I got blue ones from Bearmach - my view is that they are bushes, therefore they should give a little otherwise I might just as well weld up all the joints!!!

Interesting diagram Ricahrd - wish I understood it :wink:
I think when I get mine done - probably in the spring or when I get the winch for the hole in the front bumbper - I'll do the lot. Which of course means waiting until I can afford it...
But surely, doing things in this area bit by bit isn't wise? Won't the bits then just wear out at different rates and b****r up the replacement schedule?

I don't believe that for a minute Tina, a very intelligent Lady like yourself ought to see the link contents for what they are.
It's simply a sliding scale of relative hardness/softness & the consequent items longetivity.

For example;
Shore A; the elastic band is a 30, it doesn't have to have a life/service expectancy.
The tyre is a 60, it has to be able to grip the road surface (not too hard a compound) and provide an economical service life.
That's unless it's needed for a special application, ie; Formula 1 ('the drive round in a circle gang') the slicks have acomparable rating to the pencil eraser(40)

Hope that's reasonably clear :)

Great little drawing, unfortunately it still doesn't help me remember the colour coding  :wink:
