i do not recommend repairing the inner c/v boots, there is nothing wrong with thoes, its the actual joint that is failed, the rubber around the joint is no longer any good. most of the time, the clamp that comes with the repair kit does not clamp correctly on the repair boot, and when you compress the joint, you can hear air coming out of it indicating a leak, if this were my own car, i would replace the complete axle.
