What Viscosity Oil in Ranger hubs?

[pondigger2]

Just noticed I have a hub thats dry.....was good a couple days ago....could the heat have blown a seal?....it's on the brake axle....how tough is the seal to change and what grade of oil should I put in?....thanks

Some manufacturers say 75-90 gear oil. I beleive Ranger states 50W straight engine oil. Viscosities are close to the same actually. I put nothing but Lucas hub lube in mine. The day I switched to Lucas is the day my problems stopped. Pours like a super thick honey and is a lot thicker than the recommended oils.

ranger says 50w
i've swapped the orings in one of my ranger hubs; it was easy; the hard part was finding the orings; my dealer took a couple trys to get in the right ones; turns out my trailer is at a break in the run and the year/part numbers didn't work out like they should

if you search this site you'll find a link to a pdf that has all the details from the manufacturer
