- Ensure transfer case is in 2WD position. Clean flange surface of hub, thread holes, lock washer and axle shaft splines. Install inner cam with key in groove of spindle. Tap cam lightly to ensure that it touches lock washer.
- Hold inner cam and push stub axle of outer CV joint toward outside of wheel. Install Automatic Locking Hub Gauge J-33935) on axle shaft so it touches lock washer. Measure clearance between outer face of gauge and outer edge of snap ring groove. See Fig. 3. Adjust clearance with shims to range of 0-.004" (0-.10 mm).

- Remove gauge, making sure inner cam remains in place. Install drive clutch assembly. Check that assembly marked "L" is on left side and assembly marked "R" is on right side of vehicle. Lightly grease axle splines, inside of driven clutch, back and side grooves of drive clutch assembly.
- Align cut portion of hold-out ring with convex part of drive clutch assembly. Align clutch assembly with inner cam and engage teeth of drive clutch with inner cam teeth. Measure distance from outer face of spring retainer on drive clutch assembly to outer face of teeth on drive clutch assembly. Record distance as "Z".
- Using Snap Ring Installer (J-33934), install selected shims and install new snap ring. Ensure snap ring fits properly in groove of axle shaft. Measure distance from outer face of spring retainer to outer face of teeth on drive clutch assembly after installing snap ring and shims. Record distance as "W".
- If "Z" - "W" is larger than .0028" (.7 mm), shim selection is correct. Measure distance from face of hub flange to outer face of clutch assembly teeth. See Fig 1
. For a distance of 1.00-1.04" (25.4-26.3 mm), no spacer is used. For a distance of 1.04-1.07" (26.3-27.2 mm), use 1 mm spacer. For a distance of 1.07-1.11" (27.3-28.1 mm), use 2 mm spacer.
- Apply Loctite 515 to both sides of spacer and flange surface of driven clutch assembly. Install flange to driven clutch assembly. Tighten bolts. Apply Loctite 515 to flange surface of housing assembly. Install housing assembly with bolts and spring washers. Ensure housing assembly turns smoothly and tighten bolts.
