I must've been the lucky one: when I replaced my steering box the big problem was undoing those lines, had to buy a 3/8" drive crows foot to use with long (2 foot?) extension I had, so the ratchet handle could turn thu' 180* Curiously, I have no recollection of refitting them, apart from using usual care to start them by hand, although I seem to recall that it's important which one you replace 1st & you should only just start it, before replacing the other one.
