Sierra 1500 4WD V8-6.0L (2007)
7. Using the J 34672, measure the distance from the machined surface of the differential carrier housing to the outer surface of the front drive axle
clutch shaft.
8. Subtract the measurement obtained in step 6 from the measurement obtained in step 7.
This measurement is the distance between the inner axle shaft and the clutch shaft before subtracting the J 34673.
9. Using a micrometer, measure the thickness of the J 34673.
10. Subtract the thickness of the J 34673, measured in step 9, from the measurement determined in step 8.
This is the shim thickness for the front axle without having any axle shaft endplay.
11. The correct shim size will be one size smaller than the figure obtained in the previous step.
Note the following examples:
*
If the figure obtained in step 8 was 3.53 mm (0.139 in), use a 3.30 mm (0.130 in) shim.
*
If the figure obtained in step 8 was 3.30 mm (0.130 in), use a 3.05 mm (0.120 in) shim.
Alternate Adjustment Method
Important: Use this method only if the proper tools for calculating the shim size are unavailable.
1. Install the original shim to the shaft.
Use the chassis grease in order to hold the shim in place.
2. Install the inner axle housing assembly to the differential carrier case.
Do not use sealer at this time.
Notice: Refer to Fastener Notice.
3. Install the bolts.
Tighten the bolts to 40 N.m (30 lb ft).
4. Measure the shaft end play using the following procedure:
1. Install the J 8001 or the equivalent on the axle tube end.
The plunger of the indicator must be at a right angle to the axle flange.
