Adam, yes the reason for jacking front of car up an inch or so to grease is to allow each wheel in turn to be moved easily to gain best access to the two nipples. Turned out at the front onto full lock you should easily see the top grease nipple on the kingpin top bolt. Ideally this should have been fitted to point forward. The lower nipple on the sliding stub axle is a little more difficult to see but is just visible on picture below of stripped down suspension if you zoom in, behind r/h side of caliper support and facing inwards.

In each case a few pumps of grease gun is required finishing job by removing excess grease that will have been pushed out usually from bottom of stub axle. An old long sock helps here. Finally clean disc rotor with brake cleaner.

Highly recommend this quick release grease gun fitting with flexible hose. You dont need to crawl under car to do this job but simply reach in to attach gun to nipple.
