draining the front differential
What is the best way to drain the front differential? I have a 96 F250 with the dana 50 front end. My manual gives directions for the rear end, but nothing on the front. I just bought the truck so I don't know when it was last changed, I figured I 'd change all the fluids so I'd have a reference to go from. I can't see how you drain this front differential short of disassembling the whole thing. I would appreciated any advice thanks

you have to take off the cover and let the fluid drain out. losen all the bolts then take out the out just the bottom ones and pry the cover off, once the fluid is all out then take the rest of the bolts off and the cover, clean the gasket off of the cover and the housing, put on a new gasket and bolt it up, then refill it through the filler plug

the dana 50 is different than the dana 60 in the super duty. the dana 50 you do need to disasseble the axle and differential. i think you could drill a drain hole but this is risky since i don't know hoe close all the gears are to the housing. you need to pull the drive shaft and drivers side axle shaft. the passenger side shaft can be seperated at the slip joint. then you need to unbolt the differential from the housing. clean it out replace the seals and replace then refill. getting ready to do mine soon.
good luck

Thats what I was afraid of, I'm kind of short on time right now, would it do any good to suck the old fluid out and relpace it? I realize this isn't the best, but it might help until I get the time to do it right. Has anyone it done this way before? how did it work out?

I have sucked the oil out before, didn't get all of it but figured it was better than nothing. Heck when we change the motor oil in the PSD, you might be surprized how much oil we don't get out of them.
I like to drill hole and weld fine thread nut on them for a drain. They have worked out really good for me. I have done this on more than a few trucks I have had over the years. You can see what I have done on the 95' I have now in my gallery if you like.
Another really good way would be to drill a hole in the bottom of the banjo, then tap this out to 3/4" NPT and then get you the drain plug that you can use a 3/8" drive wrench. These will not hang down and fit flush.
