    Can anyone tell me how to service the transfer case on a 1977 F-150 Ranger XLT 4x4? Engine size is 351.

    Thanks.

    Normal maintenance is draining it and refilling it to the level of fill hole. If I recall correctly, you use 75 - 90 weight gear oil in those.

    Hi FTZ HAIC - Right, but I've been under the truck but can't see where that fill hole is...
