Thank you for actually breaking apart the diffs so I can visually see the mechanisms inside. Took you under 2 min to explain something other 10 min videos couldn't.

Interesting experiment. The quick edit was good too, right to the point. Thanks!

Thanks for showing this as a practical experiment

Nice and simple. Great learning moment, sir !! Hypoid gears always have a tangental force that makes them want to separate, thus enhancing the effectiveness of the respective clutch pack.
@phillip_mcguinness7025 2 years ago

The important thing to remember is that the force required to move the wheels separately is dynamic, because when torque is applied from the drive shaft the spider gears will try to spread apart increasing pressure to the clutch packs.

Thanks for getting straight to the point no bs for 4 mins before hand

Thanks for sharing this video. It's much easier to understand when looking at the actual component. Looking forward to see more videos like this.

Dude! Great job! We definitely owe you a beer! Really like your torque wrench! I have a similar one that was my mother's in WWII where she was an airplane mechanic!!

Super educational bro, I appreciate this becuase it helps me understand in a much simpler way than most other videos

Really good demo and explanation of the limit of a limited slip diff.

It was very important your video to me , because I have 2 hilux’s , one with LSD 2008 and other one with out LSD 2002 , recently found the difference and I thought it’s a issue and almost going to garage for repair , so Thanks to you now I know it’s normal 😊

Great to see a real measurement done live like this. As others pointed out, the clutch torque increases as the ratio of torques coming in from the wheels (from brakes or road reaction torques) climb. What you were really measuring there was the preload torque, the minimum locking torque the diff will provide. Very cool to see, thanks!

Limited slips carriers have a ramp like cam action to place even more squeezing pressure to either side of the clutch packs when slip occurs to increase the locking effect. The test you did is still a decent one for determining the overall condition.

Nice video. Perfectly explains the process.

Thanks Austin.Its an awesome video.Dont worry about sylishly editing.Content matters the most.

WOw great video man, very simple and incredible valuable info

I just watched something earlier that explains how when under drive there is tangential force on the bevel gears due to how they work which engages them more and locks things up more on the side that is on the surface with more grip. It was very interesting
@kylebanks4003 2 years ago

I think the break free force is great when the drivetrain is pushing because the spider gears a cone shape and they then push on the clutch packs harder

Thanks! Def like seeing the real thing in action next to eachother

What calculation we should consider for Preloaded spring?
