Clearance between Differential Case Bore (Differential Case
Cover Bore) and Differential Side Gear Boss
1. Measure the bore I.D. of the differential case and differential
case cover.
2. Measure the differential side gear boss O.D. and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace them.
