My Son recently bought a 2000BMW 328i and it had the exact same problem as yours. The Drivers side sub-frame mount tore right out. After doing a little research and finding your step by step videos for removal, repairs and re-assembly it made this pretty big job do-able. Excellent videos! Thank you very much my friend for these videos, your paper work/torque specs, step by step procedures that you've supplied. It is and was very much appreciated. His car is now fully repaired.

This is such a great response! I am so glad that you were able to fix your issues as well. The entire reason that I made this series ( and all of my videos) are to illustrate what it takes to fix or do something so that others can determine if it is something they can take on (UCanDoIt2). These are fantastic cars and easy to work on. At 16 years old, you have to expect things to need repair. Congratulations on fixing this yourself! Hope your son enjoys this car, they are a lot of fun! In the last hours of 2016, you just made my year and the effort to share this series just made it all worth it. THANK YOU!

Getting ready to this repair at my home. Been watching/reading a lot about this DIY repair for the past 3 weeks. This is by far the most detailed DIY. Thank you for taking the time to put this together. It has helped me a lot.

Glad you found the series useful. It is a time consuming repair but relatively straight forward. Cheers!

The inner and outer bolts of the upper and lower control arms are supposed to be torqued at ride height, otherwise you'll get suspension binding and pre-mature wear on those bushings. It can be a challenge to torque the inners at right height with the diff reinstalled. Otherwise, this job is a labor of love in my opinion because of the time it takes and the reality of what a shop would need to charge. I was lucky and didn't have any subframe cracking, but was prepared to hire a mobile welder to come to house and pay them to do it...of course after removing the fuel tank and fully preparing the areas to bare metal to save from paying someone else to do it. You do this on a 15-20+ year old BMW because you love the car, can't justify paying several thousands to a shop to do it and/or you like a challenge. All of the above for me and your video series convinced me I could do it too. Thank you!

Watched whole series. Great job guys.

i took my time watching your videos, i have a e36 1995 and im having the same issue, i have very good knowledge in cars, this will be a task for me, my car makes that same noise when i shift from first to second and it got louder, i will jack it up and see, i hope that i dont have a crack since i dont have a welding machine, you really detailed your work!!!! thanks so much, now i know what im dealing with..

My thud isn't as bad as yours was so I'm hoping I won't have such large repairs to do on mine in the near future, am thinking of going poly bushes for ease of installation seeing as I don't have a bush press and the poly should last slot longer. Loved watching these videos though, so much information and it's put my mind at ease about doing it at home on the drive with basic tools ✌️

I just recently did mine a week ago. a 2000 323i manual RWD. previous owner sold me the car without telling me what that clunk and squeak noise was. I drove the car like that for about 9 months or so and this series really gave me the motivation on completing this scary task that I said "I'll eventually do it" I got to say I did cheat a lot though lol. I just moved the subframe a little bit to make clearance for grinding and welding my carrier panel back on and added metal for reinforcement. I did this outside in the span of 7 hours start from finish. One day when I have a garage and stuff I'll do it properly with reinforcement plates. But even the way I have it know will last and be really strong for years to come. Thank You so much with this series. I still watch it time to time because it is entertaining to see it happen.❤️

I followed all the steps you mentioned in the PDF. It took me totally 11 hours to complete the job. Great videos and clear explanation. I planned a wheel alignment, because I think putting the alignment on the same place will not work anymore because of all components were taken apart. The most challenge part for me was to insert the two differential bushings as there is no place to hold the iron ring (inner side of the frame). I broke two threaded rods during this process (but I was prepared, so had 4 in total :) ). Thanks for sharing.

Good walk through of the job! As mentioned in other video-comment I did this job myself on my E46, and it is a rather big undertaking.. Great work!!

I did guido, center bearing, motor and transmission-mounts and everything in the gear stick mechanism as well and also front bushings and full race spec coilovers.. It handles like a champ and feels like a new car. It must be wonderful to have a son who shares your interest in cars and to work together.. Thumbs up to you both!!!

Great video man! I've been hearing some clunk coming front he back of my e46 328i and I am almost sure its the diff mountings that have failed, cause as I can hear the noise quite loud under hard acceleration in 1st and 2nd gear. At least now I know it can be DIY-ed with some patience. Btw, I would he zapped the bushings out and back in with the impact, especially the rubber ones, as there is nothing that can really go wrong wit that. Still, quality material presented on your behalf! Thanks!

