I'll try changing my diff fluid myself next time I change my tranny fluid. Looks like I'll need some new tools to do it.
So, will the fill nut require a 17mm socket? Confirming if this is the right size.

I can't remember the size of the nut, but you better wear clothes you don't want anymore. A large plastic ground cover will be necessary also. If you have a pump to get the fluid into the differential that would help A LOT. Gravity feed from above through a little tube doesn't work very well.
There is a hex nut for the drain, right? I can drain that into my oil pan, shouldn't be that big a deal.
Can't I gravity-feed through a funnel + 1/2-inch 3-foot section of clear plastic tubing?
The hard part seems to be getting the fill nut off...
Already got clothes I "don't want" anymore... got them from changing my tranny pan gasket. :)
Yes, I meant that. :)
Ok, thanks for the advice.
Thanks also for the Tri-Flow Idle Air Control Valve advice. Finally got some Tri-Flow from a motorcycle shop, sprayed four quick squirts into the throttle body IAC intake, and now the car doesn't seem to stall anymore on the hills. There was a hill in front of my parents' house that the car would always stall on... no more stalling on that hill. :)
I use an oil-pump to fill the diff ('96 Manual). It's a messy job as you either keep withdrawing the tube to check how full it is, which drops oil on the ground,..or you keep pumping till it over-flows, which drops oil on the ground.
My pump has a tube for inlet and outlet.
A more intelligent way might be to jack the front up to give you some more fill-space, and then pump the exact amount as per the handbook into the diff.

You have a manual... don't you need a very viscous fluid for the manual diffs? The automatics call for Dexron II/III...
That's true. The manual diff uses SAE 70w/90 . Why that is I can only surmise the diff is more likely to suffer harsh power application,.like too fast clutch take-up, so they use an increased film-strength oil to stop metal to metal contact.

I went to Pep Boys and bought a 17mm socket for $2.50, then went under the car to see if it was the right size. Yes, it's the right size, but now I've got a problem - there's a crossbar in the way so I can't use my socket wrench. Maybe if the 17mm socket were half as long as it is... they don't make "short sockets" do they?
Good thing I checked... I was about to buy a whole set of 1/2" sockets for $20 from Wal-Mart. They wouldn't be necessary, at least not yet, at my skill level...
Guess I should buy a regular 17mm wrench, but maybe a foot long, for extra torque? I googled "combination wrench", and these look just like the (English) wrenches I have; I have an 11/16-inch which is really close to 17mm (17.526 mm, my conversion program says), but it's only about 7 inches long. I'm not sure how I would extend the length of my combination wrench... stick a smaller sized wrench in the "box"? Doesn't seem very secure...

You're on the right track. Put the box end on the plug, take an additional combo wrench and put the box end on the side of the open end that is in the direction you want to turn. Kind of like a puzzle, but if you position it right it will become (almost) one wrench that's twice as long. They do make a handle of sorts that's designed to extend an end wrench but I've never used one as the above worked for me any time I needed additional torque. HTH, davidj92

Tried that... finally got the "combination" to work. Unfortunately, when under the car, I still was not able to get enough force on the combination wrenches to turn the nut (very awkward to try it under the car, with limited room!)
Tried using an extension/socket wrench, too, to see if I could work
*over* the frame support. No luck - there's somthing just above the frame support, so that the extensions target just above the diff fill nut.Even tried tapping the wrench with a hammer... this just caused me to strip my nut slightly.
Neighbor suggested spraying with WD-40, then hammer again, but I'm a bit afraid to try this. (If the nut is loosened with WD-40, might it come loose more easily while driving???)
Ah well... perhaps this one *is* best left to the dealer to do.
WD40 will not effect the plug in a negative way,..it can only do good. Having said that, I dont think WD40 will assist getting the fill-plug out. IIRC, I had to use a short section of 1/2" drive from a tension-wrench kit inserted in the socket and a large shifter or combination spanner to turn it. It had to be "shocked" to undo,..then it came out easy.

Ah well... perhaps this one *is* best left to the dealer to do. ============================= There's a secret. You need to lift the car to get enough room to get at that fill plug. Once you do that, there's enough working room to remove it fairly simply. Since I'm always doing other work on the car when changing the differential fluid, and I also rotate the tires every 5,000 miles, when changing the oil, I lift both front and rear - makes access to the differential relatively easy. Here's how you lift the car. You need one or two hydraulic floor jacks and a stable floor. I have a garage with smooth concrete. With asphalt on a warm day, or a sloping surface, you could have a problem. Since the car weighs roughly 3,000 lbs., you need a 2 ton floor jack, plus some sturdy jack stands. Those 2 ton floor jacks are fairly inexpensive. I bought two long time back, one stopped working after a while, and I replaced it with a 3 ton, just for an extra margin of safety, but the 2 ton is smaller and fits under the rear of the car much better. First locate the structural cross members of the frame - large welded steel stampings that run sideways. In front the engine mounts are attached to them, in the rear the suspension locating arms are attached. These box frame members are strong enough to easily support the weight of the car. If you look carefully, you'll see a spherical "bump" front and rear, at the center, and this is where you place the hydraulic floor jack. Then lift the front of the car until the tires are off the ground. Place your jack stands on either side of the floor jack and slowly lower the floor jack until the force is evenly distributed between them. If you only have one floor jack, now you move to the rear. For the rear jack stands, place a 12" 2x4 piece of lumber on top to spread the load under the side jacking points where you have spot welds on the sheet metal, then lift from the center of the rear frame member, set the jack stands, and lower the jack to evenly distribute the load. You fill now find working under the car _much_ easier.
