I'm trying to remove a broken bleeder valve. I need to remove the whole drum brake housing to get to it with a screw extractor. The vehicle is a P3500 Value Van. It's a dually 1 Ton Box Van (food truck). To remove the drum (to get to the back plate) I need to remove the axle their is some oil that comes out when I do this. How do i top this oil back up (where do I fill it at) and what kind of oil is it?
I don't think you need to pull the axle to replace the brake wheel cylinder (if that is what you are doing). Maybe so, but, usually can get to the wheel cylinder bolts from behind and there is normally clearance. If you do pull the axle and oil leaks out, the refill is the plug on the rear differential. When done, just top it off until it runs out.
You need gear oil, the type you need depends on the year of your truck. It also may or may not need friction modifier. I would guess there would be some type of fill plug near the top of the pumpkin.
That seems odd that you'd have to pull an entire axle to remove the brake assembly. Maybe post a picture so we can see what you're working with, but I would certainly think you could do the job without removing the axle.
First of all... save yourself some time and just throw away the old wheel cylinder, they are $10-15 for a reman. Secondly, the way to prevent oil from coming out is to jack up the side of the axle you are working on as high as you can while it still being safe - Now the angle of the axle will cause the oil to stay on the opposite side and you shouldn't have a mess to worry about. If you elect to replace the cylinder (again, highly recommended) you shouldn't have to remove the axle, just the two bolts fastening the cylinder.
Why do they do these things?! Full floater, axle then hub has come off to perform brake maintenance, what a cluster **** 2nd gen Rams with D60s in the front were similarly stupid - rotor replacement required hub bearing removal as studs were pressed through back of rotor then INTO hub.

Those type of axles are normally used on heavy duty vehicles, like wreckers, and such, which constantly carry heavy weight. The bearing tend to wear faster as well, compared to a car or say F150. Its like that so when you replace the brakes, you can service the bearings as well, a little faster than doing on a normal axle and everything just about comes out at once. Older technology, but it works.

Totally understand this for a dually as it is the normal setup, but for a single wheel floater, unnecessary.
Has been accomplished by other mfg's without having to pull axle and hubs.
