Wheel grease escaping?

One wheel (of four) on our Fleetwood Prowler is showing some signs of escaping grease. I opened the grease cap, though and there is obviously lots of grease in there still. The cap was tight. I had to pry it off with a hammer and screwdriver. Is there something else going on here?

    Need to check the rear area of the drum, if any sign of grease back there the grease seal is most likely leaking and could have gotten on the brake shoes or magnet.

    One thing you may want to check if the bearing on that wheel is heating up. After driving for 15-20 mins compare the warmth of that hub to the rest of them.
    Could be the indication of a problem bearing.

    It may fit tight but not have an even seal all the way around. You can clean it up good and put a tiny bead of silicone sealer around the edge that meets the hub. Some mechanics do that every time.
    As long as it's not streaming from the backing plate there's no cause for concern.

    I took a photo but can't see how to post it. (I know there used to be photos here). There are dark gray streaks coming from the hub out from under the hub cap. When I remove the hub cap I can see the grease cap is tight.

    Where are you seeing it? From around the grease cap?
    If so then no biggie. Either ignore it or pick up a new hub-cap.
