Loosen the bolt on the sleeve, remove the cotter key that passes through the nut of the tie-rod (if you can), if not, simply thread right over it, use either a fork or hit the cast iron on the spindle with a good size ball-peen hammer and get the tie-rod end out of the spindle. (By hitting the spindle where the stud passes through it will pop the tie-rod end out of the spindle).
Lube up the sleeve well and the tie rod MIGHT turn out, if not, you will need to heat the sleeve up. You will want to make an accurate measurement from something that isn't going to move, (like the end of the sleeve) to the center of the stud while it is still in the spindle. Re-install the new one to the same measurement as the original and you wont need a front end alignment.
Is that clear enough or are you still confused?
