You have to remember that when you lift any vehicle you change the geometry of your steering components. Just because it was aligned before kit install does not mean that the alignment is still true. Also when ever you lift any vehicle any amount of free play in most components is exaggerated. What you may not have noticed before lift install is very noticeable afterwards. You can check the lower steering shaft coupling, if you have manual steering and now have larger tires you are applying more torque to steering shaft and gear box to turn larger tires which may cause a looses feeling in the wheel that was never noticed before, including flexing of chassis at box location. Ihad to heat, beat and pull like hell to remove my old pitman arm, your mam might have done the same as well. Someone correct me if I am wrong but there is a manual and power pitman arm depending on the box. Make sure that you have the correct one, they should not interchange but who knows.
