Jerry, I do use one very similar to this for transmission oil and t-case fluids..... But highly suggest a second set of hands to use this one...

That's how I do it when I service the gear oil in my differentials. No special tools needed (although I do use a hose clamp to keep the hose from coming off the bottle). Simply drain and refill with the diff cover in place.

However, for the 500 mile gear oil change after a re-gear which does require removing the diff cover to inspect the newly broken-in gears, I still prefer to have the gear installer do the work so we can inspect the gears together. Besides, removing and replacing the diff cover can be a messy job that I prefer not to do in my own driveway.

That's what Iím using. Works great when you have someone else to hold the hoses in place. When I use it by myself I usually make a mess.

I know it looks similar, but I've had good luck with this brand. The pickup tubes are stiffer, and stay attached. Got mine at O'reilys.
Pumps an ounce at a time, and can be disassembled to clean. One hand on the output hose and one on the pump. No problems.

I'll look around for one of those, thanks. My previous pump like that but a different brand is now at the town dump.

When you have a choice, buy American made.

I've been using the Plews 55001. They're about $7ea and last just long enough for both diffs. With how messy they end up I'd rather throw it away than pay double and have to store the mess.

Thats what I use too, so far it has worked pretty well.

For diffs, I cut the tip and squeeze the bottle. Use a long hose for tcase.

Ive always wanted a metal 5 gallon pump, but would need one with a quart counter. I have a bunch of vehicles and all have different capacities.

OP here: Scheduled the diff gear oil change for this upcoming Wednesday at the installer (Suburban Driveline in Villa Park, IL). I confirmed they remove the diff cover to drain and inspect. Will report back once the job is complete.

With 3 vehicles to maintain it's cheaper to buy a 5 gallon pail of gear oil and a lot cleaner to use a hand pump.

I use one of these for the transmission/transfer case fluid for my CJ, WAY easier than using the hand pumps, especially for thick oil.
