You'd think it was a 15 min process. Nope. It comes out quick but takes forever to pour in the new stuff. (OEM LSD Oil) I bought a suction pump, primed it and that was a total POS and wasted oil. I had to resort to a syringe I use for frying turkeys and some rubber hose. Pumped in 1 oz of fluid at a time. :eek4: Would have been easier to just buy the gear oil at Autozone since it has the squirter built in.
Alex came up with a great solution. Basically it is a hand pump out of a giant soap bottle with a piece of sillicon hose on the end that you can stick in the fill hole
When using the suction pump, it would pump the oil in the diff when I squeezed it but it never would expand again.
Yeah, Motul 300 is too damn expensive to spill. Especially when I can buy 5 quarts, and perfectly change your tranny/front diff. and rear diff. with not a drop left over. (4.1 qt. tranny, .9 qt. rear diff... and these are dry fills even). When I did mine (at 2000 miles, sigh) my Dad and I made a home-made manifold that pushed the "insert favorite fluid here" wherever you wanted it.Basically we used a valve stem on the canister (see image below and use your imagination) coupled with a bicycle tire pump. The fluid pickup tube connected to both sides of a nipple, then a tube inside the container ran to the bottom. Worked flawlessly for trans/front diff. and rear diff. filling. You could use an air chuck as well I guess, but the pressure better be regulated way down. It might not even go low enough honestly on most compressors/regulators. Basically we used an oversized mason jar. Had the other part lying around. It had a screw-type metal ring and metal lid with a rubber gasket underneath, so the pressure seal was excellent. I'd say if you did a lot of tough to get to fluid changes it would be advantageous to maybe spend 30 minutes and construct one of these. I'd take pictures of the one we made, but he lives too far and it is at his house.
Just get a long length of tubing (6-10 feet). It must be able to fit into the fill hole. Have someone hold one end in the fill hole and run the other end out from under the car and get it higher than the diff. Pour your fluid into that using a funnel. I have also used the suction pump - I agree it sucked - no pun intended! It did leak badly.
I've accidentally gotten about every automobile related fluid in my mouth at one point or another in my life (touche), and none of them were that great. I will say the cherry flavored coolant is by far the best though. Lithium grease is good on bagels too.
Did you enjoy that 30mm wrench? :rofl: An alternative is to remove the drain plug from the trunk and run a hose through there into the diff. Then you can pour while standing up! Just dont miss
That actually crossed my mind. I sold the car to a guy in Augusta, GA. Nice guy. He's in the Navy and will be driving to San Diego tomorrow with the car.
This is a fairly good summary. I was purchasing specific sized containers from McMaster car for the Extra-S I was list on JPM's website. When it came time to do my rear diff I refused to succumb to the folly's of past attempts and decided to use some commonsense. I went to a Napa parts store and found a hand pump that came with a tube. The base of the pump was approximately 3-4" and had a nipple on it so that you could add another tube (included) in case your container was deeper / larger. The specific reason why I went with this pump is because the base had a threaded cap. As luck would have it, this threading matched my containers and boom. Instant no-mess easyness.
