How To Repair Structural Rust Damage

Every situation is unique when it comes to rust and structural repairs like this. Consider this video a basic guide to structural body repairs, and nothing more. Note that some repairs are not practical or structurally possible. I recommend consulting with a body shop before performing a repair like this on your own to see if it’s worth the effort first.

That said, this video shows how I repaired the unibody structure where the rear subframe mounts on my 2003 Honda Pilot. Apparently this is a very common problem with these vehicles as well as Honda Ridglines and Acura MDXs of the same vintage. If you’re able to perform this repair yourself, or have someone do it for you, it can save your vehicle from the scrapyard.

Thanks for watching!

    I started watching your videos when I was 17 years old. I learned a lot from yours videos. Now almost 10 years later I work as technician and honestly I don't know if I would be where I am without your content. So thank you Eric.
  • @toddcott9510
    This is the sort of rust damage that puts the car in a scrap yard. A first class job, sir.
  • @roddydykes7053
    If anyone wonders why rust repairs are expensive, this is a good video to show Inspiring work as always
  • @laszlototh5956
    It is amazing how Eric's fabrication skills developed during the years. This was a pleasure to watch!
  • @martij30
    Hey Eric I just want to take a moment to thank you. I've been watching you for a couple of years now and I have learned so much. I'm a university student and I work on cars (both my own and those from family members/friends) as a hobby in my spare time. However when I visited a highly praised shop in my area to get some springs compressed (as I don't have the tools for that) they were so impressed by my work on cars that they offered me a part-time job as a mechanic! This was such a compliment for a hobbyist like me and I owe you a big "thank you" for learning me so much throughout the years. Keep on wrenching and I'll keep watching!
  • The cutting around the aerosol with a plasma cutter fail wad hilarious. Please include outtakes in all videos. Their hilarious. Nice repair as always eric
  • @panzerveps
    You might not be a fabricator, but that's a job well done. A job like that requires the ability to plan ahead and visualize the next couple of steps.
  • @WayneWerner
    "that's so cool, I built that" - that's exactly what I love about fabricating and fixing stuff like this
  • @MrAceyJay
    "Grinder and paint makes me the welder I ain't" Nice job. Sure there were other ways it could have been done but nothing wrong with the way you did it.
  • @FORDSKIN
    Hi Eric, weld through primer is a great product to help reduce corrosion on the surfaces you cant get to after welding.
  • @bushratbeachbum
    Love your work mate. Nice one. You're encouraging people to do things themselves, in a world where they either can't be arsed, or are too scared to break the norm of paying money to fix a problem. We need more people like yourself. Cheers!!
  • @iblistarhun
    This was very impressive, Eric. Well done. I'm a layperson (my work is in IT infrastructure so my tools are all virtual and not physical) and I enjoy watching your obvious skill and experience in a domain so clearly different from my own. Very cool.
  • @trevkeay5555
    Thanks Eric, like a load of guys here, been watching for years & your videos have inspired confidence in me!...Plumber by trade, taught myself to weld few years ago. Now welding my 20 year old ford escort 1.8 diesel van regularly to keep it on the road & earning me money. The way they were built (well actually chucked together) & not rust treated, they were like consumables!! But thanks again for ALL your excellent videos..learnt so much over the years, (Bridgwater, Somerset, ENGLAND)
  • @cityside75
    Your comments about the worthiness of this repair on an old vehicle is exactly the calculation I did before I started doing some body and frame restoration on my Subaru. While I agree with your overall assessment and this kind of work makes a lot more sense when you can do it yourself, you took non-road worthy car that wasn't worth much more than its scrap value and turned it back into a vehicle that can be operated safely and sold with a clean conscience. So you have added thousands back to the value of the car. This was my way of justifying the amount of time and money I've invested learning these skills.
  • I just watch Eric because he just connects so well. His attitude seems genuine. Simple truth.
  • @pauliek5179
    Glad to see that you're still doing videos Eric! Used to watch your stuff when I was a younger man, you're the reason I got into working on cars, absolutely an inspiration keep it up!
  • @Boilaroomnick
    I just bought an 07 Sierra that I have to repair one of the crossmembers and a small part of the frame on. These videos give inspiration and confidence to tackle something most people would shy away from, so thanks!
  • @johndimech8945
    An absolute work of art. Soooo satisfying to figure out and carry out your own solution. Job well done.
  • @JrSpitty
    I got into the automotive field because of videos like this! Just started a job working for a RAM dealer. Can't say if it wasn't for an instructor and watching videos like this I would have chosen this path. The creativity and passion to perform jobs that you wouldn't normally consider yourself good at shows you are willing to learn anything and everything like a true professional, that is the same mentality that has inspired me! Thanks a lot for this video, it is well outside of your normal stuff and very inspiring! :)
  • @Gmacc187
    Hey Eric I bought a Chevy Malibu from my brothers mechanic "friend". A few years ago I would've been screwed. Now if days I see it as more of a challenge now. Your videos have been crucial for me taking my vehicle maintenance into my own hands. This year I'm going to a trade school to be an automotive technician. You'll never understand the positive impact you've had on my life. And without a doubt I wish to pay that positivity forward by being honest and thorough like you are. Thanks for all you do Eric.
