Shop now for Axle Shafts and Axle Universal Joints specific to 1969-1972 Chevy and GMC 4x4 trucks equipped with Dana 44 Open Knuckle Front Axles. Great selection. In stock. Quick shipping.
GM used at least three different axle shaft configurations for 1969-1972 Dana 44 front axles. 1969 Blazer inner axle shafts are 1" shorter than 1970-1972 axles. The outer axle shaft for 1969-1970 drum brake axles are 1/10" shorter than those used on 1971-1972 disc brake axles. In mid-year 1972, the axle u-joint size was increased from 1310WJ series (1-1/16" cups) to 1350WJ series (1-3/16" cups) although the lengths remained the same. Also during the 1972 model year, the spindle to axle seal was first changed from a 2" ID conventional seal to a 2" ID rubber V-Seal. Late in the year, the outer axle shaft changed again when the spindle seal ID was increased from 2" to 2-1/4".
General Motors used an small Spicer 1310WJ series axle universal joint with tiny 1-1/16" diameter u-joint cups for the 1969 to 1972.5 Dana 44 open knuckle front axles. The physical dimensions of this series of axle joint means is marginal for full size truck applications which is why it was replaced by Spicer 1350WJ series medium size axle u-joints with 1-3/16" cups during the 1972 model year. Always verify your axle u-joint cup diameter before ordering replacement u-joints.
