Trying to replace the rod bit that the track control arm winds on to on my mk2 mondeo. This rod bit then bolts into the main steering rack. I've got the boot off and have it on full lock so that arm is as much towards me as possible.

But I cannot crack off the rod from the steering rack. Theres no nut on it and it is soo tight that I cant get it to budge with mole grips or a hammer and chisel.

Any suggestions?

Also does anyone know if you can replace the bottom ball joint (rubber boot split) rather than the whole wishbone?
