If there is not G80 code, it does not likely have a GovLoc in it. It was not standard then and standard today only with very few models. Myself I am not a fan of it for my usage (watch the peanut gallery pipe in). I have been stuck good twice in last 15 years and both times LSD would not have made any difference at all because all four tires where mostly spining anyway Care to explain "all four tires were mostly spinning" I thought you were a fan of open dif's. The reason I am not fond of it is because it makes vehicle more prone to fishtale on ice and I run a few plow trucks and have for many years and directional control is VERY important. Why am I not surprised that you don't use a ls on the rear. I'm trying to think of who else I know that prefer's a open dif on a 4X4 for snow plowing. If you get the snow plow prep, I believe it comes with the ls. Not as a part of the pkg but on the truck. Contray to poular belief, a open diff sends the same amount of torque to both wheels, no more, no less as it can do nothing else. A LSD can send more torque to one axle than the other. ----------------- TheSnoMan.com I guess when I broke my g80 and had to buy two little gears to fix it I |

Not this again, its only an LSD in your head, everyone else knows the difference. Yes it may have a upper limit where it breaks loose to prevent damage but that is not how an LSD works, when the g80 is engaged it is |
to lock, they use mechanical locks that CANNOT slip. The G80 can and
will if enough torque is applied and that is easy to do with oversized
tires. Eaton uses a cam to preload engagement a bit to make it appear
to be a locker but it is not and also it blocks operation above 20 MPH
oe so so above that it is basicallt a open diff with a little bit a
LSD from oil shearing in clutches. Also a classic LSD do basically
work the same as they all have their break limit and some even
increase preload and tighten up even more under torque (like dana
PowerLoc LSD) The G80 is a locker in name only and is going to be
phased out in future and replaced with a more conventional LSD design.

Either way, the opposite side was definitely moving in the opposite direction from the one I was physically rotating. That means open diff, since the drive shaft isn't turning the spider gears are. G80 was the only factory option of a locking differential, they didn't offer an LSD. |
in park or in first if it's a stick, and try again.

transmission. You can't make up your own definition for something just
because you don't agree with it. The G80 does not slip when operating,
therefore it is not a limited slip. Note slip is the operative word,
limited slip does slip some, g80 does not.
