There are only six, assuming that your vehicle has all the nipples it should. Many vehicles left the factory with fewer than 6 nipples, and there have been various service actions about replacing propshafts if your vehicle is deficient in the nipple department, but it is doubtful anything will have been done unless you've asked.

Each propshaft should have three nipples, one on each UJ and one on the splined extensible coupling (this is the one most commonly not fitted).

The correct way to grease them is:-

1. Disconnect propshaft flanges from gearbox/axle (or at least one end of propshaft)
   
2. Clean nipples
   
3. For each nipple in turn, inject a couple of shots of grease with greasegun whilst articulating the joint to distribute lubricant
   
4. Wipe off any surplus grease
   
5. Reattach propshaft
   

It is easier if you raise one wheel of each axle in turn very slightly off the ground so that you can rotate the propshaft when either greasing or unbolting it.

Emboldened by the valuable information above, I decided I’d have a go at doing mine today. It was a bit tricky dealing with the fasteners even with the special prop shaft tool but with a little patience and perseverance I got there.

Coincidentally, I’m slightly puzzled by the 3 handed grease gun references? Unless the nozzle of the guns used are not the collet type? My grease gun is a normal standard size cartridge gun. With these, before first use, you just need to experiment with the nozzle setting, screwing it in or out until the tension is set. Then with slight downward pressure, the nozzle clicks onto the nipple and happily remains there as grease is pumped. A gentle pull at an angle and the gun nozzle detaches from the nipple. Job done and with only 2 hands

Anyway, I’m indebted to Blackwolf and many others here who take the time and trouble to pass on advice and guidance on so many aspects of Land Rover ownership and maintenance . Thank you all.
