It will be very difficult to remove the bushes in situ.

However if you tap in a half inch thread followed by a half inch bolt and a really big hammer you might if you can brace the spring.
This method works much better off the car on an anvil.

Thanks for your input everyone!

I'm afraid I've got very basic workshop tools at the moment! I will be buying myself a big vice at some point so will be able to try that out soon. I can lay my hands on some G clamps so could attempt the vice method with those.

To be honest my whole front axle needs a rebuild, so its looking more and more likely that its going to have to come off!

Thanks again,

Will

A big vice and an even bigger hammer are essential pieces of equipment you will need for overhauling the precision clockwork mechanism that it is now your privilege to delicately manipulate.

In my limited experience it is much easier to get the bushes out of the spring than the axle...
