Like the perch, it seems the sealant acted as a water retention, creating pockets of water that stays and rust the frame...
Is this as bad as I think? Or its a "norm"?
As Olly asked me once about the clunk I got , look at the rear subframes bushes, the bushes look OK to me, but the attachement not.

More welding! Olly would know too, I think he became the rear frame bushes specialist...
 
eek! sorry to see this Olivier! Hope you can get it sorted!
 
It is not looking too good. I poked it this is why its looking worse but still...
Thanks Silver Saloon
 
I need some advice here on what to do, anyone?
Can I drive the car or its really not a good idea and dangerous? I use it everyday and need it.
Cheers.

Now that you are aware of the rust I'd suggest that driving it was irresponsible.

Should you be involved in an accident these pictures could very easily cause you problems.

Why not run it down to your local MoT tester and ask him to have a quick look at it?
 
It passed the MOT 2 weeks ago.
I don't think the MOT are able to tell or not how it is. Another member here not long ago pass the MOT and 2 weeks after got a front perch failure...
And to go to the MOT I need to drive there, then the "driving was irresponsible" was not necessary, especially I don't know how bad it is as this is my question as well.
Cheers.

I wasn't having a dig at you :)

If it were me, I would ask my local MoT tester to have a look at it now that you have removed the sealant and exposed the rust.

Have a go at the rust with a wire brush and see how deep it is - if there are any holes you know it's not too good :(

My gut feeling is that you are going to need a bit of welding though - you can probably buy replacement panels that will go in without too much trouble although they don't look as though they would be too hard to fabricate
 
Thanks Andy.
I poked it with a screw driver, this is why there are flakes on the the bush. There was no apparent hole that I could see so far?
Is the bush attached there to the frame/ chassis or it just rest on it?
Cheers,
Olivier
 
I would try to get a soft wire brush on a drill and run that on the rust . This will give you some idea as to how bas the rust really is . It might still be ok , and will just need to be treated and resealed . Hope its not to bad
 
Hi Shory,
Thank you for the advice. Its alot "flacky" though...
Now, does the frame rest on this or the bush is srewed in? If it rest on it this is not that bad I guess, but if its hold in place by a central bolt , I guess this is when it start to be a little spooky.
 
I would guess that its bolted in , you might have to drop the whole sub frame from the car to get good access .
 
Item 20 rear axle mounting front, not sure if one of suspension arm mounts or the subframe mount that you are looking at.

Just one big bolt through the middle, of the bush into the chassis.

You can remove the two front bush bolts and the front of the subframe will come down a couple of inchs for a closer look.

It looks like the rusted part of the car is not a small peice , but is part of a larger section 14 , and 17 . Guess it would be a case of cutting a small area out from the car and welding os a repare section , if the mount is indeed rotted through
 
It look like 20 or 14 and 17 as Shorty said.
Its a whole piece.
cheers.
Olivier
 
even though you'll end up buying the whole section there is no need to use all of it - find the extent of the rust, cut out the affected section then use the new panel to fill the gap.

Once the sub frame and the plastic trim are out of the way, that doesn't look like a huge job
