Hey, which Motive Power Filler did you get? Is there one in particular which makes working with gear lube easy (ie- has a large hose out?) I jury rigged an old 5 quart oil jug with a Schrader valve on it and a hose coming out, to pressurize it and force gear oil out. It worked - until I overfilled it with pressured air and the jug exploded and gear oil went Everywhere. It was ridiculous. Fortunately, I had goggles and ear plugs in use, and was wearing overalls. Still, it was a ridiculous failure. I don't recommend trying that.yeah I bought it before all the Lexus plug stuff was posted. or I saw it anyway, oh well.. it's done and should be easy from now on for the annual service I normally do on my trucks (diffs are done annually on my other trucks, what's one more) - I did also finally get a Motive power Fill as well, should have bought this thing years ago. makes filling diffs, transfer boxes, etc a totally breeze.
