Just that you will need to take the track bar off before you can start putting your new links in. And when you start putting together the new links, put in a new top link first before you take the other top link out. Then take all the others off. Then put a bottom link on the other side and set the castor angle, then the other top link and then the last bottom link. You might find you need to move the axle sideways a little to line everything up. If you have Johnny Joints in them, put the bushing end in first then move the end to the frame and install.
