2020 Denali HD Front and Rear Diff Fluid Change

As the title says.

[@completemoney]

Love how everyone has their own opinions and most say you’re wrong doing this so early. Literally the only way to know if you have premature issues at 50k is to change all fluids. Literally nothing wrong with doing what you’re doing.

I've been thinking about getting the Banks Diff Cover. I just love everything Banks LOL .Thank you! Awesome Video Once Again!

[@nickwarren5800]

Great video showing proccess. Im changing mine at 75k as I never tow. Your fluid still looked really good.

[@nordicpride9708]

You can’t judge an oil by appearance… literally means ZERO. It must be analyzed in a lab to ascertain its state of health and ability to protect. This isn’t an opinion, it’s a fact.

[@fondupot]

It’s nice they still have the drain plugs on the heavy duty trucks. The 1500’s don’t have drain plugs on the diffs anymore. Nice video.

[@OnTheToolsWithSal]

I’m getting ready to do mine on my 2020 1500. Sucks that we gotta pull the covers to drain… so cheesy

[@EfrainManuel-p9b]

GREAT VIDEO!

[@hongs8867]

You NEVER take out drain plug before loosening the fill plug.

[@andrewr2650]

Thanks for the video, I just did the transfer case on mine, not bad at all. I was surprised to hear you were having the trans serviced at 50k (45), which is the severe service interval. normal use is 90k. The stuff you do with your truck didn’t sound severe considering the same driveline can pull 30+K with DRW. (Different rear axle but Still the same final ratio) I guess you do have the banks on there, and of course it’s your truck and your money so you get to decide!

[@harrisonfowler4461]

Were those actually magnets in those plugs? I changed mine and I didn’t have any shavings or anything on them. 45k miles almost exactly.

[@RandyAndersen-ie5jt]

Just an FYI, apparently in 2022, GM has ordered axles for the HD without drain plugs front and rear. My 22 HD Dmax does not have them. So, either suck it out through the fill hole which leaves the residue in the bottom, or get pan gaskets to do it properly. All my trucks back to 2001 have had drain plugs for the axles.

[@randyandersen6888]

@@jhb3711 My 2022 Silverado with a Duramax does not have drain plugs on the axles - I looked - it only has fill plugs. The dimple on the axle casing is there where it should be on both axles, but there are no drain plugs.

@@randyandersen6888 i apologize. You are correct.

[@mikeverderame8330]

I have a 2021 HD Sierra with no drain plug either, I saw this video and was angry they used to have it in 2020 😡

[@jimbrown6483]

THANKS MAN, Now I know ✌️👍

[@kaufmankdk]

How Many of the Asmoil containers were used ? Each container is 1 Quart, looked like 2 used.

Wild move to work on your truck in flip flops player

[@FROGMAN524]

Lol

[@jaypiva1951]

Per GM= front diff quantity is 1.9 quarts and rear is 3.18 quarts. I'd say you have over filled both.

[@hongs8867]

Transfer case is so simple

[@DuraMaxDieHard101]

Did you get better mpg after changing to Amsoil?

[@alphaforce6998]

Really dude?

Bro what do you mean?? I actually did the transfer case on my 2021 watching your video for you older truck. And I’m jealous there’s no drain plugs on my differentials ):

[@FROGMAN524]

The T case on the 2020/21/22 fill plug is right in front of the cross member. I didn’t feel like dealing with buying a hose and a 90 fitting to do the fill

[@samueldamianreyes7602]

@@FROGMAN524 my ‘’21 might be a bit different from yours cuz I had a pretty easy time with the fluid change using your video for the older truck. Which btw thanks a lot brother, love your videos.

The rear diff oil was still goof

[@mikebrudos8159]

Just knock the two flanges off the banks cover.

[@FROGMAN524]

Not paying $500 and destroying the cover. Thanks for your wisdom though.

[@alphaforce6998]

Literally no reason to be changing diff fluid on a brand new truck... but at least he's using all-natural snake oil on them gears.

[@DrSamBeckett]

How so?

[@nordicpride9708]

Coming from someone with exactly ZERO experience using UOA’s (used oil analysis) in a fleet environment… yeah I’d say you are VERY wrong. Getting the wear metals out early is the single most important thing you can do to increase differential life. I don’t care what fluid you use as long as it meets the recommended specs and environment/operational use.

[@alphaforce6998]

@@nordicpride9708 Well, I appreciate that you announce your lack of experience. I, on the other hand, have a lot of experience spanning decades and NOT ONCE have I experienced mechanical failure due to not changing diff fluid excessively or unnecessarily. Tiny shavings in the fluid are not going to contribute to wear; and if you have anything larger than that in the fluid you have other problems.
