Installation hint: Please check the differential output retainer housing o-rings. Often they are cracked, crushed, or hardened from age. When reassembled, they will result in a oil leak. We also stock this Differential Output Shaft Retainer O-Ring. This is an inexpensive preventive fix to reduce chance of leakage in the differential output shaft area.
