Steering gear box centricity

Rough tie-rod adjustment on the left side at Kobe Kinki Department of Motor Vehicles destroyed the centricity of the steering gear box arm resulting tire hitting phenomena in right tire house of VW 1302 Super Beetle while a measuring for the other day's inspection test. This is mainly caused by the irregularity of steering link operating range because of the steering gear box control arm angular difference. In addition the movement limit stoppers on idler case construction were not adjusted well from the beginning. As a conclusion, tie-rod adjustment should be performed with the condition of fixing steering gear box control arm centricity, As I mentioned before, precisely established frontal wheel alignment should be the key to a following rear wheel alignment, total toe and it's direction, thrust angle that is the most important geometric alignment for stable driving. 1 mm toe-in would be applied under minus 20 minutes camber inclination.
About the steering box part for right steering position design, no further parts supply in the world is done, so the death of this part means the end of right steering 1302 and 1303 Super Beetles. I have already obtained this gear box as a replacement parts, used but no symptom of wear. Steering movement stopper construction is formed on gear box case for 1303 parts, instead on drag link for 1302.
