Question when changing differential oil

[mpaquette]

What's everyone using to pump oil into their differentials when changing it out? I've been changing my own engine oil for 25 years, but have never done a differential. It doesn't look that difficult so I'd just assume do it myself and skip all the fun involved in letting a dealer "service" my truck.

I use a pump I got at a local auto parts store. Something similar to this: Attwood Gear Lube Pump: Automotive : Walmart.com
