Title: Rear subframe / crossmember
Post by: Dan MR2 on February 23, 2016, 19:10
Hi, I've checked my subframe over when I brought the car couple of weeks ago and it seemed OK,  found no big rust holes underneath or on the top, but today I've felt along the back edge near the exhaust manifold and the seamed edge is quite pitted/rusty, my mechanic mate is replacing the manifold tomorrow so I'll get him to check the subframe when he's got the manifold and plastic tray off.

The question is though where can you buy new subframes from and roughly how much?

I would like to get one so I've got one to replace down the line, paint it/ treat it, etc.
I've done numerous search's on the forum,but can't find anything recent about where to buy one.

Thanks Dan.

I just rescued one.  rusted through in one place.  Sub-frame off, give suspect areas a bash with the ball end of a hammer to find the weak spots, cut out bad stuff, weld in new metal, wire brush all over, rust treatment on spots, remove rubber pugs and spray in waxyol, replace plugs, zinc primer and top coat of grey stone-chip paint.  I also sealed up the holes at the corners where the water gets in.  Some (I've seen pics) are too far gone, but if it's not too bad, it can be repaired.

That's good to know, mine could very easily be welded on the back end/side because the top and bottom of the subframe are solid with no rust,  I just would be concerned about the levels of rust inside, also I would have to pay someone to weld mine/remove and refit, so with labour costs plus welding costs it probably would be better for me personally to have a new one fitted if needed.
I could remove one myself but if I run into problems I can't have the car off the road as its my wife's daily driver, which is why I'm having the manifold fitted, incase the bolts snap!!

If it's not rusted through, a good paint and waxyol will preserve it. Even if there is rust inside, sealing it up to stop air a water getting in will stop it going further. No air -no water = no rust!!

Toyota no longer supports parts supply for these cars so a new sub-frame is very hard to get.  Yours sounds like you could paint and preserve without taking it off the car.  Then just keep an occasional eye on it.  Make sure it's strong around the suspension mounts.

I'm going to ring my local Toyota dealer tomorrow for availability and price on subframe/crossmember just out of interest, will let you know what they say.

Is the USA model going to be the same?.
for about £99+99p&p and possible customs (duty on the 99+inspection fee) you can get a rust free one on ebay from the USA.
 m http://www.ebay.co.uk/itm/161805350836 (http://www.ebay.co.uk/itm/161805350836) m ?

just an idea, as I guess these will all go eventually.

I got one from MRT no problems September last year.
Not only do they rust through but the camber bolts can rust solid too.
Mine had been welded once the stuck bolts were preventing correct wheel alignment so off it went to the scrapies.
A brand new one gives me confedence that looked after properly it will last me another 10 years.
Pretty sure it was less than 300 quid fitted powdercoated and treated.
There will be a podt somewhere about it.

I've rung my local Toyota dealer, ask for a rear subframe/crossmember for mr2, gave them my reg as well,
They said its £104 including vat for the subframe, widely available, can get me one in for Friday.
Does anyone know the part number so I can double check it that way?
Title: Re: Rear subframe / crossmember
Post by: jeffsimply on February 24, 2016, 10:37
The part you want is £300 from Toyota. They're looking at the wrong thing.

Odd...I asked Mr T in December same question.  £320 ish.  I don't think £104 is correct, but if so I'll have one at that price   s:D :D s:D

Price indicates the wrong part to me - too cheap.
Think this is the FL 51206A or 51206-17040
Your MrT should be able to email you a diagram with the part number from your reg.  Mine does anyway   s:wink: :wink: s:wink:
Title: Re: Rear subframe / crossmember
Post by: Dan MR2 on February 24, 2016, 11:18
They have just emailed me the diagram and I've spoke to someone there that knows more about the mr2, they have confirmed that the rear subframe is a discontinued part and no longer available!!
Title: Re: Rear subframe / crossmember
Post by: 1979scotte on February 24, 2016, 13:16
That is terrible.
The newest cars should still be covered under 12 year anti corrosion warranty if FTSH is present.
Last year headcase got me one no problem.
Title: Re: Rear subframe / crossmember
Post by: Dan MR2 on February 24, 2016, 13:32
I hope it's not discontinued, the person I spoke to said that he's worked for Toyota for 25 years and said he's never heard of a rear subframe/crossmember corroding?!?!? that's why it's discontinued, it's never needed!! hopefully he's wrong.
If anybody can give me the part number I'll try elsewhere, thanks.

These cars went past the Ten Year Since Production Barrier this year.  So Toyota will not be re-stocking parts.  Bit-by-bit re-cycling/aftermarket will be the only way for lots of stuff.  I've seen a pile of sub-frames at a breakers and they are all reusable.  We just have to get used to being a bit more creative!!
Title: Re: Rear subframe / crossmember
Post by: Dan MR2 on February 24, 2016, 17:59
My subframe has been checked all over today by me and a mechanic and thankfully is totally solid all over with minor surface rust on the back edge, which I've treated/sorted out.

If it is a discontinued item now, it doesn't look good for the long term future of MR2's, but they are a mass produced car so surely a aftermarket company should eventually start producing subframes, because there will be a market for them.

