Subframe removal

[16V F7R]

Isn that going to damage the subframe or chassis as I’m doing it, even with a 1mm slit disc?

Got that steering rack bolt out, went in through the side with arm through the wheel arch and also could get the bolt out the back inbetween the back of the subframe and the anti roll bar. That will be the best place to slide it back in. I am not looking forward to getting that back in.

Anyway I am just having to drop the subframe now, thank f**k. Well finally remove that linkage bolt and then carefully do it. However I have that one subframe bolt and the back that is not loosening and the nut is not being gripped by my 19mm spanner. The other side at the back is coming off and lowering the subframe slightly. So I think I am good with that one.

So what do you do when this bolt won’t come out? I don’t know if it is my spanner that isn’t getting the angle to grip the nut right or where do you cut it or do you get a long cold chisel and try and crack off the nut in the subframe to break it off? That nut and the bolt are starting to ‘dissolve’ as you say.

Thanks again to everyone who has helped with this.

I could be wrong but I’ve got 18mm in my head as the nut size

I’m going to try an 18mm I haven’t got one in my set. The other bolt at the back has been winding out but it may be just the way the spanner has been wedged. I’m getting a 18v grinder with a slit disc at the ready. I hope it will wind out a bit at least but the driver side bolt is proper corroded.

It’s finally off the car. I didn’t have to cut the bolt in question, the 18mm spanner fit perfect and I figured out how to get the angle with it and turned it off bit by bit with my ratchet. The rad on the mk1 can stay in and it didn’t need strapping up, they are bolted to the front cross member at the top with a couple of brackets. There was another bracket that needed unbolting at the bottom of the rad that connects to the subframe though that I didn’t realise until I started dropping the frame. The power steering pipe was awkward (because of the hard pipes) but managed to get that manoeuvred around as the frame was being lowered. The gear selector arm was the worst thing hindering what could have been a straight forward drop. As you have said that rod arm is weak so I constantly had to be careful and turned the frame at an angle in the end to get it out. I had to use two trolley jacks as well. Ideally it would have been great to have had an extra pair of hands. Putting it back in is not going to be easier and when everything is freshly powder coated I am going to have to probably get someone to help me get it bolted up as it was very awkward man handling the frame and the trolley jacks at the same time.

So what do people recommend me to do with the frame, bars, have it sandblasted and then powder coated or sandblasted and paint?

Thanks again for your advice.

Depends what the end result you're after looks wise is tbh, on my Williams I was after as close to OEM finish as possible so went with paint

But on my track car I wasn't bothered about looks/finish & wanted something durable & cheap so went with gloss black powdercoat

I’m swayed towards powder coating for the durability and I like the gloss or satin black finish.
