What’s Inside a Helical Limited Slip Differential?

In this video I disassemble a helical, or Torsen, limited slip differential out of a 2000 Acura Integra Type R. During disassembly, I show how this unique limited slip differential works and why it cannot be serviced.

The reason I shot this video in ‘cell phone’ format is because I was originally going to make it a YouTube short. Once I found out they had to be less than a minute I decided to post this as a regular video.

Eric! You're doing it wrong!!! (just thought I'd make it like old times lol. Missed ya dude!!)

[NemoWrenchesevr]

I’m glad your videos are back. During my automotive training watching these instructive videos has made me the automotive tech I am today. Thank you.

A very informative video, thanks. I have a helical LSD in my SSIII Celica and have always wondered how it worked. Seems crazy that it's all based on two flat metal surfaces creating the friction; amazing that they last as long as they do.

Heard of those helical differentials but never seen the inside of one. I've been told that with those that if you get into a free wheeling situation that you need to apply a little braking with the gas to give some resistance in order for the diff to lock up. My '74 C20 has an open diff and I'm undecided whether to replace it with a helical, a standard clutch based, or a manual locking diff. Didn't know that these helicals wear out. Now I'm leaning towards a manual. Thanks, Eric!

1:35 never heard of one of these wearing out. It's gears. It would take a hell of a lot of miles to wear enough material off those gears to where the diff no longer functioned.

The best of the bunch for us DYIers IMHO:
Logging: Nor Cal Timber Faller with Dan Leeper
Automotive: ChrisFix and Eric the Car Guy
Small Engine and power equipment: DonyBoy73 with Donny and help
Furnaces, water heaters, and most every appliance: Jay over at Word of Advice TV
What makes these folks stand out from the rest? their knowledge, their communication skills, and they don't spend a lot of time self-promoting or doing goofy stuff to keep ya' watchin'. They patiently explain everything so nothing is missed. There are lottsa' good folks out there, and these really stand out.

Eric, I just wanted you to know how much you’ve been helping everyone with all of your videos. Whether that be “how to” or just informative videos like this. You’re a great chunk of what makes the community a community. We appreciate it immensely!

It's a pleasure to once again hear your voice and profit from your expertise. Thank You Sir.

Helical LSD is most precise & reliable LSD. it needs to be pre installed in every vehicle! specially the WaveTrac version

[AmiPurple]

Always great to see Eric the car guy on YouTube. Hope your keeping well and awesome

[ezeldo]

Finally, a LS differential video that did NOT confuse me. I've watched other videos about this subject in the past and I was trying to think, but nothing happened. Thanks, ETCG!

I love these "how it works" style videos. 👍

[shadowdog]

That shop is perfect for making videos! Most of your viewers are probably working in a similar space.

The Eaton Trutrac helical gear differential is pretty awesome too. It’s construction is a little different than this but I assume it operates like this Integra Tyle R differential.

[ACB]

Always wanted to know how those work, thanks

The man that taught me everything I know now, miss watching your vids man

[HoldandModify]

How many of us built the rear diff with Legos back in the 80s? :) LOVE THIS RETURN OF ETCG!!

[vijayantgovender]

Thank you Eric I enjoy watching your videos watching from South Africa
