I just finished replacing the front struts on my LR3. The struts are rebuilds from Suncore and are as good as new.
Here's the video which has some very good tips found nowhere else as far as I can tell. The first is to remove the heat shields to access the top nut closest to the engine; the second is to unclip the air line to give more space to remove and replace the connection. I'd also add that you'll need a bottle jack to raise the strut when the air line is re-attached. This isn't technically difficult but it does take it out of you.
One last thing, don't make the mistake I did by failing to thread the line back through the guide hole before re-attaching. I was tired and it crushed the line.
