DIY Rear Differential Fluid Change on the Camaro ZL1 1LE

[@tlalexander3]

Nice. I have some of this differential oil on the way for my 2018 SS 1LE. I have 30,000 miles on it. Today, I got on it at a light and I had two warning lights come up that said service rear axle and service stabilitrak. I don't feel anything weird going on but every time the traction control light comes on, so does the other lights. The soonest appointment I could get was the 17th at the Chevrolet dealer (I still have a 6 year, 100,000 mile powertrain warranty), so I figured the least I could do was to change this oil and maybe that'll solve my issues.

[@BROCKgoFAST]

Oh man, yeah I would do the change and see what happens. with the eLSD GM recommends the first change at 1500 miles I believe to get the break in fluid out.

[@matt-ts8cx]

Definitely use jack stands as a safety... too many people have had those quick jacks come down on their own

[@BROCKgoFAST]

Always do!

[@sportscarnut]

I suspect there is a solid lubricant like molybdenum in the drained diff fluid with its dark color and material on the plug. Moly is a great additive for diffs and some transmissions.

[@BROCKgoFAST]

Not sure. I know some of it is the differential wearing in

[@sportscarnut]

@@BROCKgoFAST Not certain. The diff wearing in would show as metal shavings. Moly is black and does protect moving gears.

[@BROCKgoFAST]

@@sportscarnut it was nice and sparkly the first time haha. From what I’ve seen the first is always the sludgy one

[@keithcastleberry3993]

Just doing mine at 9700 miles and looks like brand new fluid. Minimal gunk on magnets and light brown translucent fluid drained out. 2021 2SS. Hope thats good news.

[@BROCKgoFAST]

That’s great!

[@hyper1le486]

Track only for my ZL1,, I change my rear diff fluid after every track day. And 0-W40 Mobile 1oil with a Wix XP filter.

[@BROCKgoFAST]

Awesome. I’m going to change mine after my next track day

[@hyper1le486]

You ever been to Barber Motor sports park for track day??

[@BROCKgoFAST]

@@hyper1le486 I have not

[@AllIsWell_22]

Awesome Content! Can you show us how to turn the front struts 180' to achieve Max camber? A step by step instruction will go a long way for the community. A track alignment will have to follow of course!

[@BROCKgoFAST]

Thanks and sure I can do that. I have to get the street alignment put back on so i can do that here in a week or two

[@THEDriverMod_]

Reach out to me next time you need fluids! Got it all covered from front to rear. Price for the Amsoil gear oil would have actually been about the same believe it or not. I figured the OEM fluid would have been significantly cheaper so with that said why not use the better fluid? Suprise to see it only too that low of an amount. The GT350 takes between 2 and 3 qts

[@BROCKgoFAST]

For sure will do. Is the Amsoil stuff specifically made for the Electronic LSD?

[@THEDriverMod_]

@@BROCKgoFAST it's compatible with limited slip diffs whether they are electronic or mechanical. They also sell friction modifier if you experience any chatter as well. Electronic vs mechanical is just a different way of actuation of the clutches. Not much more than that. Their stuff exceeds all the GL-5 specs which is the spec for most differentials now days. Good idea getting it done before Sebring

[@keith455]

Also the amsoil gear fluid now comes in a bag that you can just squeeze. No need for the pump.

[@BROCKgoFAST]

@@keith455 I like that

[@THEDriverMod_]

@@keith455 the easy pack you refer to works for some cars, others, like the GT350, it does not because the diffuser and cooler lines are in the way

[@romikidorris36]

Where did you get the QuickJack

[@BROCKgoFAST]

Direct from Quickjack when they are doing deals

[@sebastiang7183]

Do you know the part numbers for the gasket/o-ring for the drain plugs?

[@BROCKgoFAST]

I don’t unfortunately. Try GM Parts direct

[@sebastiang7183]

@@BROCKgoFAST I have not been successful. I did find the part number for the plug that comes with a gasket, but not for just the gasket.

[@BROCKgoFAST]

@@sebastiang7183 they might not sell just the gasket

[@sebastiang7183]

@@BROCKgoFAST I find that hard to believe. You would have to buy the plug to get the gasket. There is a part number for it. I just have to find it or ask someone at the parts counter at a dealer.

[@HemiBurns]

Great video (as usual) my brutha!

[@BROCKgoFAST]

Thanks buddy!

[@matt-ts8cx]

Use the amsoil bags, much easier and amsoil is always superior in my opinion

[@BROCKgoFAST]

The OEM rear diff fluid is pretty good and they do want it to be specific for the e-LSD

[@matt-ts8cx]

@@BROCKgoFAST after doing a lot more research I have to agree with you. I am going to use the OEM fluid. Too many mixed reviews with amsoil. I will still be using amsoil for the engine oil though.

[@matt-ts8cx]

@@BROCKgoFAST just fyi, your KZbin video on the Corsa exhaust sold me on the extreme catback. I installed it a few weeks ago, sounds awesome

[@BROCKgoFAST]

@@matt-ts8cx amazing!! So glad you like it! It truly is in my opinion the best sounding exhaust for this car. It really is what it needed

[@BROCKgoFAST]

@@matt-ts8cx yeah for the rear diff it seems to really like the OEM fluid.

First Official Use of the QuickJacks! You are Going To Love Them! 🤙🤙😎!

Definitely makes it a lot less scarier with these new cars. I still put kicks under the car just in case lol

[@blackwhyd]

Hi I’m french and not easy to make it change oil by french garages… could you tell me how much oil is there in thé gear when you fill it ? And second question : Are your tools metric or inches for thé two kind of screws? Thanks yves

[@BROCKgoFAST]

No problem. You will need two bottles and it will use about 1 1/2 bottles to complete. My tools are both metric and standard. To be able to get the plugs out you will use the end of a standard ratchet

[@blackwhyd]

@@BROCKgoFAST super thanks from France 🤗🤗🤗🤗

What's the torque spec on the plugs?

[@normanhanna2037]

Dude you need a rear end supplement for that car I have a 2020 Z L11le i change it at 2500 use only gm fluid

[@normanhanna2037]

Supplement is gm

[@BROCKgoFAST]

I’m confused on what you are saying. The fluid is OEM and OEM part number. Supposed to change it at 500 and 1500 miles I believe for break in. I track the car so changing early is part of the game.

[@StrideX21]

Boight my zl1 with 3100 miles on it. Just changed the oil at 8100 miles but i never did this

[@BROCKgoFAST]

I recommend doing this. The first 2 are at 500 and 1500 miles I believe. Super easy and quick

[@Mac7504-OG]

30 mins of pumping??? Wtf!!!! I'm at 1500 and want to do this but I haven't pumped for 30 mins since I was in high school!!!!

[@BROCKgoFAST]

Lol start practicing
