Every component of the Jaguar steering rack was reverse engineered and CAD models and engineering drawings were generated. The racks and pinions were rough machined, stress relieved, re-machined and sent for gear cutting. The Jaguar rack has a helical gear form. The racks were ground to final diameter and then the teeth were induction hardened.
The Jaguar rack has a fine tooth vernier adjustment to remove backlash after assembly and to take up wear during the life of the component.
There are over 20 different components in the final assembly. Many different manufacturing techniques are used to manufacture the assembly.
