Are you using Skyjacker's? I just did mine a couple weeks ago and it didn't go as easy as I expected. The rear line has the completely wrong size fitting where it hooks up to the hard line running forward. I still need to call Skyjacker about that one... The fronts went ok, but the end of the SS line that clips into the bracket and attaches to the hard line isn't exactly a drop in replacement. Not too bad, but be prepared to massage the bracket and clip a little to get it hold on. Or ditch the bracket all together and support it some other way.
Not a bad install, just not completely drop in. Not sure if 4WP just sent me the wrong one for the rear or what... Good luck.
