Runout Check

1. Raise the vehicle on a hoist that supports the rear axle (twin post hoist).
2. Remove the driveshaft assembly.
3. Inspect the rear axle universal joint flange for damage.





4. Position Companion Flange Runout Gauge T92L-4851-B on rear axle universal joint flange.





5. Install Clamp Plate T92L-4851-C on runout gauge.





6. Align holes in clamp plate with holes in rear axle universal joint flange and install bolts. Snug bolts evenly.





7. Using Dial Indicator/Magnetic Base D78P-4201-B or equivalent, turn Companion Flange Runout Gauge T92L-4851-B as shown to locate and mark high spot on rear axle universal joint flange. if flange runout exceeds 0.254 mm (0.010 inch), remove rear axle universal joint flange, re-index 180° on pinion and re-install. Check runout again. If flange runout is still more than 0.254 mm (0.010 inch), replace rear axle universal joint flange.

CAUTION: This operation disturbs the pinion bearing preload. Pinion bearing preload must be reset if the pinion nut has been loosened or removed for flange re-indexing or replacement.

8. If excessive runout is still evident after replacement of the rear axle universal joint flange, replace the differential ring gear and pinion. Repeat the above checks until runout is within specifications. Install the driveshaft assembly. Tighten bolts to 95-130 Nm (70-95 ft. lbs.).
