A-Premium Front CV Axle Assembly for GM 4x4 — Driver or Passenger Side, 22.91in 33-Spline, Axle Nut Included

This A-Premium front CV axle shaft assembly replaces the driver- or passenger-side axle on compatible 4x4 GM trucks and SUVs, restoring reliable front-wheel drive power and steering response.

If your vehicle exhibits vibration, clicking during turns, or grease on the inner wheel area, a worn or damaged constant velocity (CV) axle may be the cause. This replacement axle is built as a direct-fit part for many late-model Chevrolet, GMC and Cadillac 4x4 platforms, designed to match OE dimensions and mounting points so installation is straightforward for experienced mechanics or well-equipped DIYers.

Which vehicles will this CV axle fit?

This assembly is engineered to fit a wide range of GM 4x4 models across multiple model years. It covers Escalade, Avalanche, Silverado, Tahoe, Suburban, Sierra, Yukon and related extended-length variants where the original axle has the same spline count, length and nut thread. Always compare your original part number and measurements before purchase.

• Cadillac Escalade 2007–2020 4x4, Escalade ESV/EXT where applicable
• Chevrolet Avalanche 2007–2013, Silverado 1500 2007–2020, Tahoe 2007–2020, Suburban 2007–2020
• GMC Sierra 1500 2007–2020, Sierra 1500 Limited 2019, Yukon and Yukon XL 2007–2020
• Reference numbers include 15185911, 15868123, 20909191, 22791460 and factory IDs like 661430

How does this axle match my original equipment?

The assembly is specified to mirror key OE characteristics so it installs and functions like the factory part. Critical dimensions—compressed length and spline counts—are matched, and the unit comes prepped with the axle nut included for convenience. Note that this version does not include an ABS tone ring; vehicles requiring an ABS ring should verify compatibility before ordering.

• Compressed length: 22.91 inches to align with factory geometry
• Output spline count: 33 splines for secure coupling to the hub
• Input shaft bolting: 6-bolt flange for direct fitment
• Spindle nut thread: M24 x 2.0; axle nut supplied

What should I expect during installation and performance?

Installation follows standard front-axle replacement procedures: raise and support the vehicle, remove the wheel and hub components, unbolt the old axle and slide the new unit into place. Because the axle is a full assembly with grease and boots preinstalled, it reduces preparation time. After installation you should notice smoother power transfer to the front wheels and elimination of turn-related clicking if the old CV joint was the problem.

• Full assembly with pre-greased joints and protective CV boots
• Axle nut included to simplify reassembly and torqueing
• No ABS ring—verify ABS tone wheel requirements on your vehicle
• Designed to meet torque and alignment tolerances of the original part

Are there any fitment or maintenance tips I should know?

Confirm fitment by comparing spline count, compressed length and spindle nut thread to the removed axle or factory part listing. If your vehicle uses an ABS tone ring or sensors that mount to the axle, verify whether they attach elsewhere on your hub assembly. Routine inspection of CV boots after installation helps prolong service life.

• Verify 33 splines, 22.91-inch compressed length and M24 x 2.0 nut thread
• Inspect hub and suspension components for wear while replacing the axle
• Torque the axle nut to vehicle manufacturer spec to avoid premature wear
• Check boots and clamps periodically for tears or leaks

Who is this for: Mechanics, independent repair shops and hands-on owners who need a cost-effective, direct-replacement front CV axle for late-model GM full-size trucks and SUVs. It’s aimed at vehicles that match the listed fitments and specifications and for users who want a ready-to-install axle with the necessary nut included. If your vehicle requires an ABS tone ring integrated into the axle, choose a part explicitly listing that feature.
