Time for my least favorite maintenance job. I have tried various pumps, suction guns, and funnels. The final outcome is the same. An oily mess! What is your secret?

Thanks all.

I use the tube made by flo-tool. it attached in place of the cap on the bottle of fluid, tip it upside down, turn the collar to open the valve and squeeze the bottle. best bang for the buck IMO.

I always refill with just the oil bottle and make no mess :shrug: my hand just gets tired.

Are you talking about this type of bottle?

No way can I get that high enough in my non-lifted KJ.

Quart bottle, warm it up as much as possible, tilt it up and pour it in
Lifted helps a lot as well , or just raise the body up off the suspension some
I hate those pumps etc that you buy from the ****zone places :thumbsdown:

I'm not lifted. Jack it up a bit. Gives the same angle on the differential as being lifted.

I never seem to have much trouble with mine, just roll under and BAM :icon_lol: Even 501s on the right isn't too bad to get to. A lift serves more than one purpose for lazy folks :ROFLJest:

Thanks for the input everyone. Getting the oil warm might help because flow rate seems to always be slow. Plus it introduces the burn factor! :icon_lol: And here I thought this job couldn't be any more fun!

I used a $7 pump I got at Harbor Freight and had no trouble. Dropped the intake in the gallon jug of gear oil and went to town.

All I ever use is the bottle the oil comes in (like above) with a short section of clear hose (to monitor flow) wedged onto the tapered cap. You can have the bottle horizontally at a downward angle as long as the tip is higher than the fill hole, bottle doesn't have to be vertical. You can get the hose at Home Dopey.

Just put the jeep up on jack stands and fill the differential by just squeezing the bottle into the fill hole and I have no problems doing this with my libby even without a lift.

I always change mine in the summer. I did do it in the winter once.... once.

I use one of those inexpensive hand pumps (like above) now if I use the gallon but never had trouble doing it the squeeze quart way with the hose like CactusJacked.

This is EXACTLY what I do. If anything, I get a drop or two on myself, but no more.

How do you guys do the front? Last time I had to use a hand pump and the time before that I had to keep switching to a new bottle/combine them when they reached half.

I find the place where I can stick the bottle as high as possible. I've never needed a third bottle nor a pump.
