Silverado Sierra Front CV Axle Shaft Pair 4WD

This is a matched pair (driver and passenger side) of complete front CV axle shaft assemblies for the GM K2XX/GMT900 full-size truck and SUV platform: 2007-2018 Chevrolet Silverado 1500, 2007-2020 Tahoe, 2007-2020 Suburban, 2007-2013 Avalanche, 2007-2020 GMC Sierra 1500, 2007-2020 Yukon/Yukon XL, and 2007-2020 Cadillac Escalade/Escalade ESV - 4WD/AWD models with 6-lug front hubs only. Cross-references to 66-1430, 661430, 15185911, 15868123, 20909191, and 22791460.

Each shaft comes fully assembled with both CV joints, boots, and grease already installed, plus the spindle/axle nut. Compressed length is 22.93in, the outboard end has 33 splines, and the inner spline is the 6-lug pattern (not the 30-spline pattern used on some earlier trucks) - confirm your truck uses the 6-lug front hub before ordering, since GM ran more than one spline count across these model years and engine combinations.

Replace the front axle shafts when you hear a clicking or popping noise turning corners (worn outer CV joint), feel a vibration under acceleration that tracks with road speed, or see grease slung around the inside of the front wheel from a torn boot. A torn boot lets water and dirt into the joint and will wear it out fast even if the axle feels fine today, so both sides are worth doing together if one boot has failed - they wear at roughly the same rate.

To install, remove the axle nut, separate the lower ball joint or strut as needed to swing the knuckle out, pull the old shaft from the hub and out of the differential/transfer case, then reverse the process with the new shaft. Torque the axle nut to spec and check front differential fluid level when done.
