back hub showing milky oil
 
my back starboard side hub on trailer is showing milky oil, I changed the oil after my long trip when I got the boat. this hub was a little low so I changed the oil and also checked the backlash on bearings. put it all back together per instructions but showing some milky oil. this is my frst time with this style hubs, I am asuuming it is the back seal, I have never had disk brakes and it does not look easy to take out the back seal when taking off hub. The disk brakes are attached to it

any advice on this one

Here is a great article about fixing the rear seal. Did mine a few years ago. Very easy to do.

Check your bearing cap, if you have the original plastic ones they sometimes crack allowing water to get in there. They have an o-ring on them too, check that also.

The inner seal is no different to change out than on the front of a car.
Remove caliper, remove rotor, pry old seal out with a seal puller or small pry bar, carefully install new seal.

Thanks for the link, mine looks exacly like that in the pictures. Do you need to remove the brake pads or will the complete assembly come off the rotor.

When I drained mine I just used the plug on the metal cap. seemed to work ok

The brake pads will stay in the caliper. Make sure to support your caliber when you remove the bolts - dont let it hang by the rubber brake line.

Thanks, I think I am going to try it on my own. I have done my other hubs with the grease style but I have never done brakes. Guess I am scared of them for some reason. If the caliper comes off with out touching brakes I think I have it figured out.

thanks for info

One thing the article doesnt mention... When you clean up those caliber bolts, you can put some anti-sieze on the bolt shank to keep the caliber moving and adjusting under load and heat. This will help prevent the corrosion with the constant exposure to water and heat.

I have it tore apart, the only seal I could locate locally has a steel outside not rubber coated.

Any thoughts on using this seal vs the rubber coated that was in there.

autoparts store said it would work

The old seal came out very easy, almost to easy

Here are pics of the seal I replaced my leaking one with. I picked up a spare when I replaced it. Worked just fine.

Images wont upload for some reason. The metal seal with rugger gasket will work fine.
