BMW E46 M3 Subframe Reinforcement and Bushing Installation | vlog 085

[@VntaBlxck]

The production quality of this video exceeds all other subframe videos. Future people who need this diy will continue to thank you.

[@BlackFlagged]

Thanks so much 🙏

[@kennysimon633]

And one year later Matt I'm thanking him for this video

[@gregoryweekley8182]

Just so you know man thanks for the motivation I build my e 46 alone and to see someone else doing more then me alone goes along way good work man

[@markcayetano9179]

Of all the DIY e46 videos this is pure gold!! Thank you

[@BlackFlagged]

Awesome, thanks!

[@plausibleg.3170]

Guys, such as yourself, helped me through all my E46 repairs. Very thorough and to the point. Thanx, for your knowledge.

[@BlackFlagged]

Awesome, thanks for the comment. And you’re welcome! Happy to provide any help I can.

[@stymiesnerdly771]

Good on ya brother! I had my rear subframe reinforced at an indy shop because it was just too daunting to try and tackle myself. The one thing that I wish I had added at that time was upgrading to adjustable rear camber arms. It would have been so much easier & cheaper than having to go back in after the fact to get that done. I did replace the RTAB too, so next I'm on to bullet proofing the VANOS system. Glad you're back posting again!

[@BlackFlagged]

Thanks man! Yeah good point on the rear camber arms. I feel like I’m always limited by budget. But yes VANOS is next on my list as well!

[@dirkdiggler5647]

How much did it cost to have a shop do it if you don't mind me asking. I had a local shop quote me several thousand dollars. I can't imagine what the dealership would charge

[@Oneworld1116]

Well done. Much respect for you to tackle this job. Had mine done by my mechanic. Finally decided this past year to move on from the E46 M3 for road track purposes. A lot of people are coming back saying they still are getting cracks in subframe mount points even after doing this update. That you need to reinforce the top half by connecting the mount points and reduce twisting. Mason bar and some other solutions available. I decided to move on as it’s just too much of a hassle to sort this car out for track duty. They’re still awesome cars.

[@BlackFlagged]

Thank you. And interesting, I hadn’t heard that. Will definitely look into it. What did you move to?

[@Oneworld1116]

Well...I splurged and got a 987.2 Cayman S. I still miss my e46 M3.

[@BlackFlagged]

Rick Lynn ooh nice choice! I’ve always been a Porsche fan first. Just couldn’t afford it. Yet 🤗

[@victortran247]

You could also look into the Vince bar from Vince Philstrom in Sweden. Stealthy install and redistribute the subframe load to more reinforced areas of the chassis. Nice work. I'm going to do this in the off season, won't have enough time to do this despite having all the parts.

[@e36328isport]

You did well getting the whole subframe assembly removed in one hit. This is inspiration to get my black m3 done now. This’ll be the 3rd e46 rear end in bits for me. I love a challenge 😂. Really well done Dude👌🏻

[@BlackFlagged]

Thanks man!

[@victorpascua7917]

Dude, you're honestly the best content creator that the e46 m3 chassis has. Videos are entertaining and informative. Keep it up man, you're great

[@BlackFlagged]

Awesome man, I really appreciate that 🙏

[@jermainesmith1333]

I take my hat off to you, subframe is a lot of work on any car. E46 is definitely one of the time consuming car subframe to do. I got lucky when I bought my car, my good friend from Boostlogic in Austin Texas did my subframe and every single bushing in the rear of my M3. Then shipped my car to me

[@BlackFlagged]

You definitely got lucky then. So much work...

[@NigelsModellingBench]

Respect to you buddy!! Finally, someone who knows how to weld a crack.. so nice to see your good looking welds. Not so easy upside down, changing to vertical then upside down again. Oh.. just got to 10 mins and you said you had your friend do that welding.. never mind.. Quality video!!

[@11Xshadowolf]

You thought this was hard with a lift.... Did this laying on my back ... awesome video sir.

[@rabmc]

Great video and fantastic tips, I myself have a e46 m3 and have done for many years, on visual inspection no cracks but who knows what lies underneath, Reddish motorsport here in the uk specialise in the subframe reinforcements so one day will no doubt visit them, this is way beyond my skill level what you just done. Fantastic to watch. 🏴󠁧󠁢󠁳󠁣󠁴󠁿👏🏻❤️

[@BlackFlagged]

Thanks! I did a visual inspection on mine a while ago and couldn’t see anything either. So like you said, who knows what lies beneath. Thanks for watching!

[@shugs40]

Really like ur channel. Nice M3. I’ve just finished doing this to mine, made exactly the same mistakes/errors of judgement, that u did. Took me forever to get the rear end bolted back onto the car. WTF were we thinking trying to bolt the whole rear end back on. But we learn by our mistakes, I bet you won’t do it that way again and ur pain isn’t in vain if somebody watches this and does it the easy way. Shugs.

[@BlackFlagged]

Thanks. And yes no way will I do it that way again. Like you said, we learn from our mistakes. But that’s part of the process.

[@emanueladamache7034]

did this for my 330. had the car up on jack stands in my garage for a month... getting shivers just thinking about it...

[@BlackFlagged]

Lol. Post traumatic stress.

