Differential seems to be a black hole for fluid?

Okay so I drained the differential, the rear one, waited a long time, and then filled it up

I realize that it consumed all three bottles of mobile one without ever leaking out the fill hole... So I went to get another one just to be safe, I was seriously expecting it to only need a little bit more only to realize that I had basically just about filled it up with the entire bottle. So basically my differential holding almost four bottles of fluid...

What?

Should I keep going? Or should this be good? I just don't understand why it seems to not be full.

 

Okay so thankfully after laying the bottle sit for a while, it looks like it's got about 1/4 left.

But still, is this okay? I really don't want to mess anything up Lol

 

Is the vehicle level? If yes, and its dripping out the fill port you're good, no worries mate. It can only really leak out the axle seals and you would see that.

 

Yeah it's level, but what I'm saying is with 3 and 1/2 bottles it hasn't leaked it all out the fill hole, that's why I'm concerned haha..

Is there a bit of extra Tolerance? Like can it handle a bit extra without anything exploding?

 

Stick your finger in the fill hole to see ifyou canget your finger wet and if not I guess keep pumping it full of fluid

 

How long does it need to sit for it to be cool enough to touch? I've already hurt my pinky wants today I really don't want to hurt it again lol

I've filled probably hundreds of tacoma diffs without actually checking how much I've used. If it comes out the port its good.

 

Prerunner, and she's definitely at least at 3.5 quarts right now... :/

 

whats the manual say it takes?

 

How much fluid is left in the other bottles and how are you filling it?

 

The rear diff takes a lot of fluid. I was shocked at how much mine took before it started dripping. Just keep filling it. As long as the drain plug is in and it is on a flat surface, there is nowhere else for it to go really.

The Haynes service manual states 3 quarts even, but mine took a little bit more than that.

 

2013 mannual data.

 

Okay so I decided to close her up. With my pinky, and thankfully the fluid was not hot, it seems to be right at the edge of the hole. So I'm going to assume it's okay for now. I guess I'll wait a few days and then see if it wants any more.

Does it matter that I had just driven it?

 

Pretty sure fluid expands when it's warm I'd just wait until it's been sitting overnight or for a few hours and re check it but it should be fine if it was right under the hole

 

I’ve never looked at the required amount


Fill till it comes out the hole and then DONE.

Don’t worry about it.

 

Okay so I went down the road over towards the the mother unit's house, went down her Street which is bumpy and old. Didn't feel anything weird, got back and checked everything underneath, and it looks okay. So I guess I can call it a success.. lol

Damn auto correct!!!

 

I think it’s time you call it a day and have a cold one.

 

Good advice!

 

My God...autocorrect what have you done
