    So a couple days ago I pulled the cover off the front diff (dana 44) to check it out (vehicle is new to me). I filled it back up, and since my driveway tilts there was a little extra in there, but not much. This morning I notice that I've got a puddle of clean gear oil sitting next to the driver's side tire. It's leaked out the end of the axle. Sounds like I need some new seals? I'm a newbie to axle work, what am I going to need? I just did the front brakes and put new hubs on this, do I have to take most of that apart again? Any tips? I just read an old post of Grim's with some tips for taking the carrier out to replace the inner axle seals, is that what I'm looking at doing?

    Given that the gear oil is leaking out the end of the axle, how much driving around with the hubs locked can I do before the bearings or something else is trashed?

    thanks!
    Kevin

    That's basically what you have to do. Pull the axles and carrier out replace seals reinstall everything else. Or until your ready to do other mods(maybe ball joints, u-joints, locker lower gears, etc...) something to help justify the effort, to the axle, just park opposite and keep the driver side higher than the passenger side. I'd say with the front turning the oil level would be lower than if not turning and you probably will not loose as much as it just sitting.

    So having gear oil dribbling through the axle isn't going to break down the bearing grease? or cause other problems?

    It shouldn't get as far as to contaminate the bearing grease but if it did it wouldn't break the grease down, water is grease's worst ememy.

    you are gonna need to pull the hub apart then take the rotor off pull the backing plate off. then you are gonna need to pull off the housing behind the backing plate. pull the backing plate off the diff and pull the pin and the c clip off the axle slide the axle out and then pull the axle bearing and grease seal replace both be carefull with the seal you dont wanbt to damage it. put the bearing in and the seal lube up your axle with axle grease slide it in and put the c clip and pin back in and put everything back together and but while you are in there replace the hubs bearing and races and rear grease seal and be sure to grease the spindle and pack all the bearing you replace with bearing grease something water resistant is the best. but put everything back on and you should be good it sounds like a bigger job than it is its pretty easy. /forums/images/graemlins/usaflag.gif /forums/images/graemlins/truck.gif /forums/images/graemlins/thumb.gif

    There arent c clips in the front of a dana 44. The spindles and hubs keep them in. The only thing is that if the seals bad, the axle shaft might be bad too.

    I 2nd that and agree with you. A front axle is a full-floating design. No C-clips.
