the track rod end can be replaced but it can be very difficult to unscrew the cap the retains the ball of the rod end

often the easiest route is to remove the entire rack so it can be held securely in a vice

and on some models there is scope for adjustment by removing shims to increase the preload onto the ball end and tighten it up

on others the ball end and track rod are one sealed unit that screws into the rack end and its secured with a locknut

I'd suggest getting in touch with a steering specialist to see if spare parts are available for your car or they 'll do a an exchange rack which will be chepear than a new rack
