On my wet hubs, the circle line is the minimum oil fill. There is a plug in the middle where you add the fluid. You cannot overfill it since any excess would run out that hole with the plug removed to fill it. Mine uses the 80/90 weight wheel bearing oil.

Filling that way, will put the oil level above the inner seal. as soon as the seal wears a little the oil will ruin a set of shoes. or lubricate your disk. and ruin a set of pads..

Wrong! Here is what the owner's manual says

As you can see, the circle line says minimum oil level.

For all the years I've been wrenching I've never seen one of those. Ya live, Ya learn.

AND....at now 10 years of age, those plastic viewing retainers of yours are likely soon to fail!! (Please do not ask me how I know that - mine failed (Spartan chassis with Eaton axles) halfway down the Columbia River Road and I had to make-up a temp bearing grease retainer from a plastic coffee can lid!!)

They are cheap to purchase - but are usually a special order item in most parts stores - 3 to 5 days wait! Put in a new set at your earliest convenience to minimize future difficulties!!

Well... there goes two more things into the survival kit. Mine are still quite clear at 15 years.

Now you made me worry.
I bought my 1972 conversion 10 years ago and wonder if those retainers are original?
But than I bough quality, not quantity.

Use gear oil rated GL-5. Make sure bottle says GL-5.

The "Type" of fluid is heavy weight gear oil.. Just how heavy I can not tell you (It is in ye old owner's manual) The other fun thing is the level. That is fun figuring out as well.

On the front axel on my coach there is sight glasses with fluid , what type of fluid does this require, how do I add it ?

What you are looking at is known as a "wet hub" the wheel bearings run in oil. your NAPA dealer has both types of oil for them, we run the synthetic type. the other is regular 80/90 gear oil.

Do not over fill. while the wheel is spinning the centrifugal force holds the oil at the out side of the bearing race, but while setting it will settle to the bottom of the hub and should never be above the circular ring which is the full line.
When over filled, the oil may seep out the inner seal, and ruin your brake shoes, or lubricate the brake disk. (not good) :)
