You need to get the tie rods out of the rack, persist to get them undone. Loosen them, then drop the rack, undo them completley (they will still be inside the rack but undone) pull one side (the hardest bit as there is SFA movement) then the rack will drop down and the other side will pop out.
Get the cancellor and screw one end in nearly all the way, then the other side. Dont do them up tight until you have bolt the cancellor to the cradle. Then tighten everything up and adjust ur toe.
Make sure you dont damage the thread on the tie rod ends where it screws into the rack.
