WRONG! You shouldn't need to pull it until . . .
If you remove the steering wheel, you will notice a factory NOTCH/GROOVE on the spline. That NOTCH needs to be at TDC. This ensures the steering wheel is STRAIGHT. Then go underneath where the collar is, and the pitman arm should be sitting at 90 degrees (straight front to rear). There is also a NOTCH on the steering box spline that should be at TDC in parallel to the steering wheel NOTCH. If it is not, then adjust it to where the pitman arm and the notch at steering wheel are at TDC. Once you align that, you should be fine. If the notches DO NOT ALIGN at this time, then you remove the pitman arm and re-adjust to that NOTCH (90 degrees). Adjusting the collar should get you there without issues because that pitman arm was factory set. So adjust it to where you have an equal amount of threads on both sides of that collar and check the NOTCHES at steering wheel and pitman arm. Once you understand what I mean, you can accomplish this on your own. Regards
