    Default Rear axle case (Brakes)

    Just change the rear axle fluid and found my rear brake is leaking a lot if fluid. Anyone familiar with this issue? I cant say as Ive ever seen brakes like this in my life. Maybe I should stick to motorcycles. There is a bolt that threads into a hole on the rear axle (on both sides of the gear housing) and fluid is draining out at about a quart a minute. Not sure if screwing it all the way in will help or exasterbate the issue and Id like to avoid doing donuts if I hit the brakes. Im attaching a pic thats not the greatest but Im pointing at the area.Ling bolt on one end with what looks like a welded washer on the other end. GOD I hope nothing broke (bolt) because my Boss wants his backhoe by Friday and I dont think I can rebuild an entire rear end in 3 days. HELP!!!

    i'd be pming rickb or whodat... they are more familiar with later fords than i am... especially the industrials.

    I tried Messicks for a part by part list and diagrams. Seems they omitted some items from the list and photos. The part I tried to discribe was the "pull rod nut". it seems to be leaking from the housing that the bolt screws into.

    No joy with diagrams. I really didnt want to open that beast up but it looks like the only way. Exploratory surgery seems ineveitable.

    ugh. I'd deffinately PM rickb or whodat.

    I simply havn't been into those new / industrials and will be of minimal help except on common ford -ish stuff that might carry over fromt he older models.
