Do you jack up the diffs to properly fill the diff?

Ahhh I see. So as long as it makes it down the tubes we're good. I imagine a little extra oil might have some cooling benefits though
 
Windshield washer fluid does not have to be accurate.

Making sure you’ve added enough gear oil to protect a major component of the drivetrain is pretty fookin’ important.

No need to be a passive-aggressive turdburglar to someone that’s trying to make certain they’re taking proper care of their investment.
 
Well I don’t check my gear oil level while doing service, so I don’t have that problem. If there’s no leak, there’s no where for it to go.

You don't check for contaminated gear oil when you service your jeep? Its not just about leaks.

If I did some water crossings or mud, I'd possibly be a little concerned about contamination, but I don't so I don't check it regularly. No need too. I'll just change it every 30k miles or so. I would say the rear axle you have pictured has seen some abuse and/or neglect well before this happened.
 
we don't rotate the front much due to needing to retain caster. so i trust the plug for level.
the rear pinion angle is jacked up and the pinion bearings are above the oil level, so i put what they recommend even if i have to dump it into the vent tube fitting to get it in. just to be sure i'm slingin as much as possible off that ring gear around inside that diff.

I would rather have a little less than spec in there instead of too much. As long as it partially immerses the gears so they pick up oil as it spins you're good. As others have said overfilled is not great for your seals.

Why would the seals care when there is a breather?

It's interesting to see the different opinions on this. I'm curious what recommendation a gear manufacturer might have?

Did I miss someone suggesting to run them dry?

"Making sure you’ve added enough gear oil to protect a major component of the drivetrain is pretty fookin’ important."

Sure is...that's why I advised if you can feel lube with your pinky finger you've got enough.

Engines and automatic transmissions are...how do you say...."pretty fookin important" as well, no?
They have a distick with an acceptable fill range.

Anything in the xxxxxxx's is perfectly satisfactory.

The diff pinky trick....I'm not breaking new ground here.
People have done this since pretty much forever.

Jacking the rear end can be useful if servicing the the diff cover gasket/rtv. It keeps the residual lube on the gears (that will drip for hours) from running outward to the opening allowing for some dry cure time of the new gasket/rtv.

Something tells me you miss a lot of things — social cues, mostly.

I’ll give you some credit, though: I didn’t quote you and you somehow knew it was you to which I was referring.

Good tip. look up the amount they say you should have in your diff. if you have axle tilt not allowing you to put that amount in get your cover off and tap a new fill point. BUT FILL THE SPEC AMOUNT ONLY. If your not comfortable doing that then maybe jacking is a very easy solutions. To little = axle death. To much fluid can cause a leak. BUT another thing. Check your vent tubes on your axels if your messing with them perfect time to make sure air can flow properly especially if your going to over fill that will blow some seals quick! Finger trick is very good for level axles. Im a lil sloppy and just fill mine till it spews out a lil and call it a day.

The question was asked if the vehicle needed jacked up to compensate for a pinion angle while filling with lube.

I answered that by simply stating it wasn't necessary whatsoever and if you can feel lube it's got enough.
If that simple answer hurt your feelings or ignited some need to go all in on the coddling police mode...too bad.
You're the epitome of today's societal decay. Hurt feelings, participation trophies, hugs and coddling, kleenex or puffs. All of which I don't give out and I'm not sorry for that. Good day.
 
(Blah, blah, blah, I didn’t get enough hugs as a child, blah, blah, blah, more passive-aggressive horseshit to make myself feel better, blah, blah, blah, I am very bad-ass.)
Yawn!

There are plenty more people on this forum who are legitimately helpful and not internet hardasses.

My ignore list population went up a tick today!
 
I’m going to be cleaning out my differentials when I get some time, and I’ve got a lift. This thread is bringing up a few good points I hadn’t thought to consider.

I checked out this video for some basic info. However, the guy in the video doesn’t say what he’s spraying in the differential to clean it out.

Is he using brake cleaner or something?
