as above what is invloved in swapping from sierra to freelander diff, thinking about drive shafts diff carrier and anything else i need to think about.

prop end flange will need to be changed, conversion shafts freelander inners to sierra outers, new mounts fabricated

looks like thats not going to happen then, thanks for the info

you can buy or make adapters that go from sierra mounts to freelander diffs. But you would need prop and shafts modifying. Im sure a good prop company could swap the uj without too much effort!
