About CV Axle Assemblies

A CV axle assembly is a complete half-shaft with its joints and boots already fitted, ready to bolt in between the differential and the wheel hub. Owners buy one when a joint clicks, a boot tears and lets the grease out, or a hard hit bends the shaft, and some choose a heavier-duty version for rough use.

Listings name the machine and the position: front or rear, left, right or both, and in some cases rear middle. Standard OEM-replacement axles, heavy-duty axles, extreme-duty 8 Ball axles and long-travel X-Treme axles for the Polaris RZR are all listed. Machines seen here include the Polaris Ranger and RZR, Can-Am Defender, Yamaha Kodiak and Grizzly, Kawasaki Brute Force and Arctic Cat. Long-travel axles are made for machines with changed suspension, so use them only where the listing says they fit.

Brands in this category include EPI, All Balls, Moose Offroad, Demon Powersports and Moose Utility. If you only need a joint or a boot, see CV Joints, Boots & Parts. Other shaft listings are in Axles, and the gear cases they connect to are in Differential Parts. All are part of Transmission & Drivetrain. Pick your machine in the Ride Finder at the top of the page to see axles made for it.

FAQs on UTV and ATV CV axle assemblies

What does a complete CV axle assembly include?

It includes the shaft with the inner and outer CV joints and boots installed and packed with grease. Whether the nuts, clips or other hardware are included varies, so check the listing, and plan to reuse or replace the hub nut according to your service manual.

How do I choose the right axle for my UTV?

Match the make, model and years, then the position: front or rear and left or right. Pick your machine in the Ride Finder at the top of the page to filter the list, and compare the new axle with the old one for length and the spline ends.

Is a heavy-duty CV axle a direct replacement?

Most are made to fit the same position as the stock axle, but check the listing for your model. Some, such as long-travel axles, are made for machines with modified suspension and should be used only where the listing says they fit.

Should I replace both axles on one end at the same time?

It is not required, but a failed axle is a reason to inspect the other. If the boots are torn or the joint clicks, replace it too. Axles of the same age and use often wear at a similar rate.

What makes a CV axle fail?

The most common cause is a torn boot that lets grease out and dirt and water in. Hard landings, steep axle angles from a lift and abuse in mud or sand add to the wear. Check the boots regularly and repair tears early.
