in sorting out n/s camber by adjusting lower transverse arm (has an adjustable inboard rose joint) this has thrown the tracking out.

Two questions.

1. To adjust tracking toe in/out can the steering rack end be turned after loosening the lock nut on the track rod end, or should the track rod end be disconnected and turned in or out? Hawk Herald rack.

2. Adjust castor is the solely by adjusting the bottom leading link (adjustable rose jointed)??
