    Default Check out the damage to my BX 16 valve front subframe

    Hello everyone, I purchased my 16 valve BX around 2 years ago with a known subframe issue.I've basically just stored it since whilst waiting for it to be eligible for historic registration.Well the time has come so I'm tackling the subframe repair/replacement.I got the subframe out today and the damage is worse than I was hoping for, but repairable, Of course it would be much easier to install a good used on if anyone has one?Otherwise I will just weld up all the cracks and then plate over the top for good measure.As you can see the whole thing has taken quite a lot of hits over the years.Please stand by while I figure out how to post a picture over 100kbBen

    Good luck with the picture. I can't even get them up any more with less than 100kb.

    What is going on???

    Well either the forum is broken (or possibly my internet is being difficult)No matter how many times I try to edit my post for layout and spelling etc it won't save it, or just reverts back to all bunched up with no paragraphs etc.And it won't let me click on 'Go Advanced' either.StrangeBen

    How does that happen?

    Has the car been involved in a major accident or something? Surely it is not fatigue.

    Well that's the best I can do for now, the previous 3 links. They work for me but I don't know if you will be able to access them. If not let me know and i'll try something else.It looks like i'm completely unable to edit or delete my posts, not sure what's going on there.Plus the forum seems to only load a page 50% of the time, but if I hit refresh it usually comes up.Ben

    Looks like I can't reply to peoples specific posts either...Dano, I wish I knew how it happened.I'm almost positive it's never been in a crash.The car has fairly low kays for it's age, 150,000 iirc, and is pretty straightI'm guessing one of the more substantial hits on the subframe started a crack and from there it just spread with fatigue and stress.It must have been making some nasty noises for some time though, with the front wheels slowly gaining more and more toe out as the chasm opened up haha.Ben

    I can see three images, but there are obviously some problems with the forum at the moment. Simply fatigue? Not helped by the damage from being jacked up under the middle. I'm not sure if that's the right place to jack a BX in any case. It may have been torn in one place and the PO simply kept going, not realising how extensive the cracking was becoming and how quickly it propagated. The wheels were obviously still on, so it must have been just fine!!!

    Maybe the disease that ate your BX subframe is contagious and effecting AussieFrogs.John

    That sub frame is a throw away. If repaired it would never get an engineers certificate to allow for a RWC. Buy a replacement and then check it for beginnings of the same situation. I have never seen a Citroen sub frame in such bad condition. Is it the same unit in the Peugeot base platform?

    I don't think you could ever be sure that the wheel alignment using that sub frame would be close to correct. So I think you should replace it with one that has no cracks in the metal and isn't too bent on the bottom from poor jacking attempts. Cheers Ken

    There isn't a hint of corrosion in one of the photos - that damage came from impact which means all of the metal has had it. New sub-frame required (and check the seatbelts at the same time because they're probably stretched...)

    Maybe the wheels hit a deep pothole - looks like the stress loading is pretty even from one side to the other..? So check track-rods, etc as well (basically, anything outside the body that could have taken the impact from the wheels).

    Good grief, what a mess.

    Throw it away. There must be a BX somewhere that can be a donor.

    Denton at European Autocare Penrith might have something hiding in the graveyard, or check this out, https://www.chevronics.co.uk/product...ame-bx/someone somewhere will be able to provide one, there must be a few with some grass growing through them.

    having real problems posting, what is going on? won't let me edit or delete post. Just freezes up...the part at Chevronics in UK is in sub menu of BX parts suspension, used part and I guess the freight would be a tad up there as that subframe would weigh 25 kilos? so about $400to send at a guess. About $7-800 all up possibly?
