Frag,
I just got done replacing the 4 struts on my 92 Legacy. This was the first time for me. Some problems to look for that the Haynes manual doesn't mention:
1. Make sure you note the position of the upper spring seat before removal on front struts. Mine had two holes which need to face outward, torward the two strut-to-knuckle bolts.I neglected to do this and the strut didn't fit back up into the wheel well; strut touched the body.
2. I had to make my own tool to remove the damper shaft nut while holding the shaft with an allen wrench. The universal strut removal tool I bought at the local discount store wasn't the right size. An impact wrench would work too, but I didn't have access to one. Also, the shaft nuts on my original struts were 17mm, and my new KYB GR2's were 19mm.
Other than that, it was not bad at all.
