looks like removing the drom arm in the morning then i have tryed hiting the hell out of it with a lump hammerBuster ended up taking the drop arm off, which is a pita.
I supported the drop arm from underneath with a bottle jack. Then, using a 15mm (I think) deep socket and a couple of long extension bars, I brayed the fook out of it with a lump ammer from above.
Basically, you need a long drift that fits through the top of the drop arm, but is too big to pass through the ball seat. However, if your ball seat is extremely worn, there may not be enough of a shoulder left to do it that way. In that case it's probably best to remove the drop arm.
i think yer missing the point, it int about getting the cup out it's the removal of the arm he's on about which is the problem!!! How can you lob the "damn thing in the bin" if it has a 2 tonne lump of rusty steel VERY firmly attached to it!?Well another option which I have used many many times is to make a home made puller.
Find a socket which fits through the drop arm but is wide enough to catch the top cup on its way through, Run a bolt through the drop arm and through the socket, Use some thick plate at the bottom with a hole in it for the bolt.
Tighten a nut on the bolt and keep going till it pulls the top cap out.
Another nasty way to get rid of the play in a drop arm is to place a 2 pence coin below the spring. It fits perfectly.
Or the best option of all is to lob the damn thing in the bin and get a drop arm off a 300 Disco. Use the 300 drag link and track rod and move the damper behind the axle like Disco/RR.
This way you only have to swap the track rod ends which is nice and easy...
