Frist thing to think about is, how long have the shocks been on there as they often prove very difficult to remove (well mine did) and i had to cut them off which means you may need some new shocks to hand, the rest off it, well it is a land rover so if everything undoes nicely you have the break pipes, propshaft, springs, shocks, and probably more as i have never done this, not sure if the brake hoses are different on a disc braked axle, hope this helps
