Rear Diff 1/3 qt. low

Tech found my rear differential 1/3 quart low during my last free Toyota Care 25K free oil change. No leaks.

Another factory low fluid level to be aware of.

 

there is a thread on this already. 0.33 out of 4qts isn't going to hurt a diff.

 

I've had my truck back to Fannin Toyota 3 times each time fluid levels low. So yesterday I took it upon myself to check my differential... It was 20 ounces low!!! The fluid was black. I'll add pics later today.

I changed the front diff tonight. Only 40oz. came out! 2.1qts or approximately 68oz to fill.

 

I think the actual level in relationship to the gears is as important as the volume of oil. Too low, it won't get picked up and distributed properly; to high, you can get frothing.

 

sorry but your not really low. there will be some still sitting up in the gears that havnt dripped off. you might get if you got every last drop out been like 1/8 qt low
thats not going to do anything.

 

I'm sorry... Your truck shifts smoother because you replaced your diff oil?

 

lol yea I dont think that would be.
I will say one thing. When I changed my diff oil at 2000miles my MPG have gone up around 1.5+mpg and havnt dropped
I am getting like 19-20mpg on my drive to work daily now before I use to get around 17.5mpg to work and I didnt use anything special. just that Synthetic blend walmart brand the Supertech 75w90

 

explain HOW diff fluid would make the trans shift better. I can understand if you get better MPG but diff fluid isnt gonna make the trans act any better or worse

 

This is TacomaWorld and he has the freedom of speech guaranteed by the first ammendment....

 

Riiiight... My bad, forgot this was 3rd Gen, which means nothing has to make sense

 

Don't forget to top up your gas tank after the pump shuts off and inflate your tires to a minimum 40psi otherwise your truck might not shift smoothly

 

Funny how people think whether the diff is properly lubricated would affect the shift points of the transmission smh

 

Just returning the favor

 

You will also gain about that much going from winter to summer and vice versa, so it would be hard to make the diff correlation unless you bought after March-ish.

 

That's not even low. A lot of oil doesn't drain out. There's some in the axle tubes. In the gears. Changing your diff fluid doesn't make your truck shift smoother

 

well the MPG increase started the day after I did the fluid change and I did my fluid change back around Mid to late April
