Overfill Differential?

I am in the midst of changing the rear-end gear oil on my 4wd Tacoma. The manual spec says 4WD models and PreRunner 3.12 qt. (2.95 L, 2.60 Imp.qt.)

I am up to about 3.5 quarts, and it still hasn't spilled out of the fill port yet.

Should I follow the spec of 3.12, or fill until it spills out?

I did jack the car to one side, and then the other to make sure the old oil drained from the axle housing. Maybe that would account for it?

So, fill port or Toyota spec?

 

When i do mine I buy 4qts and take about 3.5. Is your truck slanted at all?

 

Slight incline, facing down hill, but not a half-quart's worth

Your's is a 2nd gen, right?

 

Yep 2011,rocking 69k miles

 

Just changed mine at 38k. Put in 3.10ish qts and called it a day. It didn't spill out but im not worried about it. I put my finger in there and could immediately feel fluid.

 

You could keep it in the same thread that you just made. Easier for when people search as well.

I don't think you could go wrong either way. 3.5 in or a little more until it flows out. It's probably right there almost to the overflow anyway. Even if you went over a bit due to a slight incline, it's not going to be enough to harm anything. Ultimately it has to be your call and what you're comfortable with.
