You don't have to pull the axles completely when you install an ARB. You only have to pull them out +/- 1", to disconnect them at the carrier, so you can pull out the 3rd. Which means you don't have to touch any brake lines, abs, etc., on the axles. There's enough slack in all the lines to pull the axles out 1" without hurting anything.

Other than that, yeah, it's about the same amount of effort.

Besides, people, no matter what type of spool you put into the X, you're STILL going to have to do all this, 'cause you have to remove the 3rd member. About the only real difference in the ARB install, is that you have to take the ring gear off, and put it on the ARB carrier. So you're talking a few bolts difference... Big whoopie.

If you don't have enough mechanical skills to take the 3rd out (aka, pulling the axle shafts out), you don't have enough skill to install a locker, no matter what type it is.