All say... is that those bushings are very hard to get off! :) Maybe an impact on the outer rim might work. It would not work if applying it against the inner metal part as the rubber would absorb all the impact. Thank you for the feedback. I strongly feel that all of this "Issue" is based on those three spot welds breaking loose (start there). After that it is all about how soon you catch it as to how much additional damage is done.

Tickled that I am reaching Pakistan as well!!!!! Have you installed the Reinforcement Kit yet? After completing this 4 part video series, I later thought of another possible Thump. In Part 3 @ 14:38, I show 3 factory spot welds that failed. I believe those 3 welds broke first which started the original thumping sound and that slowly got worst and eventually caused the complete tear out of the chassis metal. Yours may just be at the point where the 3 spot weld have failed causing the noise. It would be very apparent when you cut the window (Part 3) and correcting those welds is paramount. Many thanks for watching!!! I love these cars. They are fun to work on and being 16 years old I don't mind the few issues that we are having.

Thank you for the feedback! Ok so I don't think I spotted any failed spot welds. What happened was, I ordered a reinforcement plate from eBay (about $70), not the Turner one, and installed it when I was doing the 4 power flex subframe mounts. I also changed the 3 differential bushings that may have also been the culprit. My mechanic did all the work, but I inspected when the subframe was off, and there was a small notorious crack in the chassis where it folds (lots of people online suggest that's where the cracking starts). That was the only crack I say. Didn't see any damaged welds. Hence, just treated that, welded plates, bushes, etc. The thump changed, now it's very consistent, slip into first, release clutch and thud. Release super slow and no thud/thump. Mechanics here are pretty crap so perhaps he messed up along the way. The car runs great, puts power down perfectly, but that thump's always there. He now suggests there's play in the rear driver side axle (my car is a UK import Right Hand Drive) which is causing the thump. Living with it for now.

ok very good illustration ! Would like to See a road teat and conclude repair example ! Thx !!!

I found the easiest way to remove these bushings it to use a drill and cut as many holes as you can through the rubber bushing part. Then I used a a hacksaw or chisel to remove rubber and break the inner sleeve free. Sometimes we could beat out the outer sleeve, sometime we had to cut through it then beat it out. It is a slow process. Take your time.

The Polyurethane replacements that many are using are too hard and too expensive. I believe they are doing it because they come in colors. This car sits on the ground and we do not expect anyone to climb underneath it. The OEM Style were reasonably priced (kit) and are softer. If they last another 15 years.... that will be 14 years longer than we plan to keep the car. Just overall the better option for us!!!! You may have other needs. Cheers!

@lucase3047

Ok, understood. I replaced mine on my E36 then with PU from strongflex, they have a choice for slightly softer 80hsa. I believe the flex in the rubber will cause the jerking and that causes the metal fatigue... plus the pu stuff is easy to install and i never had a sqeak at all. I'd advice at least the diff bushing to be upgraded as that one puts a big load down. But i guess your right under normal circumstances oem style should hold for another 10 years .

I have an issue when I put it on R then brake I hear a loud clunk "sometimes not every time" I checked the subframe and there's no crack on the floor pan ! I have 3 things are possibly bad 1 Driveshaft (CV joint to the diff ) 2 diff bushings 3 subframe bushings !!

Yes the three things that you mentioned could also cause noises and you should investigate them. Just because there are no cracks in the floor pan does not eliminate this as the issue.

Here is a link to the location in my video were I talk about the three spot welds... kzread.info/dash/bejne/qnqckpRuZbW3d8o.htmlm3s.

why did you add spacer to the cross member?

@UCanDoIt2Mike

6 жыл бұрын

Part of the Turner Motor Sports Reinforcement Kit are plates that get welded to the chassis at each of the 4 corners of the subframe. The outer 2 ends of the cross brace will "land" on the front two plates. Therefore the cross brace is lowered by the thickness of the plates. The Spacers that you mention (6:26) are to adjust the center two mounting point by the same thickness. So basically the cross brace has 4 mounting points and all four were spaced so that the geometry was maintained.

Typically when to take apart any rotating assembly, it is wise to re-assemble them in the same alignment that they came apart. From what I read and other videos that I have seen on this a similar repairs, it is stated that you need to do this to maintain balance. It would be my technical opinion that BMW balanced all of these parts individually and at the factory, they are then simply put together and the balance is maintained. Personally, I do not think it is necessary, but I did not want to leave it out of the video and get criticized for it. It is easy to do and we did follow this during our build. Good luck with yours if you are planning to do this. Stay Patient!

DO NOT TRY AND WELD INTO THE EXISTING METAL. we welded a gusset plate to tge under and top side if the frame. pain in the a$$ !!
