Applications

Tech Note 1: 1971 & 1972 Axles
All 1971 and most 1972 1/2 ton GM Dana 44 front axles use a 2" outside diameter slinger on the outer axle shaft. QU40071 large spindle V-Seal that comes with QU40593 Spindle is made for the 2-1/4" diameter slinger found on late 1972 and newer outer axle shafts. To use QU40593 spindle on your 1971-1972 axle with a 2" outside diameter outer axle shaft slinger, you MUST replace the large V-Seal with QU40043 one-piece spindle seal and replace the plastic thrust washer with QU40232 bronze thrust washer.

Tech Note 2: Verify 1977 Inner Wheel Bearing Cup Size
QU40593 Spindles were used from 1971 to early 1977 on GM 1/2 ton Dana 44 front axles. The matching inner wheel bearing has an inside diameter of 1-25/32". Most 1977, 1/2 ton GM 4x4s with Dana 44 front axles used QU40313 spindles and use 2" inside diameter inner wheel bearings. If you have a 1977 axle, verify the inner wheel bearing size!

Tech Note 3: Grease
Before installing your new spindle, lube the bearing, seals, and thrust washer with QU90018 Pyroplex® grease. Also, apply some Anti-Seize Compound to the mating surfaces between the spindle and steering knuckle.
