That information is posted within this forum if you search.

SUPERCUB: You should use 75W90 Synthetic gear oil. Mobil 1 brand is readily available in a 1 qt bottle for ~ $10.00 / qt.

When refilling, pull the rubber plug in center of hub (the screw in cap is for draining) and fill to the bottom of the plug hole (excess will run out). Replace plug and drive unit to insure distribution, then recheck level. Don't overfill or you WILL get a mess to clean up. ED

So how come the WH service center says to fill to that painted on line (circle) as a fill line and not to the oil comes out?? Which is correct?

YosemitebobR: Thanks for your question. To be certain my recommendation was correct, I now have my spare front hub seal in hand. On the flat flange portion (with the four mounting holes) it shows the part number to be CR 1608 USA. This flange also provides the info to torque to 12-16 lb-ft. There is a production date stamp and the U.S Pat. #. My spare was the original equipment on my chassis, so I know WCC installed it.

As you pointed out, there IS a white line running around the clear portion (sight glass) of this part. On mine, the white line goes around approx. 2/3 of the circumfrence of the sight glass and the remaing 1/3 has upper case letters "MINIMUM OIL LEVEL". The white line is approx. 1/2 inch outside (below) the OD of the rubber plug hole in the center. Therefore, I stand by my original recommendation to fill with oil to the level of the plug hole. Any oil level below the white line would be an indication that more oil is needed. The problem with filling above plug hole bottom is that the excess oil can seep out around the push in rubber plug then be scattered over the rim and tire by centrifical force. It is really difficult to remove from these surfaces.

Hope this information is helpful. ED

Ed, thank you for an excellent response to my question. I no longer have any doubts as to where I should be in respect to level. Mine doesn't have quite all the lettering you say yours has, but then again I don't quite see that well looking upside down. Something is there, but the line is absolutely there. I have always made sure my oil was to this line and never below it. However, from your explanation I should be above this line as I will now be. Again, thanks. Four years old and still learning (coach that is)me on the other hand, well.....

I toped mine off via what your calling the "drain", and why not? Since this is a threaded plug it seems a much better choice than to pry the center rubber plug out. Zero chanch of damaging the seal when using the drain.

I would say the main reason for NOT using the drain plug is that you can overfill the hub.

Any excess oil will sure shine up your tires when the oil heats up .

[YosemiteBobR]

I think now that I have read some of these posts that is the exact reason my WH service center told me to use the white line and never let it get below it. As I had told him some time ago that I did just that, remove the drain to fill the hub. By doing that you cannot be sure as to the proper fill. Danger in overfilling is the shinny tires and possibly making you think you have a bad wheel seal.

Joe: there is nothing "wrong" with your method, but the plug is designed to be pulled out, and is easily pushed back in. With the plug out, any excess oil will simply run down and can be easily wiped off. If you inadvertantly overfill due to adding through the screw cap you won't get an overflow to wipe off. Just be careful not to overfill.

Please don't call me to help clean you tires ED

I agree either way works but anyone with the ability to check and add oil is surly able to top off the hub to the correct level. Why would anyone overfill it?
