This axle is a well made part with no burring on the splines and is a exact replacement for the factory inner shaft on a Dana d30 front axle used on the Jeep Liberty. If you are replacing the half shaft CV axle you should go ahead and purchase the inner axle as wt the same time. Over time the inner axle seizes in the end of the right side half shaft and you will be without a needed part when you need it. the cir-clips are installed on the axle from the manufacturer.
