CV axle shaft clicking on turns or shaking under acceleration? Replace worn CV joints with a complete axle assembly built for smooth, confident power transfer.
A CV axle shaft transfers drive torque while its joints accommodate suspension movement and, on driven steering axles, steering angles. Start a CV axle replacement by entering the exact year, make, model, trim, engine, transmission, and drive type. Then verify front or rear placement, driver or passenger side, quantity, and every application note. Similar-looking shafts can differ in length, joint design, splines, ABS provisions, and mounting details. Use the VIN when the selector presents more than one drivetrain or production option.
A CV axle shaft assembly may be sold as one side, a driver-and-passenger pair, or a front or rear set. Current A-Premium listings include a single front driver-side unit, paired front assemblies, and paired rear assemblies, so quantity and position need separate confirmation. Do not assume the left and right sides share dimensions or interchange.
Check whether the application is front-wheel drive, rear-wheel drive, all-wheel drive, or four-wheel drive, along with automatic or manual transmission notes. Some listed powersports axles also exclude lifted vehicles or particular suspension layouts. Treat each note as part of fitment, even when the year and model appear correct.
Clicking during turns, vibration under acceleration, or grease thrown around the joint area can justify inspection, but none of these observations alone proves the CV joint axle is defective. Check the boots for cuts, tears, punctures, missing or loose clamps, and visible grease slinging. On some applications, light surface grease may not indicate a torn boot; clean the area and inspect the boot and clamps before deciding on replacement.
Also inspect tires, suspension parts, axle fasteners, transmission or differential leaks, and the wheel hub bearing. Humming that changes with road speed may involve a bearing, while vibration can come from several rotating or supporting components. Confirm the source before buying a replacement CV axle assembly.
Use the vehicle selector, then read the product-page compatibility table and notes. Compare overall configuration, inner and outer joint ends, spline information when listed, ABS-related details, sealing surfaces, and included hardware with the removed axle. Chassis ranges, submodels, transmission type, and production dates can narrow fitment within the same model year.
If a vehicle has been lifted or modified, do not rely on stock fitment data without checking operating angles and the product restrictions. An altered ride height may place a CV axle outside the conditions covered by its listing. Contact support with the VIN and modification details when the product note does not resolve the question.
Support the vehicle safely and follow its service procedure for axle removal, seals, retaining hardware, and axle-nut tightening. Check the engine mount and transmission mounts if movement under load contributed to the complaint, but replace them only after inspection. After installation, confirm the axle is fully seated, boots are not twisted, clamps remain secure, and no fluid leaks or unusual noises appear during a controlled road check.
In shopping language, the terms often overlap. A complete axle assembly normally includes the shaft with inner and outer CV joints and boots, but confirm the listing photos and included components.
Usually not unless the product listing explicitly says so. The two sides can have different lengths, joint ends, splines, or support arrangements, so order by exact installation position.
Not automatically. Replace the axle that fails inspection unless wear, damage, or planned labor supports doing both. Inspect the opposite boots and joints before deciding.
No. Repeated turning clicks can support a CV-joint diagnosis, but wheel, suspension, steering, or fastener problems may produce similar sounds. Inspect and isolate the source first.
Enter the complete vehicle information and read the drive-type, transmission, position, and fitment notes. AWD and non-AWD shafts may differ even for the same year and model.
Should you replace CV axles in pairs? Not always. Unlike brakes, CV axles often fail independently due to isolated boot damage or asymmetric wear. Replace just one side if your vehicle has low mileage and the opposite boot is intact, saving ~50% on parts.

The CV axle is an essential part of your vehicle’s drivetrain. It transfers power from the engine to the wheels. This ensures smooth movement. CV axles can wear out over time.
Ever wonder how your car manages to deliver power to the wheels while simultaneously bouncing over potholes and navigating sharp turns? The secret lies in the CV axle.
