loose hub leaking oil

i have a 2001 f350 and the front passenger side hub is loose and it wiggles a lot. also the axle on the passenger side is leaking oil right were the safte goes into the axle body. is the leaking caused by the loose hub. i dont know much about axles just motors. so if anyone can help it would be very helpful. thanks

I noticed today that mine is doing the same thing on the passeneger side. Pretty sure same spot as yours. Don't know much about it either but I'm guessing there is an oil seal thats going.

Hopefully someone chimes in on how to change it.

sounds to me that you might have one of a few different problems or a combination. the hub problem could be from a bad hub or a wheel bearing that is shot and the leaking fluid sounds like you have a bad inner axle seal. the best thing to do is to start tearing your front end down and see what is going on.

well one way to test a wheel bearing is to jack up the side and pull out on the bottom of the tire and push in on the top and vice versa. if you get some movement then its probably a bearing. i dont know of a way to test the seal besides pulling it out. when you go to install a new seal you will need to make a driver out of a 1 1/2 inch galvanized nipple and a flange to hammer it on. or you could buy one from ford

If its leaking out the axle tube then you have leaking in axle seals. You need to remove both axle shafts and the carrier to replace those seals. Its a fairly big job. You might as well do front axle u-joints, all 4 ball joints and sounds like you need a wheel bearing too.

alright so i got some good news i found out that none or very little oil has leaked out of the axle. i finally got a chance to pull off the cover and it leaked some of the oil out so i figured if it did leak some oil it was very little but it seemed like a lot more so i think now it is just the wheel hub or bearing or something of that nature

Well I took a quick look today & mine doesn't appear to leaking now either. I haven't checked the oil level in the diff. & I haven't used the 4x4 since I noticed the leak. Which is probably why its not leaking now. I expect once I use the 4x4 it will start leaking again. I need to get under the truck & take a better look cause leaks usually don't fix themselves.
