While changing out a ball joint, I accidentally punched through the rivet, stabbing a hole in my cv boot with the drill bit. Now my cv boot leaks grease. I have tried patching it with a innertube patch. The hole is right in the crease so it is really hard to get the patch to seal properly. I am trying to get it sealed up. I guess I am curious what is the prognosis. If the boot leaks, what will happen? Will the cv joint actually fail? How hard is it to replace the boot? Are there any replacement options where I don't have to take apart the hub?
