My rear wheels kept being slung with grease but my CV shaft boots were in a sad, dry rotted state. I just finished putting on new boots and fresh grease yesterday and figured this would be resolved but it’s not for the left side. It’s apparently coming out of the hole in the end of the axle shaft into the hub of the wheel and then being slung out through tiny gaps between the wheel and the hub. My boots seem to be doing their jobs now though. Is this normal?
