I have a 7745 and am trying to figure out how to check the fluid level for the front axle gear box as well as the planetary drives. I have found the plugs on the planetary drives but am not sure what position they are to be in when checking the fluid. I also found two plugs on the axle housing, but just wanted to confirm that the bigger one is for filling and the smaller one is the correct level plug. Also, on the transfer case for the 4wd, it only has a drain plug so am I correct in assuming that it is filled thru the transmission box? Thanks, juney
