How To Repair Structural Rust Damage
Вставка
- Опубліковано 23 вер 2021
- 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.

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.
I’m 17 too & I just started watching yesterday lol, hope to become a technician too
I also found Eric about 10 years ago, while working as an apprentice. He's one of the reasons I passed my final exam.
I'm truly honored by your comment. When I started ETCG I had hoped my videos would help people. I never expected them to inspire others like you. Thank you very much for that comment and good luck with your career.
Hello Eric, I started to watch your videos in either 2010 or 2011, it's now 2022, and your videos have been extremely helpful.
I worked in auto service garages before, and currently I work on my own cars, as well as for family and friends.
With Much Thanks to you and your videos.
@@theroyalcrownedtiger2946 you’ve traveled ahead in time, how are things in 2022? Did we concur COVID?
This is the sort of rust damage that puts the car in a scrap yard. A first class job, sir.
If anyone wonders why rust repairs are expensive, this is a good video to show
Inspiring work as always
Bondo and pop rivet rust repairs are less expensive. This video shows how it is done properly resulting in a safe vehicle.
He did that repair in 25 minutes though, that shouldn’t cost $3k+! /s
@@BlazingLightSword the repair was condensed to a 20 minute video. I'm sure he has more time in it than that!
As he stated, he's not a welder or fabricator. Plus he took the time to video it. Setting up for video takes time.
For a beginner, like me, he did an excellent job!
*A cast sleeve in a welded mount under a stamped raised ROUND footing. I don't know a lot of guys that would've fabbed that from scratch, especially with only three tools. Good stuff.*
@@BlazingLightSword you actually thought that took 25 minutes? SERIOUSLY?
It is amazing how Eric's fabrication skills developed during the years. This was a pleasure to watch!
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!
I never get tired of hearing how my work helps people. Thank you for taking the time to share that with me. It's totally awesome that you got that job offer. Well done! Thanks again and have a great weekend.
@@ericthecarguy Thanks a lot for your reply, have a good weekend as well!
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.
I am not entirely sure why he put the flat disk on when he did and not last.
@@Oblithian probably to make sure the rear subframe was positioned correctly when checking the fitment.
Sucks I can't visualize
"that's so cool, I built that" - that's exactly what I love about fabricating and fixing stuff like this
"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.
Hi Eric, weld through primer is a great product to help reduce corrosion on the surfaces you cant get to after welding.
i wonder how do they do on assembly line, the metal panels are raw they weld them and then paint it ?
@@mondecruel1866 at the factory, the body in white is fully submerged in a vat of primer that gets into every single seam and blind cavity (if you have ever looked inside a trunk without the trim and wondered why are there so many stamped holes that needed to be plugged up, it’s because those were drain holes to let the excess primer drain out of the body as it was removed from the vat)
@@mondecruel1866 They dip them in an acid bath after. Then they take other baths in sealer/primer.
@evolence detroit Look at any video that covers a modern assembly line.
Ecoat is only done on replacement body panels so that they don’t corrode while sitting in inventory.
All new cars during production do not get an electrolytic coating because it creates unnecessary prep-work steps through the production line.
The chassis and body panels are finished raw.
On a full production line, the chassis are dipped in an acid bath to etch the entire chassis, rinsed, then dipped in sealer/primer bath. Then it gets its finish coat from robots.
@evolence detroit No matter how it's done, NOT even attempting to paint or rust coat bare metal is wrong. midwest to east coast, rust through in 5 years on this very decent repair. What a shame.
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!!
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.
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
I do post out takes when I have them. I normally put them at the end like I did with that one. Thanks for the comment.
@@ericthecarguy ah I don't always see the very end then. I will have to make sure I do that. I've been watching your videos almost weekly since your old garage. You taught me how to do an oil change. Must've been near 10 years ago now.. anyways still enjoying the content.
They're** hilarious, you're right.
@@SalandFindles you must be fun at parties 🥳🎉
Not one of Eric's smartest moments. Still glad you included it in the outtakes.
👍🏾 Good job man.
