How much oil can a 8.8 diff hold?

I have a complete 98 mark 8 upper/lower arms and knuckle with half shaft that I want to swap into my bird. I forgot though when I pull out the half shafts oil will come spilling out. I filled it with 2.25 qts plus friction mod. How much is going to come spilling out when I pop off the shafts? How much will be left? I have .75 qts still handy but will it be enough with an another friction mod bottle to fill up the diff. Btw this is the expensive motorcraft full synthetic so if I could even collect it to reuse it that would be awesome.

When I filled my pumpkin it took about 1 3/4 bottle, so expect about half a quart to come out.

Well, you overfilled it to begin with.

When properly filled, and if the diff's level, you won't lose any when pulling the axles.

It was DirtyDog who told me how much to fill it and another member (Goofizzle) was actually the one who helped put it in the first start up. He didnt seem to think it was too odd. I know it fills it up a lot. Its a 3.73 TL set up, f150 spring,4 clutches, in a mark housing. Why is not ok to add so much aside from oil coming out of the sides.

When the fill plug is removed a very very small amount of fluid should ooze out, barely. If you pull the plug and it runs out it's overfilled. 1 3/4 is all mine have ever taken. As DLF stated when removing the axles the diff should loose very little or no fluid. Take a plastic bag and zip tie it over the holes, to prevent spilling it. Btw for what it's worth the one wheel method ftw. But since your doing mark lower arms anyway you'll have plenty of room to work with. You'll also need an alignment as soon as your done.

From the factory service manual:

Lubricant Capacities
Liters Pints
1.5 3.25 a

a All conventional axles use Premium Rear Axle Lubricant XY-80W90-QL or -KL meeting Ford specification WSP-M2C197-A, plus 118 ml (4 ounces) of Ford Friction Modifier F3TZ-19B546-MA or equivalent meeting Ford specification WSP-M2C196-A for Traction-Lok axles. Always fill rear axle to bottom of filler hole.

2.25 Qts = 4.5 pints, so if you really did put that much in, it's overfilled. However, the only way you could do that is if the car wasn't level, so I suspect that your measurement is off somehow.

When I fill a diff, I have the car level and run a tube into the fill hole with a catch pan underneath. Time to stop when it starts running out. Takes less than 2 qts to fill a completely dry diff.

And if the car is level when you pull the axles, you won't lose any fluid.

YOu may ask how I did it before doubting I did I used the filler hole on top, a long hose was stuck on it and a full bottle of fluid. We put a small hole in the bottom of the bottle with the tip cut to fit the hose end. We Blasted compressed air through the bottle and watched with amazement how big the bottle expanded under pressure. So we learned to back it off and get it filled in with steady air pressure. We jsut kept adding more and more to the bottle until we did 2.25 qts. Its in the diff for sure. I did it personally the second time that is the most recent time. I dont know if this was an exercise of some kind in being overly protective or not. OK whatever half qt. spills out just clean up and reinsert mark cv axles, yes?

I should pm DD as to why. I forgot if he explained why add that much. I'll be doing this in the dirt or the street LOL. Should I re add a bottle of friction mod?

Btw Anyone ever run mark arms without perches? Anyone have any feedback on that?

I have Mark arms without perches and it works perfectly. I have speed bumps in my neighborhood and have been on rough roads. They have never made any noise and work perfectly. All I did was put a Mark rear under the car with the original 'Bird coil springs and everything went together just fine. If you look under the car, of course the LCA's have a big pocket with those smaller springs, but no problems.

All else being equal, if you use the same parts (springs and isolators), then you'll lower the rear of the car about 3/8"-1/2".

Personally, I don't like the idea of the spring being able to move around. I used the aluminum perches from the earlier group buy at first, but I wasn't happy with those, so I made my own from UHMW.

Here's a link to a discussion on the subject:

IMHO unless your running air lift bags you'll be fine without them. Once everything's tight the springs aren't going to move around much.

As said though it will drop the car, so that may be a concern.

Well it already sits an inch higher in the back as it is. I don't know what the outcome will be but restassured you'll be seeing pics. Its pretty bad ass that I have come this far, nothing stock down to the rear wheels starting at the TC. The engine is the only stock part left.

Hey I pulled the axles and the oil all stayed in. LMWFAO! It holds 2.25 qts of oil and 1 bottle of oil friction mod. Yes the car was tipped foreward but the rear wheels where barely off the ground. So it wasn't that extreme. I left it as is and finsihed the mark8 swap.

Open diffs hold more because the case is virtually empty. 2.5 quarts is the normal fill level and what most manuals will say is the quanity. I know for sure anything les than 2 is not enough, there has to be some remaining in there if that fills it up. 2 quarts will make it where a screwdriver will barely show anything.
