Not sure why you are trying to use a spring compressor? Anyway, the easiest way i found way to first jack the KJ up,remove the tire, Loosen the clevis bolts that are clamping around the strut(may need to disconnect the clevis forks lower bolt as well, can' remember) Disconnect the UBJ (upper control arm at the ball joint, BFH....Bang!) Ensure something is sitting under your lower control arm before you disconnect the UBJ so the disc doesn't hit the floor
! Then you should beable to work the clevis fork off of the srtut and get your conduit nuts in there. You may also need to remove the swaybar( I did)
I'm not the best at explaning these things but i gave it a shot anyway. Good luck. Anyone pls chime in if i missed something or added something you fell may not be needed.
....I did my clevis lift in a driveway with basically next to nothing for tools and had it done in less then 1.5hrs (in the rain).
