For real that pump will leave you cussing and wiping up gear oil. Those suck horribly even when screwed atop the bottle. Ive probably bought 3 of them and they always leave stinky gear oil all over. Everywhere but where i want it.
It works extremely easily for me.
Bottom line is whatever little pump a person is comfortable with will work so long as you can stick a hose into the diff housing and connect it to the suck side of said pump. The nice thing about the one I suggested is they are cheap enough to throw away after one usage.
[QUOTE=messi;7518315]So I've been off roading quite a bit lately, ever since I put new coilovers and shocks along with lift on the truck (2022 3.5 EB). I do a lot of 4x4 mode in 4H and I've read that after about 500 miles of front diff being active is to do a fluid change. Hell, my rear end probably could use a fluid change too, I have almost 20k on the truck. My front diff seems to be easy to access after putting the lift on it (see pics below). Would I just take the cover off to drain the fluid, same as on the rear, and then put a new gasket on, then fill it up at the fill hole? If so, which gasket is the go to?
Also, what about the transfer case and do I need to change that fluid as well?
I have added a drain plug to just about every truck I have owned. I will eventually do this to my 2021 f150 front diff too. Not saying that it couldn't cause damage. I drill and tap a drain plug. Not a big plug😅 I recall using 3/8 but with the fill plug off. The gear oil should drain no problem. I do this because I like to change fluids every 30k.
