Handling Rust in the Rear - 3rd Gen 4Runner Part 7

Today we handle rust problems with the rear frame and rear differential/axle because it is getting out of hand on my 2002 (3rd generation) Toyota 4runner. I plan on coming back in the future for a more permanent fix, but right now, the wire brushing/knocking the loose stuff off, Rust Kutter, Rust Reformer, and Cosmoline RP-342 will do a good job for protection for at least a few years.
Thank you for watching, I hope you enjoy and learn something new!

my rear end looks just like yours (did), and now I know the products and course of action I can take to get it looking right. Thank you!

[@mattuccibuilt3970]

That's awesome! I'm happy to be of help!

[@vb1gbg]

Keep it up! When you get the space and time for doing the final rust removal, I recommend taking the body off the frame. I've done it twice now without a lift outside. It also makes it easier to service the engine and suspension. Scary at first, but it's easier than people think. You should have a backup vehicle because you will want to spend more time getting to every component.

[@mattuccibuilt3970]

Yeah that's a great idea! I've got the commuter if needed, thanks for the tips!

[@palangnar3588]

I just find out about your channel, and own a 3rd Generation 4Runner and going to subscribe to it.

[@mattuccibuilt3970]

Awesome! Thank you, I'm glad I can be of help

This is not rust. Its your Grand father,s soul attached to it .

[@mattuccibuilt3970]

I'm not so sure about that lol

[@mikeypotts4732]

Wow I'm glad I live in FL lol. Amazing job!

[@mattuccibuilt3970]

I've considered buying a 4runner down there with no rust, thanks!

[@cordel666giglesworth6]

Oh I know the feeling I grinder every spot of rust and epoxy primed then polyurethane paint black

[@mattuccibuilt3970]

It's quite satisfying 👍🏼

[@ExtremeRecluse]

i would love to see what a good home made sand blaster would do on this under belly.

[@mattuccibuilt3970]

Only tough thing with that is you'd likely want to strip most lines that have fluids and some other components, so it may be worth just disassembling the axle and pulling it out to then sand blast it, but I do like the idea of a homemade one!

[@ExtremeRecluse]

Portable led high output shop light.

[@mattuccibuilt3970]

Great idea, especially when working under the vehicle, can be dark, would help with filming too!

[@666myname666]

There is rust in your moustache . File it lol

[@mattuccibuilt3970]

Yeah, there's rust dust everywhere haha.

[@reanthegreat]

Awesome work! How long did this take you in total hours?

[@mattuccibuilt3970]

For all of the work including taking all of the stuff off was around 8 hours, throughout a few days helped break it up well

[@reanthegreat]

@@mattuccibuilt3970 Oh wow thats surprisingly fast. Thank you for the reply! Love your content and it's super helpful! Keep up the good work :)

[@coffeewithj24]

Just got mine and discovered a bunch of rust underneath 😩

[@mattuccibuilt3970]

Yeah the box shape of the frame holds the water in

[@brandontignor]

I had someone sandblast the underneath and then painted over all the frame with black paint, I plan on doing this every 2 years or so.

[@brandontignor]

I would attach pictures if I could

[@mattuccibuilt3970]

If you don't mind me asking, how much does that cost? I was going to attempt DIY sandblasting but didn't have the means for it. It seems like the best way to get rid of rust by far.

[@brandontignor]

@@mattuccibuilt3970 well, I looked LONG and HARD. So I got it done for $450 all in from a guy locally. haha but the going rate I was coming into was about $1000-1500 on average.

[@mattuccibuilt3970]

@@brandontignor Yeah, thats close to what I was thinking, its crazy.

[@brandontignor]

@@mattuccibuilt3970 it's honestly still worth the work an labor for someone to do a good job for 1k-1500. I know it's alot. But worth saving up and getting it done. I can't tell you the weight off my shoulders it was to have it done. Like gawd

[@schlomoshekelstein908]

lol my 2nd gen 4runner doesn't even look that bad. did you fjord some ocean rivers or something

[@mattuccibuilt3970]

Believe it or not. this is in great shape for a 3rd gen that has lived its life in Utah. The salty roads absolutely wreck the underside of these.

[@Ali-iz4qd]

Where’s the next video thooooooo

[@mattuccibuilt3970]

Haha, Im working on it as I type this! I've been a lot busier lately, unfortunately.

[@Ali-iz4qd]

@@mattuccibuilt3970 can’t wait, hopefully you’re able to drop one every week, your content is nice. If you need any motivation i gotchu

[@mattuccibuilt3970]

@@Ali-iz4qd I really appreciate that! One of goals will be to do one once a week and since I plan on filming trips It should be close to possible!

[@thrRnz9496]

Bad job. You left a lot of scaling rust. That is all still rust. You failed to remove all of it. Covering it up with chemicals, wax and paint won't stop it, it will still rust underneath all of it, You said it yourself. You should have done it right the first time, if not, just use fluid film/surface shield so you can power wash it off later to properly treat it.

[@mattuccibuilt3970]

As far as price and longevity goes, I think I still made the right choice!
