ZX Track Rod

[VLL]

I've been changing both track rod ends on the ZX today, first one no problem, done in 10mins, second one different story, completely seized!!!

Have tried heating it but it still wont go, infact we managed to bend the arm without it even moving a mm. The locknut was seized too which i had to cut off.
I've just ordered a new track rod but having a look at the old one i couldn't see how it comes off, the ball on the end appears to be screwed in but how do you grip this without damaging it to unscrew it from the rod?
Is there a special tool for the job of just a big set of vise grips?

The track rod is a complete unit with inner balljoint. Its the inner balljoint you unscrew from the rack. And yes you grip on the large "egg" behind the ball. There will be flats on the rack to counter hold not to twist and damage the rack.
Boot must come off to do/see this.

Note : track rod type depends on year/model/engine/power-steering/not combination. Double check you get the right one !
