stock suspension and axle servos

[XCUTIONER]

right now i am having probles with the steering on my stock clod
for some reason the front wheels will not turn when it is on the ground, and moving, but if i stop the truck and pick up the front end it will turn with no problem

also it turns more to one side than the other

i have tried to crank down on the axles mounted servo saver and re-adjusting the servo horn but that did not work

has anyone setup an axle mounted steering servo on the stock suspension setup

from what i can make out the stock springs are in the way of mounting the servo mount of the axles brases like most i've seen
