While servicing the differential on a 2004 Silverado pickup truck, I thought I’d take the opportunity to explain how a locking differential works.

My truck is a auto now but geared to be a 3 speed. At 65 mph the RPM’s are
4200. I use a lot of gas. how can I fix this or get it fixed. It has a
shift kit installed also.
are these loud when they lock ?
locked diff is for mainly for drifting ;)
Imagine going really fast and then take a curve with this.
Is this the same on a 03 gm yukon xl?
Awesome information thank you
That’s true, above 20 MPH it can’t lock because the locking dog springs
away just as the locking device springs in the other dog will spring away.
thats really kool thx for that video
wow nice video ; just learned something today 🙂 I knew of posses rears
and limited slip diff’s but did not know of this self locking one… I just
picked up a 2002 Silverado 2500 HD and wounder if I have this rear on my
vehicle..
Great video, horrible design. Had an 09 Avalanche with 70k and the rearend
blew up because the locking differential would not unlock. Common problem.
Great concept, terrible design and execution by GM. Not a Toyota guy, so
don’t turn this into a battle, but their Auto LSD that applies the brake is
a far superior system.
I like my GOV lock very much. You just need to be aware of how it works
and not abuse it!
