Undo lower bolt, then the actual rod end will come out of the hub, you will need to lever it out as it will be stuck tight
i use a hammer and wack the hub part (not the track rod end) it will jolt it free
then u need to back off the locking nut on the threaded bar, once this is backed off you can remove the rod end.
to remove the whole rod, you need to remove the bbot, theirs a further bolt to remove on the inner rod and this will release the outer rod
not hard to do
