I know we are talking Marquis here, but just to hopefully add a bit to the thread, my Monterey lube instructions mention at least 3 fittings inside under the steering post shroud. One may feed the box below, though it says ours should have a zerk on the steering box; but I haven't personally tackled the job so am just speculating these may mostly be U-joint zerks. The steering post zerks may get overlooked by most owners, and perhaps service techs I've trusted regular chassis service to.
