I have a 300tdi 90, with 24 spline axles, i have adjusted my sterring lock for better turning circle as i compete in rtv trials, i use 7inch 0 offset modular wheels, with 235 85 tyres, and i am unable to get anymore lock, my caliper touches the axle casing before the tyres rub the radius arm, no one can quite work it out, but thats the way it is........ i have yet to have any CV issues, but time will tell!..... one thing i never do is use much throttle when on full lock......!