[@cl9170]

Thanks! Greetings from the US 👍

[@gerardwalsh4724]

Man, your rear axle carrier panel is in great shape! For a pretty high mileage car? Dayum.

[@BlackFlagged]

I thought the same thing. Clean!

[@gerardwalsh4724]

@@BlackFlagged I've got 80k miles on mine and it's in way worse shape. Visible cracks from the spot wolds around the sub-frame mounting points and a big one travelling up the fold in the floor panel. I think after the CSL in 2003 the changed some of the spot welds, or added more, because cars from 03 onward seem to be more solid.

[@samjohns513]

@@gerardwalsh4724 that's a myth, all years crack and all years have rod bearing issues

[@Gonzosport9]

I love how projects that are so complicated look so easy on video. Lol but great video bro can’t wait for the next one

Best sub frame video ever

[@ziggyfreud5357]

Mate that is a very very nice e46. Exactly like mine except mine had same silver wheels. Was totalled in a head-on. Very sad. Good job. Absolutely love the car

[@Col-23]

First vid I watched and I like! I’ve also got a e46 coupe and need to do the rear end, this vid just helped me! Thx man keep it up..... ✌️

[@BlackFlagged]

Great to hear, thanks!

[@ninobrown5524]

It'll rust under the welds, should've coated the car with weld through primer before adding the reinforcement parts.

[@adamrugen1850]

Nino Brown yea, if you used the car as a submarine I'd probably say you're right.

[@lokifurian]

@@adamrugen1850 moisture finds its way through everything eventually

[@BlackFlagged]

Good point. I don’t plan on driving it in the rain anyway. As much as I can help it at least.

[@logicsfinest3471]

Nino Brown out of curiosity, how do you add primer before you weld something? Wouldn’t the weld burn off any primer? Wouldn’t you put any rust protection after the welds? I’ve never welded a car before so I’m asking.

[@pch_mechanika]

@@logicsfinest3471 there are special types of primer for this - it will burn through it as it has to. But it will secure the metal around it. Google about these primers

[@notavailable9164]

[@matthewgorgoglione5492]

It's an easy job🤔🐘📐, and shouldn't be dirty using a lift🤗🤙☕🔨

[@gregskuza7166]

What was the reason of removing one layer of metal (the 3 drilled holes in trunk and cut the top layer out) just to weld it again? Was there anything added there?

[@laurentvigneault-pinard1634]

How easy it is when you have a lift and don't have to crawl under your car on porous asphalt without a creeper, with 1' 1/2 of clearance and remove the subframe of an e46 at 35°C, piece by piece... So yeah, I did what you did, but in far faaar worse conditions than you faced. It was tough, but not super hard Appreciate what you have, cause it can always be worse

[@BlackFlagged]

It’s not my lift, but belongs to a good friend. I still appreciate it though, because I don’t think I would have attempted this job without it.

[@jacksmith3189]

Good information Thanks

How did you strip the diff bolt. Did you upsize to m16 or helicoil?

awesome.......I would hire you as my mechanic

[@TheBlackdragon936]

Can do it as it’s my daily but I had my Indy shop do it. Now I am having high engine noise faults on the BMW computer so I am thinking it’s the rod bearings.

[@BlackFlagged]

Oh no, let me know if you find out what it is.

[@chrispewkreme]

Well... I guess I will wait til my subframe fails and just let insurance total it. Awesome video but I doubt I can knock that out.

[@BlackFlagged]

Lol good plan

[@icebear1935]

Wow what a big job, dread doing this. Will you do your bearings?

One day, yes. But not for a while.

This is the one i ended up using for everything except the diff mounts: 8MILELAKE 23 Piece FWD Front... www.amazon.com/dp/B016W4LHZ4?ref=ppx_pop_mob_ap_share The one I used for the diff mounts is just one I rented from the auto parts store before I bought the one above

[@BlackFlagged]

Thank you!

[@pistonpoweruk]

Hate to say this, but plating is not enough. The only certain way to do this, is to tie the subframe mounts into the chassis legs. The plates only move the stress to other places that will fail.

[@BlackFlagged]

I’ll look that up, thanks for the comment 👌

[@_aux7816]

[@DanAvon]

The differential install is incorrect and possibly what attributed to the front bolt stripping. The front bolt and two rear bolts should be threaded hand tight and then the front bolt is to be torqued first (correct torque spec is 148 ft/lb) followed by the two rear bolts (correct tightening sequence is 15 ft/lb followed by a 90* angle torque).

[@BlackFlagged]

Good to know, thanks. I can’t remember the exact order I really did it, this is just how I put the edit together. But thank you for the tip 👍

[@tonymontana897]

Dude, you have sparks flying everywhere inside the car during your welding and grinding !! Why didn't you cover the upholstery ? I bet there's burn holes everywhere now..

[@BlackFlagged]

I know I thought of that as soon as I was done. Thankfully I checked everything and there were no burn holes.

[@bryangrimshaw5607]

good video but there's a reason BMW put somewhat squishy bushes and not solid as a rock Acetyl in there and reinforcing the body is good, but only shifts the problem to the next weakest point on an already marginal body design. the English boys - Beamish do loads of videos on the topic. a little anal yes but thorough. your style is great and a very informative easy to follow format.
