1) Install one side at a time so that one side can be used as a reference to measure against.
2) Start on the passenger side as this side is easier to cut off.
3) Begin by removing the passenger front lower control arm. Once removed, safely raise the vehicle to a
height that can easily be worked under. Allow the front suspension to hang free and safely support the
vehicle with a quality jack and jack-stands.
4) Next, take some reference measurements. Record several measurements. You should have 3 total
measurements before cutting anything:
