Gear oil yellow???

[mudbog42]

This may be a rookie question but popped the check plug off of my front differential and real thick yellow fluid just started pouring out.

Is there yellow fluid or is this bad? Also I thought that the fluid level should be just under the plug

Thoughts

Holy crap you have a yellow overflow situation..................!!




Nope that is normal. Once the G80-90 get spun around it gets a litte more yellow from the air bubbles in it. And having too much in the diff is not a big deal.

Was it kind of gewy. You could of got mud and water in your dif.

This is what water and mud look like in a diff.....

Dam thats bad I had some in mine but it was just enough to mix with the oil and change color to a yellow-brown.

It was just really thick and yellow but didn't look like it had any brown in it

I am sure it was fine

i drained my front diff today and i got the same yellow gooey stuff. either it's ok or we both got the same problem.

gear oil and rtv are cheap. pop the cover and reseal it. add all new gear oil. never hurts. who knows how long the oil in there has been in there.

If you checked it when it was hot that would account for the spilling out as the oil when hot expands. The oil will also be airated if checked after just having driven it so that would make it appear yellow in color.

Tanks for all the help

How often do you guys change your gear oil?

Mines been in for about 3 years now when I did the gear swap

Mine was in for 4 years until i recently swapped on new diff covers and the oil looked just like the day i put it in and also smelled the same too.