People are fabricating sub-frames from tubular steel and they are for sale.  But the moral here is look after the one you've got, I think.  They rot from the inside out because water gets in the top corners (up by the chassis rail) and then just sits inside at the bottom.  A good dollop of sealant in those holes will keep it dry.  A couple of small holes at the lowest point on both ides will allow it to drain.  

I'm pleased that yours is OK - good result.

TBH it does sound like you've spoken to numpties at Toyota. Try a different dealership. I'd be surprised if they discontinued it.
Title: Re: Rear subframe / crossmember
Post by: Carolyn on February 24, 2016, 19:48
There is no legal obligation for manufacturers to supply spare parts for a specific period.  The better companies do support for ten years, these days.  When you think of all the models and parts - there has to be a limit somewhere.

Toyota does its best for ten years.  There's loads of very old cars still running and on the road which have had most specialist parts discontinued decades ago. If you have pre-facelift it's at least 14 years old this year.  Bit bit, the new parts will dry up.

Not the end of the world, just time for a different approach.

I decided to do a bit of research and found this amazing website that's full of info on Mr2 Roadsters. It's at  m http://www.mr2roc.org (http://www.mr2roc.org) m !  In a previous thread in this esteemed website, one 'Goeman', in 2010, actually found out how many had been sold in total in the UK;
13,934!!! Over six years.  That's just over 2,000 cars per year.  There's not much of a market there to encourage Toyota to keep making and stocking
They're great little cars and they are getting scarce.
I'm for fixing and saving every single one,

That is very intersting.  They're tough little buggers to have such a high survival rate!  Though, I wonder how many of those registrations are JDM imports.

Hey guys, just got my rear subframe replaced today. Carolyn mentioned drain holes and plugs... I don't believe I have either! Where can I get some plugs from? Or can I just use silicon sealant?
And can anyone pin point exactly where drain holes should be placed? My new subframe is so pretty I don't really like the idea of doing holes in it!!
Title: Re: Rear subframe / crossmember
Post by: Ardent on February 24, 2016, 22:57
plugs - from your old one.
The holes will already be there. (or should be) I'm not sure they are designed as drain holes. Just holes. As the lowest point when fitted does not have holes for water to drain.
Quite happy to be told different.

This might help. some pics of mine before fitting

Thanks Ardent, I'll have to call up Luke in the morning to see if there were any plugs left... Don't think there were... Surely silicone will do for a while??
Title: Re: Rear subframe / crossmember
Post by: Ardent on February 24, 2016, 23:16
from memory, rightly or wrongly, I believe I have left mine out.

Water can get in easy enough, my thoughts were lets give a chance of getting out via evaporation. The exhaust runs underneath, so will be heating the sub frame up and the water inside, therefore lets give an escape route.
I also gave it a good covering of Bilt Hamber Dynax S50 on the inside so should be ok anyway.
This can be done insitu if required.

That does not look the same as the ones that I've got. Post face-lift?  

As for drilling holes.. if you have a preface-lift one, seal up the corners at the top and keep the water out -that should do it!
Title: Re: Rear subframe / crossmember

For clarity.
the one shown is a face lift version.

So how easy is it to seal up the holes after it has been fitted???
Title: Re: Rear subframe / crossmember
Post by: Ardent on February 25, 2016, 12:38
The longer your arms the easier i would imagine.
the bungs just push in.
sealing as per carolyn always going to be easier inthe air than on the floor
but doable either way
Title: Re: Rear subframe / crossmember
Post by: Carolyn on February 25, 2016, 16:35
Sealing the corners can be done on the car.  I ended up forcing it in with my finger - messy but it worked.  
I've just pried a rubber plug out of a cross-member. It does look quite specific for the car.  The hole is a shade over 14 mm in diameter.  You can get 14 mm 'blind grommets (solid rubber on the middle - no hole so those would substitute.  Better if you can recover the ones from your old cross-member, I think.  I would try and seal it water will pool at the lowest point at be very slow to evaporate.
Title: Re: Rear subframe / crossmember
Post by: jvanzyl on February 25, 2016, 16:55
Thanks Carolyn, I managed to recover a grand total of 3 plugs... I figure the rest must have just not been there.

I guess I'll have to see if Wickes sell a "grommet pack"!! Otherwise I'll have to see if I can fashion some kind of "bung" to then silicone around?.... hey... what about cork!!! surely that'd be a decent material.. no idea if the silicon would stick to it..
Title: Re: Rear subframe / crossmember
Post by: Carolyn on February 25, 2016, 17:08
Found these.  Might need a smear of sealant round the edge.

I collected my shiny new rear subframe from Toyota Nottingham today, £309 inc VAT. No problems with supply at the moment apparently. I will be keeping it locked away until I need it. Can't be too careful.....
Just need to decide on the best way to rustproof it.

Have you got the part number for future reference, or did they know what a rear subframe is unlike Toyota Derby!!

Part number is 51206-17040 but yes they knew exactly what part it was. To be honest I can't recommend the Nottingham Toyota dealer highly enough, they are exceptional. Much better than the Mercedes-Benz dealer I use for the other car.

Would some sort of heat shield between the exhaust and the cross member, where the exhaust runs close, help the cross member last longer?
