Welcome back to another 10 minute job, today we change the fluid in the rear differential of my 2015 Silverado 1500 4x4, this procedure should apply to all 2014-19 Silverado and Sierra 1500 4x4 models.

Great video. I believe the range for my 4x4 2016 Silverado with a 5.3L motor is 0.04" to 0.70". The .04 limit is near the thread depth, so nearly up to the hole. I used 2.5 quarts of fluid to fill and was about 0.30" below the hole.

From the service literature, the INSPECTION levels from the factory are a range as they are filled with a certain volume that will result in variation of the fill level relative to the fill plug, so if the fluid is inspected and found to be within the range, then no fluid needs to be added. If the fluid is below the minimum, then fill to the bottom edge of the plug opening. Copy and paste from service literature: Inspect the lubricant level: Specification: The lubricant level should be between 1-19 mm (0.04-0.75 in) below the fill plug opening for the 8.6 inch axle. The lubricant level should be between 15-40 mm (0.59-1.57 in) below the fill plug opening for the 9.5/9.76 inch LD axle. If the level is low, add lubricant until the level is even with the bottom edge of the fill plug opening. Use the proper fluid. Refer to Fluid and Lubricant Recommendations.

Awesome video bro can’t wait for you to start on your sons truck 🛻 👍

[@williamrodriguez2317]

I've seen a few videos on this and no one mentions the bottom magnet on the enclosure. Thanks for pointing it out. Some of the other videos also fill up to the point of where it begins to drain out of out of the fill hole. Would this cause issues rather than using your method, or is it a rather safe than sorry situation?

I'd say once you are beyond your warranty it's a matter of opinion, personally I stick with what is recommended. Now this is the first diff I've seen that didn't say to fill until it flows out so I think you'll be fine either way! Thanks for watching and commenting!

[@bwilson1649]

According to details posted in another video, the range for a Silverado 1500 with the 5.3L motor is .04" to .70". With the larger V8, it is as stated in this video. Different for the 2500.

i have sierra 2017 base 6 4.3 same process ? thanks

[@bad550me]

like your video's but really don't need any music

[@fig2769]

Does the LS additive make a difference?

[@mannycastro2616]

Great video, Thanks for the help! 👍🏽

[@newdogatplay]

Why is it that u cant put the new stuff in an let it force out the old stuff like the older trucks was wen useing 90weight gear oil

[@nathanielphillippi2242]

Wouldn’t you wanna replace the diff gasket?

[@fzy55]

Just to confirm: 2.75 quart (75w 85) for the rear differential fluid change; how much needed for the front differential fluid change? the owner manual recommend using 75w 90 for the front, can I use 75W 85 for the front too?

[@nordicpride9708]

75w-85 vs 75w-90 in synthetic is a negligible CAFE fuel economy thing. You probably won’t see a difference in MPG between the two, and definitely won’t hurt anything running thicker oil.

[@fzy55]

@@nordicpride9708 thanks!

[@raylaingsburg3645]

Amsoil recommended 75-90 for both

[@OmarHernandez-pk5mp]

You guys complain to much about music bunch of little girls.. my god

[@caseG80]

Blast that shit had me grooving cheers !!

[@joeschimpf5650]

Drop the spare tire.............much more room that way.

[@raylaingsburg3645]

I'm glad I read the comments. This is a pretty obvious recommendation but something I would have overlooked. We dropped the spare based on your recommendation. Thank you.

[@misterinvincible]

completely unnecessary unless you're obese

Please turn down your muzak. I want to hear what you say, but getting my ears blasted by the music is unpleasant. Thank you.
