Front driveshaft for 1999-2007 Silverado/Sierra 1500, Tahoe, Yukon, Suburban 1500 and Avalanche 4WD. Replaces GM 15087450, 15764125 and 938-221.
This is a complete front driveshaft assembly for the GMT800 half-ton trucks and SUVs. It replaces GM 15087450, 15090192, 15182095, 15711973 and 15764125, and cross-references to Dorman 938-221.
Listed fitment, 4WD only: 1999-2006 Chevrolet Silverado 1500 and GMC Sierra 1500, 2007 Silverado 1500 Classic and Sierra 1500 Classic, 2000-2006 Tahoe, Yukon, Suburban 1500 and Yukon XL 1500, and 2002-2006 Avalanche 1500. 2500 HD models use a different shaft.
The shaft is steel, straightened and dynamically balanced, with the slip yoke greased. On these trucks the front shaft is known for a clunk or knock when the front axle engages, a clicking at low speed in 4WD, and a slip spline that dries out and binds. Replacing the complete shaft fixes the joints and the spline at the same time.
Install: shift to 2WD, mark the flanges, remove the bolts at the front differential and transfer case, and pull the shaft. Install the new one in the same orientation, torque to factory spec, and road test in 2WD and 4HI.
