I recently finished installing a 4" lift in my Bronco, and took it in for an alignment. My Bronco has had a tremendous amount of steering play for years. I put a new steering gear in it 50k miles ago, so I knew it needed an adjustment. However, the alignment shop found a number of other factors that, once repaired took almost all of the play out of the steering:
Bad upper and lower ball joints on drivers side
Bad drag link pin
Steering sector adjustment
After this work was completed, I went from having a good 3" of free play in the wheel to about 1/2". The tech at the alignment shop said that the remaining free play is inside the steering column.
