Re: CV boot...how much grease?
They should have roughly about two ounces of grease in each joint. Everything should be well covered, but there has to be some air space too.
Short of trying to figure out exactly what that is, you can make a rough guess at how much you're getting in there. It's about 1/2 of a measuring cup, or two of the disposable quarter cup drink mix scoops.
I wouldn't recommend trying to measure it, just use that for an approximation. The joint will end up about 25-30 percent full, but it'll seem like more.
Definately don't go overboard with filling it, as there needs to be air space in there for the expansion and contraction of the inner joint and both boots
