Reduction gear oil change

[Sal gambe]

Hi I went to change my front differential case and final reduction gear case oil first it tells you drain your axle differential oil and Fill to lower end mark on dip stick
Then The manual said remove each drain plug from each reduction gear case after the oil has drained and filled reinstall each of the filler plugs which tells me they meant two Filler plugs which I do not have
My question is if I change the oil in the axle differential case and fill it up and then drain my reduction year case on both sides does that pull out the new oil in my front axle differential case

That manual is a bit confusing;
I would recommend carefully and completely examining your front final drives
looking for a level plug.
Depending on how the front axle casting is built would determine if the oil would
make it to the final drives when filled to the low mark on the dipstick.
Your manual should give a volume of required lube for the axle.

If you are really unsure...
pull all the plugs and drain. Replace the axle housing plug only. by refilling it should also fill the final drives as well. once you see the final drives starting to drain new fluid replace their plugs. Fill to level required.
If nothing comes out of the final drives that would indicate they need to be filled separately. (not common)
Check for leaks and recheck the fluid level after a day or two of use.

Thanks rebeldad that makes sense I was thinking of the same thing because if it’s filled by the front axle it should start coming through the reduction housing that would make the most sense and be the safest knowing that it’s filling up the reduction housing also

manuals are not always the best information. lot of them are written by people who know nothing about what they write. I know for a fact.... Have a brother-in-law who writes these.
They are better than nothing but always use common sense.
