Ranger trailer oil hub issue

Noticed one on the hubs on my trailer is cloudy. I would guess a leak can I relace it with grease hubs orhow hard is it to change oil hubs?

Change the oil, you have water in the hub. Wiredog

I have the same issue with one of my hubs, I changed oil and after two trips it was back to the chocolate milk looking oil. Obviously I have a small leak somewhere, any thoughts where it is coming from and how do I fix the leak?

Thanks,

First you have to make really sure you get the hub completely full of oil when you change it. Then if it gets cloudy again, you need to change the rear seal. Make sure you get the right seal. It takes a really good seal for oil hubs. Waymire.com 800-434-4824 They have the good stuff. You can also go to Bass Boat Central and go on the trailer forum, there are a couple of good posts near the top about oil hubs. Wiredog

If you need a seal call ranger

It takes very little moisture to turn the oil "cloudy". One could chase their tail looking for a "leak" when in fact it's just condensation. If you've let the trailer sit for a week and can visually see a defined line between oil and water, you have water intrusion. More than likely the inner seal. If it's just cloudy it's probably condensation. Mine get cloudy within a few trips of changing the oil, I have no leaks, no intrusion, level never changes.

This is the reason they went with solid covers over the hubs...so you can't see the oil, dumb, I know. They were getting so many warranty claims for "leaking" hubs when they weren't leaking, just condensation. The condensation won't hurt anything...so they say.

I went through all my bearings, seals, etc., last winter. I installed new seals since they were apart. Everything was tight and looked brand new...very good condition. That said, it's a 05 trailer, has many miles on it and the oil has been "cloudy" since it was a week old. I do change the oil in the hubs every winter and a few times mid summer when I've been in the garage bored...something to do.

They take 50 wt racing oil, easy to change. Jack up the trailer, put it on jack stands(level), remove the wheels. Remove the plug(allen head) that's on the hub. Rotate the hub down and drain....go find something else to do for a few hours....they take forever to drain, really!! Once drained fill back up with 50 wt racing oil. I use a turkey injector to refill...it's a small hole! The injector is the best solution I could come up with and I think it works great. Fill right to the full mark....don't over fill!! Use permatex or other thread sealant on the plug, snug down. Done. Repeat the process yearly.
