Shop now for Differential Bearings and Pinion Bearings specific to 1946-1959 GM H072 and 1956-1959 GM H052 Full Floating Rear Axles. In stock. Quick shipping.
The GM H052 and H072 series of axles all used the same differential bearings from 1946-1972. The original bearings supplied by GM's NDH Bearing Division had unusual, now obsolete, barrel-type rollers which are currently replaced by a taper bearing cup and cone. Although the taper bearing set will directly replace the original barrel bearing sets, individual components of the two types are NOT interchangeable, You can not use a taper cup with a barrel bearing or a taper bearing with a barrel cup. The differential bearing cup and cones MUST be replaced as a set. For the pinion, different, non-interchangeable bearings were used depending upon the year.
