How to Change Differential Oil

Need Help How do you guy's replace The differential Oil and what type?
4 Cyl 2009 Toyota Tacoma 2.7 Automatic.

 

Put a pan under it and remove the fill plug on the side. Remove the fill first because if for some reason you can not get it out after draining your screwed. After removing fill plug remove the drain plug on the bottom and let drain for 5 min or so. Clean area around drain plug and reinstall. With fill plug removed take your bottles of oil and cut the cap with wire cutters or a knife and hold them horizontal and squirt the new fluid in. When it overflows out the fill plug that is the proper amount, your vehicle needs to be level front to back and side to side when you do this.

Oils weight should be listed in your owners manual but I show it as 75W-85 and 1.43 quarts to fill.

It's a sticky at the top of the 2nd gen forum. Inside that thread there's also a rear diff guide.
Just did mine (plus TCase and MT) at 98k with Amsoil SevereGear

$30 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90. Ordered 9qt total for both diffs, tcase, and manual trans.

 

Good luck with the front diff. Make sure you have a good 10mm Allen socket and breaker bar. Make sure the Allen bit is firmly seated in the plug (may have to hammer it in), to avoid rounding it off.

 

Thank you for your Respond,But i have only rear differential.

 

Tank you for the info.

 

Thank you
1320Fastback I went to All auto part's stores around my area n they Don't carry the oil per The Book.
in the Dealer they toll me my truck use this oil $79.00 per qt, Do i need this??

 

For rear diffs, the higher the second number in the oil viscosity rating, the better. 75W85 is not as good as 75W90, which in turn is not as good as 75W120 or 75W140.

75W90 is the most common weight found in stores. Just buy whatever major brand (Mobil, Valvoline, Castrol, Lucas, Quaker...) that's on sale. Typical price is $12 per quart for synthetic.

 

75w90 is great in the rear diff!

 

$79/quart??? Good God are they thieves!! Are you sure they didn't say $79 for all 6 quarts needed?

 

Check eBay. I purchased some Toyota LT 75W85 gear oil for $20/liter including shipping. Local dealership price was $27 each at wholesale pricing plus sales tax.

 

That's why they call for a weird weight. People who won't do anything but what the manual says will pay it.

 

Just go to autozone and get this http://www.autozone.com/greases-and...il-sae-75w-90-32-oz-/373225_0_0?checkfit=true

Change it every 3rd oil change and drive the truck a million miles.

75w85 is a real bitch to find and that's why they charge a fortune for it. 90 weight instead of 85 when hot isn't enough to affect milage or risk bearing damage when driving. No way I'd put 140 weight in it though.

 

I've changed front, rear and transfer case three times in my truck. It calls for every 30,000 miles but I could easily go every 50,000...I don't tow or off road, just light hauling occasionally. The fluid doesn't usually look too bad when I drain it but man does that stuff stink!

I spend about $90 total on 6 Qts of synthetic 75/90 and a $10 transfer pump at Wally World. I always throw the pump away when I'm done....messy job.

 

Did you happen to get a quote from that dealer about how much they would charge to do all three changes? $79/Qt (6qts needed) would be $480 plus their labor...$600-$700 total, that's criminal!

 

How do you figure? That's a pretty general statement about a widely misunderstood topic.

 

ECGS calls for 85w-140 when you replace your third with one of their ring and pinion setups. I remember reading on an FJ forum once that a lot of them had been seeing a lot of pinion bearing wear on their rigs, many suspected that it was from using a thin oil. Then again, GM uses 75w-90 in their rear diffs and calls for 50k intervals following the severe service requirements.

Ah shit what happened to the front one?? Thieves?

 

This is on my list when the weather breaks in the Spring.
