Pinion Gear: Testing and Inspection
Axle universal joint flange runout should be checked when all other checks have failed to show the cause of vibration.
Another cause of excessive companion flange runout is improper installation of the axle drive pinion seal. Check to see if the spring on the seal lip has
been dislodged before replacing the differential ring gear and pinion.
