Differential Drain plug

Is there a special sized tool that fits into the plug to drain & fill the rear fluid on B?
 
You can make a tool to fit that plug pretty easily; I took a 3/8"-1/2" adapter (the cheaper the better in this case) and filed the flats down to make them fit the plug. You can do the same thing with a 1/2" drive extension too. Works very well IMHO.

That's what I started to do when I realised that the my 1/2" drive did not fit. Figured there is no turning back if I took out the drian plug and then could not remove the filler plug.
Best way to fill would be to use the bottle with a piece of hose attached right? Not a lot of room back there to squeeze the bottle.
 
Actually, I used a big funnel with a long hose and a tapered tip to fill it. Also handy for filling the transmission. I found it at Autozone for a few bucks, and it's been useful in many ways.
 
I'm gonna give away one of Horsemits' "design by necessity" tricks here:

Acquire a 1-quart "Ziplock" bag, the cap, screw-on bottle top and the first 1.5" off the top on the plastic bottle of gear oil (quart size). You will take a bottom corner of the bag, hold the screw-on nozzle on the outside corner, thread the bottle "neck" into the cap from the inside of the bag... think "pastry bag" here... once it's screwed on snugly, poke the center to open it up, put the cap on the nozzle and fill the bag half way with the required lube and zip closed. Best if you allow as little air as possible. Dive under the car, and with the cap off, squeeze it into the filler hole. You can meter how much oil you're adding by the amount you put in the bag. Toss it when finished, it takes minutes to fab up a new one.

Thank Herself for the nifty solution to a PITA job. /ubbthreads/images/graemlins/grin.gif
 
I use a gear oil pump that fits an empty gallon jug. It has a fitting that clips into the filler hole; just pour the correct amount of oil into the jug, hook it up, and pump until empty.

I do this for the gearbox and rear axle. This works for both the top and side fill gearboxes.

Do be sure, as Dave said above, to make sure that you can get the fill plug off before you take off the drain. If worse comes to worse, and the plug's stuck on beyond your ability to remove it, you can take it to a shop under it's own power rather than having to call a tow. I've had a couple of friends in similar situations.
 
One more argument for Anti-seize.

This conjures up an idea. Can you use a pump style shampoo bottle. I wonder if that would work with a hose attached to it?
 
I imagine it would work as long as you can: A) Keep the hose attached to the pump, and B) the oil doesn't eat up any of the shampoo bottle's pump innards. I don't think it would eat any of the pumps innards, but I've seen stranger things happen.
 
I don't see why a pump shampoo bottle wouldn't work; same principle, different means of getting there.
 
I'll keep using the "pastry bag". They're FREE, and fit into places where no solid container will work.
 
I used an old injector for bar-b-que. Worked great for the trans but time consuming. Love Doc's idea and will share it with my son when he works on his 4X4. "Here son let me show you how we did this in my day."

Still working on getting to the store to get a cheapie 1/2" adaptor I can grind down. I was also thinking of an old style oil can with the flexible shaft/tip, but the gear oil might not pump through that well.
 
Some auto supply stores, Pep Boys, Auto Zone, etc, sell a small plastic pump just for gear oil. You just screw it it the top of the jug and pump. Works very well. /ubbthreads/images/graemlins/cheers.gif PJ
