Applications
Tech Note 1: Wheel Bearings
Some early 1977 1/2 ton GM 4x4s with Dana 44 front axles used QA40593 spindle that takes smaller inner wheel bearings. QU40313 spindle is made for QU50412 inner wheel bearing which has an inside diameter of 2.00". For the 1971-1977.5 1/2 ton spindle, see QA40593.
Tech Note 2: 1977.5-Earlier
Some early 1977 3/4 ton GM 4x4s with Dana 44 front axles may have had a wheel hub that used six 3/8" diameter bolts to secure the lockout hub or drive flange to the wheel hub. QU40313GM Spindle WILL NOT fit those early 1977 and prior 3/4 tons with the external mount hub! For the 1971-1977.5 3/4 ton spindle, see QU40323.
Tech Note 3: Before Installing
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.
