator support. If it were mine, I would make sure to fully spray off the underside and then spray on some WD40 or fluid film on the rusted areas...esp since you are in California and the rust is not likely to get worse. I would also make sure to spray out the frame rails (e.g. the inside of frame rails) assuming you are in a area where that will dry out fairly quickly

Frankly it looks no worse than cars here in Colorado that get some winter salt/sand and even with that being sprayed off regularly during winter, can have a light coating of rust.
