The tube may be bent in relation to the axle. Everything should be parallel and concentric for the seals to work properly. You say it is seeping from the bottom right? The bottom of what? The flange or the axle itself. If it is leaking at the seal to axle mating surface on the lower seal lip, then your housing tube is bent slightly down, or your flange end is bent slightly down. The seal is getting more contact from the axle at the top, and not enough at the bottom. The opposite applies if the tube or flange is bent upwards. The housing can be straightened, but you need to strip the axle completely, and remove it. If you try to do it on the vehicle, you may blow up due to the proximity of the fuel tank. I'd recommend taking it to shop, though you can do it yourself with a rosebud, small porta-power, straightedge, a fab table, and a good jig set up. You'll need a few measuring implements, as well as the ability to use them. Or, just get the housing replaced. Just my 2 cents, after taxes, not worth a thing. Dann
