    Front Wheel Hub Oil Type and Level

    Great forum. My question is this. I have a 1969 White Freight liner COE. I was looking at the front axle hub to check oil level. I notice the plug, pulled it and took a peek, no crap inside and looked more. Looks like some boob painted over the glass area around the plug. Now, how can I remove the pain to check level. What would be the type of oil? I'm thinking eather 85w-90w or 90w-140w? Is there a rule of thumb for the level? Untill I can figure a way to get the paint off to see how full. I need to add some untill the mech can check it out for a leak. Also need to track down the rear diffs oil and trans oil type 13spd Eaton Fullerton. Also, would you need to use additives in the rear diffs and trans?

    If you can tell what oil is already in there, that would be best, you don't want to mix stuff too much. 80W90 is fine, 50W synthetic works good too.

    I agree with above 80w90 and fill to about 1/4 inch below hole. Also you dont need to add additives to diff or box oils, but DO change them at least every 2 years at a max. p.s Dino / mineral oils are fine, no need to use syn but thats a personal choice. syn can be changed well never really (jet planes in the Australian Air Force use 100% syn and they never change the oil unless it gets containinated somehow.)

    I put some in and It flung it out. The mech that worked/knows this truck informed me that the front bearing where packed in grease.