You've done a better job than every body shop "tech" I've ever seen. Awesome video!
Great repair Eric! I was thinking you might need a thicker plate around the bolt, but you boxed it in nicely. As an amateur fabricator myself, it looks good enough to me. I was especially impressed with your trick of bolting everything together to get a proper fitment. That was smart thinking. Some tips I learned from Mustie1's videos, is to now spray oil up into the newly fabbed piece, now that it's done. This helps prevent future rust. He uses bar and chain oil. I have used fluidfilm for this myself, inside doors I fixed.
I use pop and beer boxes for making my templates. They're always around and they come in different thicknesses. 👍
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!
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!
I use cereal boxes for making my templates in metal fabrication. stiff enough to hold it's shape, but can still be cut with scissors. Besides, everyone has cereal boxes, and you don't need to go to Staples for manilla folders!...lol. Great video Eric!
Old oil and air filter boxes work good too
CAD. Cardboard Aided Design.
milk cartons, for those that get it in cartons anyway. lol
I use a cereal box when spraying my motorbike chain. Cut a side off so you get an L shape at the fold, then protect the tyre with it.
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)
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.
No I haven't. This Pilot is worth $4000 on its best day. It's not it's best day. This repair would have cost somewhere in the neighborhood of $3500 if you took it to a shop. I still need to replace the transmission which is another $3000 in parts alone. Not to mention the front suspension repair, the interior, and the engine service. In all, I'll probably have at least $9000 into this $4000 POS. I don't think that's good money spent at all, but it makes great content, and I'm happy with that. Thanks for the comment.
I just did a 97 CRV, where the trail arm bushings mount up. It was my first go at fixing structural rot, and I'm very happy with the results. I ended going with what your original plan was, welding a nut behind the first layer. I did not consider it needing movement, however after watching this I am still pleased to know someone with much more experience then I had a similar idea. Very confidence inspiring. Thank you!
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.
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! :)
Great work. I just started restoring the frame of a rusted 1950 plymouth and having never welded or fabricated before I find that my solutions are improving all the time. Yours looked great! Thanks for the vid.
I just got done replacing bushings in my rear sub-frame. Oh, man, every time I watch one of your videos where your under a car I count myself lucky to be a California kid who doesn't have that level of rust to deal with :) But I really enjoy seeing you defeat that rust!!! WAY TO GO!
Yes, our vehicles rust out before they're worn out in the rust belt!
I couldn't believe some of the cars in California - 30yrs+ old car and no spot of rust. I envy my sis.
@@pliedtka I work as a lube tech for a local place here in the Bay Area, 30+ year old cars VERY RARELY have rust on them here.
An absolute work of art. Soooo satisfying to figure out and carry out your own solution.
Job well done.
I just watch Eric because he just connects so well. His attitude seems genuine. Simple truth.
Eric, love both your comedic and master mechanic talents- awesome video, learned so many new tricks that I plan to apply on some of my upcoming projects! Keep up the great work!
"Oooops!! ....sssssshhh... Well, I don't recommend that!" 😂🤣😂🤣😂🤣 Brilliant content Eric, regards from Galway, Ireland 😉👍💚
That's an impressive job of fabricating Eric. Thanks you for letting us watch.
I really like that repair Eric! Also that inside the frame coating will make it last. It should be even stronger than when new! Great job 👏
I think you did a superb job Eric and having a two post lift certainly doesn't hurt! 👍🏻👍🏻👍🏻
Few things are as satisfying as doing your fabrication-type repairs. Being relatively new to welding myself, I've done some of this and boy does it feel good to look at what you've done and know that it's a good repair.
Wow, nice custom work! Loved seeing your process, and hearing you explain your rationale. Good stuff!
Thanks for share all this information Eric, i respect you a lot and admire how much love and effort you put on your work, greetings from Guadalajara, Mexico!
You've actually helped me out of bad funk ive been in showing it's okay to make mistakes and that it's all fun and learning thankyou tons!!!!!
