    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?:biggrin_25523:

    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.
