Thanks for the info, looks like previous owner fitted them. I am looking to soften them as the pot holes in our area are ruining the pleasure of driving the car.
Are your leaf springs well lubricated? (motor cycle chain oil does the trick)
Following advice on TM I bought some of this at my local motorbike specialist
https://www.ebay.co.uk/itm/334650441499It is white, and unlike the (purple) ACF-50 that I have used previously, sort of sets into a gooey layer. As I don't have a hoist I did the job from above, with the folowing notes:
1. cover the garage floor (I used a decorator's plastic sheet) as it WILL run all over the place
2. I used a long / angled brush (like for painting the back of a radiator) which gets the grease into all the nooks and crannies
3. the 200 ml size can was enough to do the job and leave enough for next time
4. the result after 24 hours of waiting for the lubricant to penetrate thoroughly, was a satisfying improvement in the rear springiness.
