It takes 80w90 and you can get it in synthetic. You dont really need synthetic unless your towing in 4WD high all the time. I cant find the capacities anywhere except on Amsoils site. they list the front axle at 3 pints (1.5qt) and the rear 10 bolt 8.6 at 4.2pints (2.1qt) and rear (6.2L 9.5" 14 bolt) at 5.5pints (2.75qt) transfer case 3.2pt (1.6qt) I see on here others disagree. Id like to see some one with a factory service manual list the capacities.


Guess it might depend on year, but this is a screenshot of the page from my 2015 manual. it shows to fill cold up to 1mm from hole, and then check warm and fill to bottom of fill hole.......

Yeah, you're right. But here is the screenshot of the 2013 manual..... notice any similarities?

Screenshot 2016-11-28_22-14-28.jpg


Notice how both manuals say virtually the same thing.... to the bottom of the fill hole. At very least, 1/8" below fill hole when filling cold. Not even close to your 3/8" below you mention. But at warmed up temps, it states to fill to bottom of hole.

Would be nice if you actually read the manuals instead of thinking others do not have a clue.

But earliest manual I could find online is for 2009. here is that shot. Guess what? It says the same thing! Oh my goodness!

So, folks.... you can forget some mind numbing stuff about using a wire to measure things. Keep it simple. Fill to the bottom of the fill hole, cap it off, and call it a day. And in the keeping it simple idea, just use the same 75w90 you are using in the rear diff. It will work just fine. No need to buy 75w90 for the back and 80w90 for the front. They are the same viscosity, only difference is the cold flow rate, and the 75w90 flows better at cold temps than 80w90. So why not use it up front also? Viscosity is not "thickness". It is the measured resistance to flow.

Could you post the source for this information? Wouldn't want some one reading it and it be wrong, since the manual states otherwise.

Re: How to Change Front Differentail Fluid

Basically all three (Front and Read Differentials and Transfer Case) can all be filled to the bottom of the fill hole. The only exception is the rear differential which should be 1 mm to 19mm below the bottom of the fill hole. I consider 1 mm below the hole to be virtually the same as level with the bottom of the hole.
======================================================================
2013 Silverado Owners Manual - Chapter 10. Pages 29-32.

===============
Rear Differential:
To get an accurate reading, the vehicle should be on a level surface.
For all 4.3L, 4.8L and 5.3L 1500 Series applications, the proper level is 1mm to 19 mm (.04 in to .7 in) below the bottom of the fill hole, located on the rear axle. Add only enough fluid to reach the proper level.

For all 6.0L and 6.2L 1500 Series applications, the proper level is from 15 mm to 40 mm (0.6 in to 1.6 in) below the bottom of the fill plug hole, located on the rear axle. Add only enough fluid to reach the proper level.

For all 6.0 L 2500HD Series applications, the proper level is from 0 mm to 13 mm (0 to 0.5 in) below the bottom of the fill plug hole, located on the rear axle. Add only enough fluid to reach the proper level.

For all 6.6 L Duramax Diesel 2500HD Series applications and all 3500 Series applications, the proper level is from 17 mm to 21 mm (0.6 in to 0.8 in) below the bottom of the fill plug hole, located on the rear axle. Add only enough fluid to reach the proper level.
=====================================

Front Differential: This should be for all Series applications.
To get an accurate reading, the vehicle should be on a level surface.
When the differential is cold, add enough lubricant to raise the level from 0mm (0 in) to 3.2 mm (1/8 in) below the fill plug hole.

When the differential is at operating temperature (warm), add enough lubricant to raise the level to the bottom of the fill plug hole.
=====================================

Transfer Case:
To get an accurate reading, the vehicle should be on a level surface. If the level is below the bottom of the fill plug hole, located on the transfer case, some lubricant will need to be added. Add enough lubricant to raise the level to the bottom of the fill plug hole. Use care not to over tighten the plug.

Nice write up. Certainly wish I had a lift handy! Truck has 65k, looking to get both front and rear fluid changed soon.

You don't need a lift. A jack and two jack stands is plenty. I am fat, old and have a bad back and the jack stands work for me. But, yah, a lift would be handy, for that and many other services. Just don't let that keep you from doing the services. At 65K, I think it you should get that factory fluid changed out soon. Transfer case and transmission as well.

I wouldn't even use a jack and stands if possible, as it might not keep the truck level. If you need more room underneath, you can drive up on boards (under both sets of tires) to raise the truck. I'm skinny, but I fit pretty easily under my truck to do front diff, rear diff, and transfer case.
