2001 4X4 Had a mechanic replace my transfer case this past winter and he said the front driveshaft CV joint bearings were worn out and it should be replaced. I'm getting an intermittent vibration coming from it now. Has anyone changed out one of theses on their own? Part #'s, Brand , Cost? Seems like one would need a band type clamp tool to secure rubber boot or has anyone done it differently? Is a flat nose plier needed to spread the lock ring on the splined end of the shaft? Anyone know the cost of replacing it at a Stealership so it gets done the right way with a quality part?
