Always replace the cup and cone at the same time. The matching Bearing Cone for model 60 and 61 axles is QU50407. The matching Bearing for Dana 70U series axles is QU50408.

tech note

Installing bearing cups using makeshift methods such as a hammer and punch usually results in nicks in the bearing cup and a gouged housing. For a damage free installation, use QT1805 Bearing Cup Installer to seat this cup in your axle housing.
