Automotive Replacement Constant Velocity Half-Shaft Assemblies

A CV half-shaft assembly transfers torque from the transaxle or differential to the wheel while allowing for steering and suspension movement; replace it if you have torn CV boots, clicking during turns, vibration under acceleration, or grease leaking from the joint

Match the assembly to your vehicle year, make, model, front/rear and drive type (FWD, RWD, AWD), and side (left/right); cross-reference OEM part numbers or vehicle fitment charts from the supplier to ensure correct spline count, overall length, and joint type

A complete assembled half-shaft typically saves installation time and ensures proper balance and joint preload, while replacing only the CV joint or boot can be cheaper but requires more labor, specialized tools, and correct torque/balance procedures

Compare build materials (forged vs. cast), joint type (ball vs. tripod), boot material (rubber vs. thermoplastic), included hardware and clamps, and warranty length; reputable aftermarket brands often provide matched assemblies and corrosion-resistant finishes

Aftermarket CV half-shaft assemblies generally fall across a broad range; budget options can start under $50 while higher-quality or vehicle-specific assemblies may be several hundred dollars, with typical averages for many passenger vehicles around the mid-hundreds

A competent DIYer can install one with vehicle-specific service instructions; common tools include a jack and stands, axle nut socket, breaker bar, torque wrench, pry bar or slide-hammer for axle removal, and possibly a ball joint separator or hub puller

Inspect boots regularly for cracks or grease leaks, promptly replace torn boots to prevent joint contamination, avoid aggressive hard launches and curb impacts, and address wheel bearing or suspension issues that can add stress to the shaft
