6. Align the holes on the clamp plate with the holes in the rear axle U joint and install the bolts. Snug the bolts evenly.
7. Use Dial Indicator/Magnetic Base to turn the Companion Flange Runout Gauge as shown to locate and mark the high spot on the rear axle U-joint
flange.
If the flange runout exceeds 0.25 mm (0.010 inch), remove the rear axle U-joint flange, reindex one half turn on the pinion, and reinstall. Check
the runout again. If necessary, rotate the rear axle U-joint flange until an acceptable runout is obtained. If the flange runout is still more than 0.25
mm (0.010 inch), replace the rear axle U-joint flange.
8. If excessive runout is still evident after replacement of the rear axle universal joint flange, replace the ring end pinion. Repeat the above checks
until the runout is within specifications. Install the driveshaft.
