There are five grease nipples.
One on each of the three propeller shaft universal joints and one on each slider.
You may well need to use a U/J grease nipple on the sliders which
don't have them screwed into the holes as standard.
There are none anywhere else.
Is there not a nipple on the top of the steering arm under the drivers wheelarch? apologies for late thread, just bought a disco and wondering where all the nipples are, looks like one there
