the lockout switch, the mechanism transfers the rotational motion from the axle shaft to the rotor assembly.\u00a0 That allows the wheels to rotate in unison with the axle.<\/p>\n<p>Here&#8217;s what the axle shaft looks like inside the spindle.\u00a0 The spindle is fixed on the knuckle.\u00a0 The axle shaft spins concentrically.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone

shaft will rotate away and away and away without transmitting any rotational velocity to the wheel.<\/p>\n<p>The lockout hub just slides on the end of the axle shaft splines.\u00a0 IIRC, these are 35-spline axle shafts.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1455\"

front (closest to the lockout hub), the spindle nuts are a unique looking set up.\u00a0 The spindle nut WITH A NIB (see the photo above) must go back.\u00a0 Then the locking washer goes in the middle.\u00a0 Assuming you are securing the rotor, you&#8217;ll need to torque the back spindle nut to 50 ft-lbs, and turn it back a 1\/4 turn.\u00a0 Then slide on the washer with aligning the nib.<\/p>\n<p>Then torque down the front spindle nut to 150 ft-lbs.\u00a0 Once that is completed, there should be enough room to slide the Warn Lockout Hub.\u00a0 If you don&#8217;t torque it correctly, the lockout hub won&#8217;t have enough room to install the inner retaining clip.<\/p>\n<p>Be sure to use some high quality grease to ensure all your bearings, races, spindles, and lockouts stay in good shape.\u00a0 I always use Mobil 1 Synthetic Red.\u00a0 Never been a problem with that grease.<\/p>\n<p>Installation is the reverse of uninstallation.<\/p>\n<p><img loading=\"lazy\"
