Basically jacked the side of the car as high as I could to make the suspension drop to max.
Then just pulled the dust cover down and then you just got to free up the rubber bung it will then spin on the damper and you can pull it down to apply the grease. Just case of aligning it back properly when done.
My bung was fine dirty but not split or anything. The underside of the mount had a bunch of oxidasation as well combination of this seems to resulted in squeeks.
Done over 1000 miles now and no noise
. Seems copper grease is the best option in my case
Arb bushes are not making any noise in my case so have left them alone. Car currently on 49K
