You ever thought of doing this Simon?

I also wondered if the bushes for the front arms are the same for the rear? If so, what do people think of using front castor correction bushes in the rear?

Why would you need to castor correct the rear axle? Given that the rear axle doesn't have castor...

I have thought about it but never gotten around to doing it. Ive got radius arms laying around here and the bushes look the same to me.

Bigjon, its to alter the pinion angle.

Ok, probably not the best term to use.

As far as I understand, the caster correction bushes on the front are just rotating the diff/axle back into the correct position. I was wondering if you can do this with the rear as well.

The rear bushes seem to flog out fairly quickly when you have a half decent lift. Mine have gone and I am just trying to work out a way to get them to last a bit longer.

I'm not sure what the solution is for maintaining flex and getting longevity. I've only ever used OE rubber bushes in the radius arms. It'd be interesting to see how the SuperPro ones stand up. There are street and comp spec ones, I assume the difference is in the hardness, but that brand get good reports for selecting appropriate poly to maintain flex. .

These are cranked and Castor corrected. Use any bush you wish.
I have a set for the Defender front and rear. Excellent quality from a company with a good backgound and reputation. As usual the Oz suppliers freight and or attitude plus the initial outlay made the decision simple.

As the D2 rear setup uses a different style bush system to the earlier LR a cranked rear arm isnt necessary for bush longivity.

Thanks, yes they do the front, but I disagree about the bush longevity, mine and many other people flog out the bushes too quickly.

Simon, I have always gone for rubber due to the limitations of poly to flex.

I think it is all a bit hard at the moment. I will just replace the bushes and leave it for now. Maybe in the future I will go with the 4 point rear end.

I am looking at some modded arms for the watts link which will give another 2-3" of flex, but again this will just put more pressure on the radius arm bushes.
