The one that cudu_jim posted only applies to the manual lockers. The autolockers have a whole different setup. there is a large hub nut that requires a hub socket to remove after the autolocker assembly has been removed.

Sorry darth, Didn't see you gad autohubs. You may want to trash the autohubs anyway, they'll break just when you need them IMO.

Here's the autohub instructions:


CAUTION: Do not drop hub components during removal and installation.

Separate cap from body assembly by removing the three capscrews from the cap, using Torx® bit TX25 or equivalent.

Remove cap.

Remove the lock ring seated in the groove of the front disc brake hub and rotor.

Remove the body assembly from the front disc brake hub and rotor.

Remove C-washer or snap ring from half shaft groove.

Remove spacers (three thrust washers) from shaft. Remove cam assembly.

Pull to remove.



1 Cap
2 Hub Body
3 Snap Ring
4 — Plastic Thrust Washer
5 — Cam Assy
6 — Wheel Retainer (Nut)
7 3B549 Wheel Retainer Key
8 — Steel Thrust Washer
9 — Splined Thrust Washer
10 — Lock Ring
11 Capscrews (3)




Installation
Align the fixed cam retaining key on the cam assembly (garter spring inboard) with the keyway on the spindle. Firmly press the cam assembly on the wheel retainer nut.

CAUTION: Improper sequence of three-piece thrust washers will result in excessive wear of assembly.

Install three-piece thrust washer set (first metal, second plastic, third splined) and snap ring. It may be necessary to push the axle outboard from backside of knuckle. Be sure snap ring is seated in groove properly.

CAUTION: Rotate moving cam stop (use any one of three) to the one o'clock position in relationship to the fixed cam retaining key.

CAUTION: Do not force body assembly into front disc brake hub on rotor if body assembly will not fit. Recheck alignment of all components.

NOTE: The hubs should not be packed with grease. Too much grease will damage the hubs and prevent proper operation.

Install body assembly into vehicle front disc brake hub and rotor by lining up the three legs outside the hublock body with the three pockets in the cam assembly.

Make sure body assembly is in far enough to see groove in rotor tube. Install large lock ring into groove of hub. Be sure lock ring is correctly seated.

Install cap to body assembly. Install three capscrews and tighten to 4-6 Nm (35-53 lb-in).

A — While Rotating Front Disc Brake Hub and Rotor, Tighten Wheel Retainer (Nut) to 68 Nm (50 Lb-Ft) to Seat Wheel Bearings. Back Nut Off 90 Degrees (1/4 Turn). Tighten to 1.8 Nm (16 Lb-In).

B — Tighten to 4-6 Nm (35-53 Lb-In)

I wish I had that picture before I demolished the autolockers. I didn't realize the ring part number 7 was there. I now have the rotors on and the auto lockers are replaced with the warn premiums.
I'll save this thread for future reference just in case.
Thanks
