Perhaps a mod could sticky this at the beginning...if it's not already there

Fill and drain plug washers are the same. So you'll need 2

 

Good info, but that (and more) has been previously captured and reposted to this thread, though not stickied...

 

I thought for sure it had. But I couldn't find it stickied anywhere

 

I did my 1st diff service 2 years ago at 30k miles. I went with Mobile1

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

75w-90. Just did my 2nd service today at 60k miles. The old oil looked really good. Not very dark and no floaters. Magnet was nearly clean. I went with M1 again. And just like the 1st service, it took just over 3 quarts.

Stock '15 Sport Prerunner, no towing, 2/3 highway, 1/3 city driving, 60k miles.

 

Got the Front Diff / T-Case / Rear Diff all done today. All in all, a very straightforward project heavily assisted by the quart pump. That little pump was a lifesaver and made it very easy to track fluid quantities of everything. Bought that $12 gasket/washer kit from Amazon and it had everything as needed.

Front diff oil was nasty. It still had some opacity, but it was very dark. No shavings.

T-case oil looked like brand new. Definitely the easiest of the 3.

Rear diff oil was only slightly darker than the T-case oil but still very clear. I did come across this tiny dome shaped shaving on the magnetic drain plug. It's a little smaller than a pencil eraser, and about as thin as a piece of construction paper. Any idea what it could've been?

 

Piece of the henway broke off

 

Anything to be concerned about?

 

You have the link to the washer/gaskets?

 

Yes sir.

My rear diff drain plug had the same dome shaped piece of steel.......

 

No idea what it is. Never had a single issue with the truck. Glad the magnet caught it.

 

Will the washers posted over the past few pages work with 3rd gen?

I’m poised to buy this kit (which includes different sizes) just in case.

If the plug sizes are the same then I don't see why they wouldn't

 

How may quarts do you beed to do all 3

 

6 quarts will do front diff, xfer case and rear diff. I buy 6 quarts at a time along with the gasket set and just do them all at once.

 

That'd be my recommendation, too. The front diff takes the longest. Make sure you have the right tools and you remove your skids. The T-Case is easiest. You can be through with it in like 5-10 mins. Rear diff is easy too, just takes time to get that 3 quarts pumped in.

 

Thank you
