Hi John,
Are you struggling with the inner or outer balljoint? I can't quite work it out even after reviewing the early posts.
If it's the
inner, I posted details in the Spring of a Sykes Pickavant articulated puller which turned out to be the perfect choice!
No heat, banging or dropping the subframe required!
If it's the
outer then I sympathise because I struggled with mine until, by chance, I discovered that the angle of the hub is critical. When I pushed the bottom inwards towards the gearbox the balljoint pin released, but you do have to push down on the suspension arm to counteract its springiness. Four hands are a distinct advantage.
