    Anyone changed there front diff fluid in the front? How much fluid and is there a drain plug or do I have to take a cover off? Also, can I just refill it with the oil bottles or do I need special funnels or something to refill it? Thanks!

    if yes its easy to do.

    pull drain plug. let drain till you happy. put plug back in. and tighten it.

    best if you get a cheep suction/blow gun to refill.

    use around 2.5 qt of 75-90 synthetic and refill till just before flow out of fill hole.

    install fill plug and have a nice day.


    reason i know is 2x i fix cars/trucks all day

    and i just did one last weekend.


    if you have the aam rear axle its just as easy. thay have a drain plug under the center of the diff. and a fill plug at the cover. same oil and just over 4 qt.
