Great photos. Really helps, these are the chassis 'legs' though aren't they?

Looks like you have found your answer Simon. Are these the bits you want fixing? How much do you think it will cost? Got to confess until recently, yesterday, I did not even know the chassis had 'legs'. Let us know how you get on wont you? Thanks.

Yeah, it is what most describe them as..... It is possible with a mirror and a light to look behind the subframe and see this area...

Could also be the reinforcing panel right at the front of the bulkhead, where it joins the floor. Passenger side had gone on mine.

1978 XJS no floor all rust, replaced the complete under body of car.

pic of body upside down,, makes fitting and welding much easier!

From what I can gather that fits the description my garage gave to me. Right in front of the bulk head then going down to the chassis. Can it still be repaired by "just" removing the subframe or is it more involved than that?

some people in power UK , said to add some powdered ACID to the salt, it will melt the ice faster!

also called Rapid recycle program.

Yes. Worse, it's rarely cold enough to slow the process much. (We don't get much below 0C (32F) so the rusting goes on and on.)

That looks awful. Did this cause the 'clunk' whilst turning you were talking about then? Was it a clunk or a crunching metal on metal sound?

No, the clunk was a suspension bush, I just happened to find this when I took the subframe off.

A very nice job, I am soo glad I don't live on that side of the Pond any more, I had forgotten how difficult it was to remove Bumpers and suspension parts etc. I was shocked to see those rust Pics. My 1999 XK8 with 80,000 miles looks like the day it was built underneath, I have been very spoiled living in Southern California for 35 years.

I went all along the rusty areas jabbing away with a sharp screwdriver but couldn't find or create any holes, nor did it flex or sound soft.
MOT was done in August so I doubt the testing station would remember exactly what caught their eye and I don't want the expense of insuring it just to take it for another test.
Hopefully someone will recognise the rust areas and be able to give me some advice -






(Above) Bracket and chassis securing front of rear subframe, well rusty but no holes and sounds solid when struck









(Above) Sills and wheelarches rusty but again no holes and stabbing with a sharp screwdriver doesn't create any (floorpans have been patched at some point)

Is it likely to have failed because of the appearance of rust and as there are no holes could I just remove the rust, treat what remains and paint?

Mark

Rear suspension mounts both sides , bodged bought s type with 11 months mot on it took it for test failed guy at mot said it should have never passed last mot I contacted the mot station were it was tested , it was shut down by DVLA , just a petrol station now cost £1800 and a week to weld and sills as well !


, I love my s type full mot now no recalls
