Have a poke about through the hole , you are feeling for a grease nipple. A mirror on a stick is also useful. You might have to rock the car backwards and forwards a little to locate it. Then Get some high pressure blue grease from JCB, about £3 per cartridge.
If its rattling you need about 20 pumps from a side lever grease gun. That will sort it out.
Thanks for the advice, I did find a nipple, and once it was at the hole its quite east to get your gun attached.
As advised, the JCB grease is about £3, its in bigger tubes than I expected, I bought three if anyone wants one.
The good news, its 50% quieter it took about 2-3 miles before it started to work, I suspect it was getting "squidged" round its internal gubbins.
Definitely another worthwhile job, that is a doddle to do.
