Are you trying to do this with the whole assembley still on the car? I assume at least, if the answer to my previous question is yes, that you've removed the rubber donut?

Yes jammy sorry if the OP wasn't clear. I have removed the rubber doughnut and sawed the trumpet so theres just like the lower third of the trumpet left in. I'll go take a photo.

If you are putting new cones in, you will need to remove the upper arm. I am doing my suspension at the moment and after removing the knuckle and trumpet I couldn't get the old cone out, never mind a new one in!

Taking the arm out is easy (although fiddly), on the pivot arm undo the rear most nut, then undo the little (7/16ths) bots on the front. Once you do this, the pivot will slide forwards and the arm will fall out. If nothing else it should be easier to work on!

Cheers for your advice. Grr just doubled the load on my mind though - got to sort out the back ones too now. wish I'd done the front first as I would have been able to see what I was doing and new exactly what to do for the back. It's just you cant see the cups on the back ones its so dark so it didn't occur to me then.

Where abouts in Sheffield are you? If the weather behaves tomorrow I will hopefully be on the road by tomorrow night so I may be available to come and have a play, and I have 4 spare knuckle cups that came with my hilo's if you want a couple.

You should drill a hole in the plastic cup before trying to get 'em out as there is a vacuum underneath. Why? because the air hole underneath is rusted up and you will have to drill it out to get the new ones in

I'm up in Totley mate If you fancy coming and seeing my mess and helping me if you could it'd be much appreciated. I'm not home tomorrow but I think I will be wednesday night. Those knuckles might come in handy for the rear ones! I have a feelin at the back I'm going to have new knuckle joints wedged into old nylon cups wedged into the subframe

Where can you drill it from? Would you have to drill it from below upwards? :S like through the top suspension arm?

[minimender]

Can't see what the problem is getting old nylon/plastic cups out of top arm or rears.
drill small hole in bottom of cup in the centre. Below the cup should be a hole right through the arm to let air in or out when changing cups. This will be blocked and that is why you can't get the old cup out. (vacuum)
Then drive a medium sized flat blade srewdriver down between the cup and the metal arm. twist and lever until the cup breaks up. You can then lever the rest out quite easily with long nose pliers.
Clean out the arm and redrill the small hole that goes through the bottom of the cup 'receiptor' to let the air out when you put the new cup in. Jobs a gud un.

One top arm, complete with hole, just in case you were wondering. I didn't even realise it was there, the previous owner had also painted over it but now its open again!

My car should definitely be on the road by Wednesday night, I need to be in Cambridge by 2am (Weds night/Thurs morning) so your pretty much on the way. I will let you know how my car gets on and will pm you if I can make it

Ahh cool didn't know that, looks like I'll be removing the top arm then drilling a hole and taking out the remains of the trumpet although nothing ever goes as simple as that with my mini/me!. Oh and the reason it'll be so hard to get my rear ones out minimender is because I rammed a knuckle joint (complete with cup) into an old cup that was already in place like a complete not going to forgive myself for that one.
Thanks a lot langers2k

Here's some photos of my front trumpet mess as it stands:

I once drove back and two to work for a couple of days with a lump of wood wedged in there when I broke a trumpet on a Sunday Night. Don't you do it....But it held

[langers2k]

Couple of options spring to mind.

Drill a hole through the remains of the trumpet so you can stick something through it and lever it out.

Blow touch/cut/hack away at the old cup remains so there is enough room for the ball joint to slip out.

Maybe even both together!

heat souds good, if you get whats left of the metal very hot it will melt its way out of the plastic cup with a bit of levering

Hmm I was going to try taking out the top arm drilling to break the vacuum and put it in a vice and take it from there. Because you can't really work with that bit of the front subby in the way ('bulkhead'?)
Cheers for all your help guys I'm going to take an early night gotta be at work in Bradford at 7am tomorrow. Will pick up where I left off tomorrow if I can

Before you put the suspension back together you'll need to fit a new bump-stop as they fit with a bolt which goes up towards the rubber spring and are almost impossible to fit when the spring & trumpet are in place, although that's the least of your worries at the moment! Heat sounds like a good option to melt the plastic cup - good luck with it!

Im amazed you got the cone out like that.... you havnt even removed the bottom bump stop.... Im in with the ..'remove the arm completly'... concensus.
