Lubricants for axles - how are they different from gear oils?

Lubricants for axles and differentials occupy a unique place in the industry. They're at the same time a consumer product, a commercial product, a product not really intended to be changed by consumers, and with few specifications surrounding them. So what are the requirements for these lubricants?

[@tcmtech7515]

This is why I love working with old-school equipment. If the lubricant had a lubricity anything better than rusty water it was more than good enough to do the job.

Excellent input to be adopted in every workshop DAILY 👍

Thanks!

This channel is amazing, filling a knowledge hole I’ve had for a long time

[@benjaminchu6699]

great explanations and great work as always 🙂

[@free2chasehappy]

Great information! Fluid selection is very important and people need to understand it.

[@LubricationExplained]

Thanks!

Could you do a video on multi-rated gear oils? I mean gear oils which specify both GL-4 and GL-5 on the same bottle. How are the different from gear oils which specify just one of the standards?

One thing I have learned with my 2017 ram 2500 with anti-spin Is that traction control virtually renders the anti-spin useless. Unless I totally turn the TC off - which is another can of worms.

@ 7:10 you are saying that clutch plates absorb the force/torque of right hand wheels and transfer them to left hand wheel,but still at starting point slip occurs?Thank you.

[@FairladyS130]

Excellent. As far as a clutch type LSD goes, if it's aftermarket and no oil recommendation except use 140 grade is given, how does one work out what oil to use

[@bobbowie5334]

This one that you're going to have to learn about the _hard way._

[@besssam]

Burning the midnight oil ! ... What's the preffered chemistry for that? lol

[@imperatormouse2735]

10W-60

[@zzman5306]

Synthetic

[@ch0wned]

Tropanes.

[@seanc5827]

Ending was abrupt. Otherwise, good information

[@davidwillmore]

In a viscous LSD, wouldn't you want an oil that behaved like a non-Newtonain fluid?

[@needmoreboost6369]

Like silicone oils? corn starch is a poor lubricant

[@FairladyS130]

In my experience a viscous LSD has the working part sealed so the diff oil would be OE recommended.

[@ngrinshift4383]

For the viscose diff I wonder if they ever used a Newtonian fluid?

[@kensutherland414]

Thanks mate. Do you have any info on pinion heights. I know hypoid is below the crow wheel and I think genius is level and snood is above. Due to the pinion helix being different do they need different? Cheers

[@joebrown9621]

Some OEM. Recommends 80W90 for front and rear diff however 75W-90 for the tans.. i thought 75W-90 would be a superior oil thus used in all 3.. ??🤔

[@gregorymalchuk272]

Hey, I have a rather stupid question. What exteme pressure additive is used in hypoid gear oils that make them smell rather like armpit sweat?

[@Antique803]

Does using the wrong fluid damage the lsd ?

[@Olenappy]

Yes

[@CJ5EVOLUTION]

What is the difference between GL-4 and GL-5 additive package?

[@zzman5306]

Better additive pack and better protection.

[@alphabeta123100]

Hello ! Is differential oil is the same as transfer case oil ? I am owning a Toyota rav4 4WD diesel automatic transmission 2018 model .

[@zzman5306]

They often are. Check your owners manual

[@alphabeta123100]

@@zzman5306 I did almost the same thing , thank you 🙏

[@KarolosAthens]

Very Fantastic article !!!!!!!!! ViscoDrive / Haldex / Torsen......ANSI/AGMA GL6+ STAYEUR PUCH .

[@rud8051]

can u substitute 80w90 non syn with 75w90 synthetic ?

[@johnready630]

yes

[@FreedomIsNotFree999]

To much bs get to the point fudge can do better 😂

[@rollling7523]

Welded differentials are the best

[@michaelb7071]

If one intends to wreck their tires and axles it is indeed.
