You know, that big flat one hat holds the strut insert in? Do you just buy the factory tool? My factory service manual shows it as a simple tool, should be relatively cheap. Sorry, I don't have an adjustable wrench with a 4" span, although I'm sure that'll work

 

what I used was simply a huge pipe wrench.
clamp the bottom of the strut in a vice, and have a helper brace the strut while you loosen the gland packing nut. (that's what it's called, FYI.

loosening the first ones will be a real PIA if they haven't ever been done before.. you'll most likely need a helper. also be sure to spray plenty of liquid wrench or wd-40 on it about 10-15 minutes before you're ready to tear them down. it will help immensely.
Good luck!

 

matt has a good idea there . the pipe wrench is going to be cheaper than the factory tool. you should be able to find a cheap on for less than $20
