the main head is too small. I have a small truck old ford ranger and I had a lot of difficulty removing my inner tie rod and it's just a small truck so imagine suv or bigger f150 it might just not work at all. the head is too small the round end of the inner tie rod barely fits in it. i had to try like 20 times to remove and another 20 to install install mine just frustrating. the main head opening of the shaft is too small.