Superb video Eric! I'm going to be doing a similar unibody repair on my 2010 Ford Escape. This gave me some great insight on the plan. By the way, I've been watching since you started years ago and your technique and quality is as great as always! Thank you!
man, how much patience you have.. kudos..
my chrysler town and country is 1997
greetings from Croatia !!
This turned out really well!! Great job Eric!!!
I'm glad you shared this before I scrapped my Jeep, might be able to squeeze another year out of it now.
Your videos have been my favorite for over 10 years
I'm impressed, beyond words! Thanks for this astonishing post, I'll be watching more!!!
Really cool video.
I’m working on a 2007 WRX to repair with my 14yo son. Learning to weld, what materials, techniques. Super appreciative, great job!
That is a nice, well thought out and implemented solution to a very cancerous bit of structural frame rot. Well done!
Thank you!
OMG. I'm a little ashamed that I haven't watched your videos in 2-3 years (other than your video about being kicked out of your present shop moving to a new shop) What a great masterclass in fabrication. Thank you. Kind Regards, Craig
I've said it before and I'll say it again, you are a valuable asset to the honda community! Thank you, stay dirty buddy!
I've mention this guy's UA-cam channel to others who are doing body repair. Fitzee's Fabrications has outstanding instructional videos when it comes to body and frame rebuilds. Cheers!
Cavity wax in the end to fill those gaps. Awesome job. I need to break out my new welder and do some repairs. Thanks for the video.
Love your videos, Eric. I started watching you when I first started out as an apprentice in 2014. Sent you an email around that time. Never even considered you would respond, but you did. I've learned alot from you. Thanks for everything you do.
Thank you for your continued viewership. I hope you're enjoying your career. Thanks again and good luck.
Nice work Eric, always satisfying doing this type of repair. Cheers from the UK.
I don't subscribe to many UA-camrs. But it's people like you that makes knowledge power
Nice work!! Thanks from the UK for the video Eric.
That was Awesome Eric!!! Great job and what a money saver! Thanks for the great videos. As always.
The thought a nd thinking and doing process in making the rusted out replacement part was like open heart surgery for body work. Very well done. Great problem solving skill!
Great job Eric! I have to do this on my 06 Sienna, so the timing was perfect!👍
Great job Eric. It was insightful to watch your process after I myself recently refurbished holes in the frame of my 1988 Subaru Leone. Probably fewer of them still on the road than Honda Pilots and the rest of this vehicle is virtually immaculate so I was motivated to repair this class is rather than junk it.
That's exactly why this is such a valuable crash course tutorial: the econocars of my youth are now quite rarely found as most of them were driven to "the farm"; healthy powertrains carrying rusted out shells
Excellent craftsmanship ,a lot of thought ,executed in a professional way ...😀😀😀.
Wonderful Work Eric & very nicely done. It was worth watching.
Eric the car guy and Eric O.....two of the best mechanics!
Looks great. I particularly like the tapping down of the curved outer covering. Good sound too. I sometimes drill holes before/after to facilitate the application of paint and rust protectant posteriori.
Watching your videos all these years have slowly made me distrust technicians, seeing you go way out of your way to fix the super small details that would turn into big problems down the road. There’s no way for me to make sure my mechanic is catching those type of things for me while he’s working. I highly admire your work ethic and I wish there were more like you.
Thank you. I actually made a video on that topic last week. ua-cam.com/video/bRmjIpvCgwk/v-deo.html
Looks like a solid repair. I liked your approach to fixing (I'm not a welder).
I hear that. Me neither. I bought a HF welder and have beenmplaying with it. Its pretty cool
I love the video and the how to nature of the repair process. I am repairing my truck but this process will work for me. Thanks!
Amazing techniques, and workmanship Eric! You dah man!
Its always satisfying when you make something like that, I love fixing rust
I just discovered a very similar situation on my 2004 Element. I immediately remembered this video and came to rewatch it. Replacing the vehicle isn’t an option right now and we love this Element so I want to fix it. Thank you Eric!
