This is a repair I've done more than once. I'm assuming you're good with getting the top panels off.
1) When you go back out with the parts, get your inspection mirror and look at where the strut hits the tub frame back in the back where the light is hard to see. These struts can wear out the tub frame and wear a hole in the frame, and you won't necessarily see it. If you do see a hole worn in that, I would decline the repair as not cost effective.
2) Unclip the drain pump and the motor's wire harness.
3) There are two bolts holding the base to the frame on your left and right hand side. These can be rusted into place, remove with care.
4) Unclip the drain hose from the clips at the back of the frame.
5) Unclip the water valve fill hose from the top of the tub.
This should now give you room to slide the washer assembly out where you can look at it.
The nuts holding the struts on will be really stubborn; you may need your rubber mallet as well as your wrench. Undo the 2 5/16" screws on each side of the bolt and you'll have room to work.
Work on one strut at a time.
The strut unscrews, but it can also be really stubborn. Last time I had to get a vicegrip on the base of the strut before I could get it into motion.
If you jumper the lid switch you can test all of this before completely reassembling.
If this is the first time you've changed those struts allow about 90-105 minutes. Might not take that long.
