After parking my X in the driveway I heard a hissing and gurggling (sp?) noise. I looked under the back and was dumbfounded to see my shock pissing out fluid right above the lower bolt lug. Yes, i checked to see if itwas coming out of the piston cylinder seal. Everything above the lug was dry. I have not offroaded in months nor drove over any moderate pot holes. What could have caused this? Next day, I found the shock completely separated from the bolt lug. Obviously the lug was cracked, but why? mike
