More or less yes but you cannot as easily access that nut with the strut in place.
The very easiest thing is to have an IIDtool and use it's function to deflate corners.
Just an update on my project:
I've noticed that 'projects' posted on U-tube seem to be a lot easier than they are in reality!
A few of the 'real world' challenges that I experienced (maybe my LR3 is unique??)
--One U-tube poster suggested relieving the air from the valve block under the passenger-side wheel well cover. It was a bit more involved than 'just a few little screws'. Depending on how much room you need to access the valve block, you'll need to pop out (and get replacements for) the fasteners that are used to secure and tighten the wheel well cover. I really should consider getting the IID tool for this, and/or reasons!
--This same poster suggested removing the heat shield above the strut to get better access to the 15mm nut closest to the engine, which is very hard to access. This is a helpful hint. However, I lost my grip on the nut, and it fell somewhere into the frame, never to be found again!
--The most difficult part came when I had to re-connect the air line to the strut. The line had a bend in it, which complicated an already difficult access. I finally resolved to cut the portion that was curved, so that I wasn't simultaneously trying to straighten it and insert it. There was no direct vision, and this was done by feel only. I had to pry away the wheel well cover on this side also, to access the air line, and remove it from the clip that holds it in place, in order to give me a little more length to work with.
In summary, I can understand why people have shops do this. In my case, it just seems like there's always that unexpected thing or two that presents itself to me...