I just found it on my 08 Honda Pilot. FFs! No wonder she drives all friggin squirely. Mine is worse then this one with the mount point having completely pulled through. That said, I do have a cheap TIG / stick/ Plasma cutter, a grinder and paint lol. I've gotta pull it apart back there anyway to do some service on the rear end and figure out my VSA issue. This is our Daily, so something tells me i'll be doing this sooner rather then later.
That was awesome. Great video, Eric 😀
Very nicely done, Eric.
Thank you Eric I love watching your wonderful videos great job I am from South Africa
Real smart work Eric, i'm really impressed, thanks a million for sharing
Nicely done 👍. I learned something new today, thank you.
What an advanced understanding of metal and of the complex machines that cars are
This video was really calming and fastening and educational I like the idea of fixing these useful yet disposable unibody cars
Nice work Eric. Your welds are starting to look really good.
Awesome I like that 👍🏻
Your welding skills have improved nicely 🙂
17:00 "that's so cool, I built that" freaking awesome Eric This was fun to watch, your camera work and editing is on point as usual. Hope all is well my old friend.
Excellent presentation Eric. Also, your strategy as to how you approached this difficult repair is right on par with a similar repair I am presently working on. In my case, the unibody rusted out at the two front points where the undercarriage bolts into it. I did practically the same as you did with cutting out the damage, making a template, fabricating new pieces, using the undercarriage as a jig. My two fabricated parts are ready to be welded into the body. Since I never welded on a car body before, I am a bit anxious and and practicing with 16 gauge mild steel scrap first so I don't end up blowing holes through the body. I think I am ready to go at it now so hopefully, I can get my 2006 Saturn Vue back on the road.
Thanks Eric I found out that mine has the same issue yesterday and come search for your video.
Some of your best work right here.
Great fix Eric.. done learnt alot in this repair
I would have done this a little differently, but you did a great job regardless. Nice work!
Yep, I thought the same thing.
Nice work Doctor Eric !!!
Man oh man I'm very impressed with your work fab skills quality impressive that's not something people can do and you make it look easy
That's a repair to be proud of my friend. 👍
Awesome job brother looks like a professional repair IMO
Thank God we have Ericthecarguy bc I'm exactly what I'm fixing on my ek hatch atm. Again, thank you Eric!
Good luck!
Damn Erik. Honestly props man. It takes balls to start cutting out pieces of the frame (sub frame).
Really good video, well organized concise.
This video inspires and motivates me to spray more AD3000 rust proofer on my '05 Pilot
Great video as usual. I always learn a lot watching your videos!! Definitely helped with my own videos.
I miss my fab days now! Awesome work guy
I enjoyed the bonus footage!
Great info. Thanks Eric!
Fascinating to watch! And thanks so much for clearly explaining and showing every step of the way. Awesome. I learned a lot.
This reminds me of exactly what I had to do to my '89 Buick,
when I replaced the transmission.
One jerk in the Club I belonged to at the time- remarked it would be labeled
scrap where he came from, and he was very nasty and rude, something
about "polishing a _ _ _ _". He's a big deal Moderator now, 10 years later-
go figure?
Eric, you did a wonderful job here. Always remember- because the temper
is changed, a weld is always the first to rust. Keep welds to a minimum,
and treat them accordingly.
You could've made a "box" and made folds on a pattern, 2 welds. Easier
with a bender.
The threads are deep, so the shank goes up into the mount, more integrity,
less wiggle as possible. That's what the busing is for, giving movement.
A wiggling bolt would snap. The 4 bolts I had to buy were $30 each.
Bushings were $50 each, got all 4 for rear of front cradle.
I mean it’s an 89 Buick. He’s not wrong lol
nicely done eric
Great video Brother! Thank you for sharing. This will definitely be helpful for the repair of my 08 Pilot. 👍👍😎🤟🤟
man great job with that repair. I did learn by it even though I did a shit load of welding/repairing. I like videos of things I can also do myself, not some expert that has done this 40 hours a week for the last 30 years with some diamond-level looking repair thank you.
i just finished watching rust bros on netflix ... great show. nice job on the repair !
Nice repair Eric. Enjoyed watching this lesson
Great job Eric!
