So, as I lay there last night under the car (feeling despondent) the part number for the subframe was right in front of me....I checked on eBay and they are not expensive.

Suggestion
Many years ago I had to change my front subframe due to a snapped (ARB?) bolt or two, the crud build up in the threads of the upward facing bolts was so bad they didn't shift, it was like a valley where all sorts of road grime had got into and after several goes at getting them out they snapped.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I decided to renew most of the suspension on my car, and it went well - apart from the front ARB bushing bracket bolts..all 4 bolts are stuck into the subframe. :sad: (steel bolts into aluminum)
I've done all the usual stuff : acetone/ATF into them, heat, hitting, pilot hole then extractor...nothing works.
So, as I lay there last night under the car (feeling despondent) the part number for the subframe was right in front of me....I checked on eBay and they are not expensive.
It
looks
like and easy job to swap the subframe. Is that that case or am I missing something?
Thanks
edit : to clarify. Each bolt head has snapped off, leaving the mild steel bolt stuck in the aluminum subframe.
I could just take the car to my local OPC - but it's at least a 3 week wait and the labour rates here are insane. So replacing the front subframe myself would (should?) be the cheaper and quicker option..
I swapped one of my rears last year as it snapped where the coffin arm bolts on. I was quite surprised how easy it was. Just time consuming stripping all the suspension parts off.

Funnily enough I remember your post from last year, I was always terrified of snapping something on the subframe :grin:
Side note : in the winter I plan to fit solid rear subframe bushes...
Sorry, reading back my original post I wasn't clear at all - they have all snapped already.
Each one of them just pinged off. I think the triangle plate that goes between the bolts and the subframe has a lot of tension on it from the tuning forks.
Careful with Copper Slip, they do say it actually promotes corrosion between ally and steel (look online). I bought a tin of aluminium grease, cheap enough and it's a lifetime's supply.

It wasn't too hard to change and I favoured it to trying to drill the bolts out as the subframes are fairly cheap.
I got the subframe swapped over quite easily. One question....is there any special alignment that needs to be done?
If so, does anyone have tips/documentation for what needs to be done?
Thanks!!
